Question From Cara on 2003 Mitsubishi Eclipse Car Wont Start......Help Please

Hi Everyone i was looking for a little help. If anyone can give us any help at all it would be greatly appreciated.

My car details

2003 Mitsubishi Eclipse
2.4 Liter Engine
Automatic Transmission.

We were driving down the highway and the car just lost all power. The rpms went down to 0. There was no warning or noises or anything, it just happened. Prior to this we did not have any problems with the car. The engine turns over and sounds like it wants to start. Its like its not getting gas.

We took the fuel pump out and hooked it up to a battery to see if it was working and it seems to be fine.
We took out the fuel pump replays and tested them as well and they also seem to be working fine.
We checked the fuses and they all see fine as well.

What else could we look at that would cause this?
is there any way to know if the fuel filter is clogged? I hate to buy one for almost $100.00 if that is not the problem

any suggestions are so appreciated.

thanks

Response From Sidom

While on this car even though it isn't the easiest thing to do.....You would really want to take a fuel pressure reading....

Will it run on starting fluid if you spray a couple of shots down the throttle body & then try to start it

Response From Cara

Thank you so much for the reply. It's so appreciated.

We actually have not tried the stated fluid yet. But we are giving it a shot today.

As for the fuel pressure he already took the fuel pump out to check it which released the fuel pressure. And the car will not start, it turns over but won't start.
He would not be able to check the pressure now right?

Response From Hammer Time Top Rated Answer

The fuel pump will activate to build pressure immediately when you attempt to start it if it's working properly.

Response From Cara

Oh ok great . Now we Will attempt to check that , on this car I'm sure it will be a bitch lol.

Thanks so much.

2004 Mitsubishi Lancer no power to fuel pump

Question From Gerty on 2004 Mitsubishi Lancer no power to fuel pump

2004 Mitsubishi Lancer OZ 2.0l 5 speed. 112,000 miles.The car died, no fuel. I have checked the 15 amp fuse under the hood -it's good. The 7.5 amp fuse under the dash is also good. I tested both the #1 and #2 fuel pump relays under dash-they are good. The pump runs fine with 12v applied to it. The issue is this: When testing the relay sockets under the dash for voltage, I have 12v into #1 relay with key on- it completes the circuit and sends 12v to #2 relay. However I can not get the second relay to close as I do not have ground at the other side of the coil on the #2 relay. According to the diagram, ground comes from a transistor (violet wire) in the ECM for the second relay. My question is do I have a bad transistor in the ECM or does some other sensor or system need to send a signal to the ECM to allow the ground to be sent back to the #2 fuel pump relay? What else should I check?
I can email the wiring diagram as so it can be viewed when reading this. Thanks in advance.

Response From Sidom

Wow don't see too many posts like this where someone has basically already done all the work.....

You're gonna give us the diagrams?????????? Man just let me enjoy this moment for a bit.......










You're pretty much already there. You either have a bad relay, open wire or bad PCM.

At the PCM connector C120 pin 8 (pin 20 for an a/t) with the KOEO after 2 seconds you should be seeing battery voltage ( I know you know what open circuit voltage is so I don't have to go into that). If you safely ground that wire and this energizes the fuel pump, barring anything weird you would be looking at a bad PCM. I would still pull codes to be sure but right now can't think of any reason why the PCM wouldn't give you power for 2 seconds (via grounding the relay) with KOEO.
This is would be rare for a Mitsubishi. A common failure would be a bad relay.
You already know the correct pins for the control side, hook it up to your battery and ohm out the load side.

As HT posted, KOEO you will only have power for 2 seconds. Did you test it with a helper? Also tested it while cranking?

Ok I gotta ask......What is your background in auto repair/ electrical?

Response From Gerty

Interesting fact regarding the 2 second power up. I will re-test that relay as well as the socket within the 2 second time frame. I did have my neighbor helping me but I don't think I had the probes in place prior to the 2 seconds. I will test the #8 pin on the PCM and let you know the results.
I am simply a back yard mechanic. I started leaning over the fender when I was about 15 or so, I'm 45 now. I have restored a few cars over the years and always complete all of my own repairs. Many engine rebuilds, all sorts of small and large repairs etc. With an issue like this I try to isolate the component and logically determine how it functions. Then I can begin troubleshooting each aspect of its functionality. Alldata is great as the wiring diagrams are indispensable particularly with this issue. Also, my neighbor is an excellent engineer and together we enjoy troubleshooting this kind of thing- until we are (temporarily) stumped! LOL!

I am not sure how to post the diagram on this forum. Am I missing the feature?

Response From Hammer Time

The way most of us post is to use an image hosting side and link the image here.

Response From Gerty



That should be the wiring diagram. Thanks for that tip!

