1994 Pontiac Grand Prix

Showing 5 out of 5 Posts
Question From tacmale on 1994 Pontiac Grand Prix

I have a 1994 Pontiac Grand Prix that used to stall after driving for a while or if left idling. Replaced the fuel filter, fuel pump, fuel pressure regulator, Ignition Control Module, plugs, wires, and fuel pump relay. Now it will start for about 3 seconds then just dies. Was wondering if it could be either the crankshaft or the camshaft position sensors. Any help would be greatly appreciated.

Need to add when i run an obd check no codes show up.

I realized i did not give very good info, here is a list of things i have replaced or tested on the motor. It is a 3100 SFI I have to work in the open and live in Washington and have to do this between rain stroms.
Fuel pressure-good
Fuel pump relay-replaced
fuel pump-replaced
fuel pressure regulator-replaced
ICM-replaced
Plugs and wires-replaced
engine has spark and fuel or so it appears it wants to start afetr disconnecting the battery and leaving it sit to clear the memeory. Starts