Ok I did skin the violet wire a bit a few inches before the ECM connector under the dash and grounded it. With the key on I have power and the fuel pump running. I assume this is suggesting a bad ECM. The issue is compounded as even with the pump running, albeit with this temporary ground, the car will not start. I am not sure if it is the ECM or as I stated earlier perhaps another sensor that has failed and not allowing the ECM to send that ground. I agree I need to pull codes. I will see if I can get a hold of a scan tool. In the mean time I will study some of the other diagrams for any clues.
Thanks

Response From Sidom

On this one I would probably backup a bit and check all the basics. With everything hooked up the way it should, check for spark, fuel (you already know about that) and injector pulse. See what all is missing. You really want to pull the codes as well.

I would make sure you are working with a battery that has been load tested as good. Get a test light and check all the fuses in all the fuse boxes.
When testing circuits the best way is to backprobe the connector with a pin, paperclip what ever you have handy. If the wife has one of those T pins, those work real well. Most connectors have rubber weatherpacking to protect the clips, a little electrical cleaner or throttle body spray on them and the pin slides in real easy. If it can't be backprobed the next best thing would be a wire piercer but those do leave a hole. What ever is done to the wire needs to be sealed real tight or there will be problems down the road. Ideally you want to leave no mark but if you have to, then leave as small of mark as possible.

Maybe a little history on the no start would be helpful.

It's just nice to get a post with a specific question rather than "My car doesn't start..............why?"...........lol and then for the OP to offer diagrams......lmao...... Usually it's the other way around....like 99% of the time.....

It's possible to have a bad PCM, you just don't see it that much on Mits, now if this was a Chrysler..........

The other stuff really needs to be checked 1st and if it started looking like a PCM then all the PCM powers and ground would obviously need to be load checked at the PCM connectors....

Response From Gerty

I was thinking the same thing about starting from the top. I intend on going over all the basics just to be sure it is not something obvious. I will check the battery however that is only a few months old.
The starting failure was as follows:
I had filled the tank with fuel and drove about 5 miles to enjoy a libation with a friend at a restaurant. I was inside for 20 mins at best. When I started the car it fired only to stall immediately. That was all she wrote. It was an easy diagnoses at the restaurant as I knew I could not hear the fuel pump. I assumed fuse or relay. I checked them and even swapped the relays -I used the A/C clutch relay for this with obviously the same results. I towed it home and began the aforementioned process.

Response From Gerty

Well I did pull the codes this morning. I have two: P0335-Crankshaft sensor circuit malfunction and P0122- Throttle Position sensor circuit low input. This helps. I am thinking the crank sensor is telling the ECM no go with fuel delivery. I will know more when I test each sensor. I just don't have time right now as I have to travel today for the holiday. I may have caused the throttle sensor code as I was checking the connector the other day. I was hearing some noise coming from it when I was checking the MIL relay under the hood.

Response From Sidom

I hear ya on the holidays. I'm in & out as well, just getting ready to start my Xmas shopping.....wow getting it done early this year....

One thing I'll toss out real quick, before you get too deep into testing the sensors, verify your ref voltage. If something is pulling down the ref V or it's plain gone, the PCM will toss a couple different codes for different areas........

Response From Gerty

Well I began the next stage of troubleshooting with the two codes I pulled. As I stated in my prior post I felt I may have caused the TPS code. I conducted all of the steps in troubleshooting the crank sensor. Voltage at various locations including the ECM, continuity etc. All Data has a great flow chart for this type of thing. I was not finding any real issue. I was at the point of simply inspecting various connectors, wiring harness etc. related to the crankshaft circuit. It brought me back to the MIL relay harness connector. I checked all of those areas with no obvious failures. The next steps are to get under the car and pull the lower timing belt cover and get a closer visual on the sensing blade et al. For laughs I tried to start the car as I was done for the day because I was going to get under the car later. Well to my utter surprise it started up immediately! I am unsure of what the issue actually was. If I had to guess I would lean to a connection issue at either the crank sensor or the harness connector at the MIL relay. I will perform a test today with the scan tool while the car is running to see where I am at with some systems.
I am sure a faulty crankshaft sensor signal would have caused the no start condition. I would like to pin point the actual issue if I can. I intend on trying to replicate the failure by closely working on the harness connector at the MIL relay as well as the crankshaft sensor connector. I am pleased the car is running but I never like the mystery fix!
Thanks for all the help.

Response From Tom Greenleaf Top Rated Answer

Just a note on the comment "Mystery Fix."

When chasing stuff down do ONE thing at a time and test. Then move on to next be it a connection or item if you do more than one at once you''ll likely not know which was the trouble and may still be lurking. It's better to know the problem area or circuit than not if it re- occurs. Dang intermittent stuff causes hair loss

Re: Images? Always gives me a hard time but many things you can see you can just .... drag (turns blue, arrow over blue, right click on that anywhere then in your post and get the blinking bar where where you want the image, diagram or whatever and right click and the 'paste' option should show. If not it's got an attitude - you may see it and when posted you get the famous red X. If I see it as a link I can usually get your post to show directly via editing your post.

Speak for myself but if I do that I near always don't touch any script and say I messed with it to make it show instantly. Wadda I know about these damn machines? If it works - do it

Response From Hammer Time

That's how the PCM controls the relay. It's not turning it on for one reason or another and that's what you have to determine. You have to under stand how this works too. Most of then only power a 2 second prime and then shut off until the PCM sees a tach signal.

Question From x8jason8x on Re: 2004 Mitsubishi Lancer no power to fuel pump

Sorry for the necrobump, but I'm having a similar issue.

What happened is while driving, I stopped to check my mail, and turned the hazard lights on. The car died when I pushed the switch, and would not start again. It threw p0340 crankshaft sensor circuit error. I replaced the sensor and checked all the harnesses and contacts, no obvious problem, changed a faulty ignition lock cylinder and starter, and now, there is no power to the fuel pump. The circuit powers while cranking, and the pump works with 12v applied. Both relays are getting power, and all fuses are good. I am at my wit's end, and I am simply stumped as to what I should do now. The engine cranks, and as I said the circuit gets power when it's cranking, so I am simply lost. If anyone can help, it would be greatly appreciated.

Response From x8jason8x

Sorry, car is also 2004 Lancer, ES model 2.0 5 speed.

Response From Discretesignals

Is the P0340 code still showing up?

Response From x8jason8x

Yes it is still showing up. Accompanying text is as follows:

P0340

Camshaft Position Sensor A Circuit (Bank 1 or Single Sensor)

Fuel System 1
Open - Loop Drive

Sorry for the delay, a bit hectic around here.

Response From Discretesignals

I don't know if you can do this, but remove the oil cap and look at the camshaft. See if it spins when someone cranks the engine.


There is also TSB on the P0340. It may apply:

No.: TSB-07-11-001

DATE: January, 2007

MODEL: 2002-07 Lancer 2.0L

SUBJECT:
HARD TO START ENGINE DTC P0340 (and P0335)

PURPOSE

The engine may be hard or impossible to start and MFI DTC P0335 and possibly P0340 may be stored due to abnormal wear to the camshaft position sensor support. Oil grooves have been added to the camshaft position sensor support to improve lubrication.
f a customer has a vehicle with the above condition, replace the camshaft position sensor support with the new part listed in the PARTS INFORMATION section of this bulletin.

AFFECTED VEHICLES
2002-07 Lancer 2.0L

PROCEDURE

Replace the camshaft position sensor support as described in Group 11B, GENERATOR AND IGNITION SYSTEM REMOVAL AND INSTALLATION, of the appropriate service manual.

IMPORTANT!
Carefully remove all debris from the end of the camshaft position sensor before reinstalling it.

Response From x8jason8x

Camshaft isn't spinning. Can't say if the TSB applies but at this point the best I can do is clean out the support and re-lube the sensor.

Response From Discretesignals

If the camshaft isn't spinning while your cranking the engine, you have a problem with the timing belt.

Response From x8jason8x

Ok, timing belt had stripped teeth. I wasn't aware of the number of sensors in this thing haha. Anyway, I replaced the belt, lined up the timing marks, but I'm still not getting power to the fuel pump. It's cranking, but won't start. Throwing 2 of each OBD p0335 and p0340. Is it possible I have the cam out 180 degrees? Ugh haha this is driving me nuts.

Response From x8jason8x

Disregard last post, I had put the wrong sensor in the camshaft sensor slot. Thanks for your help!

SOLVED.

Response From Discretesignals

Were you able to get the engine started?

Response From x8jason8x

Yes. The wrong sensor came from a guy that ordered it for me, and insisted on putting it in. Turns out he'd ordered a crankshaft sensor. Thankfully, I didn't let him toss the old one, and when I put it in, it fired right up, and is only throwing the cat sensor code now, which I'll replace myself. Thanks for your help!

Response From Discretesignals

Good to read you got your vehicle running again. Your pretty lucky because that engine is labeled as an interference engine. The cam most have stopped spinning in just the right place. Thanks for the follow up. Closed as solved.

Response From x8jason8x Top Rated Answer

Ah. Will get on that, and update what I find.

Response From x8jason8x

I haven't had the chance to get a code reader again yet, but I can tell you that it wasn't cranking before, it was just spinning and not engaging. I will get a code reader asap.
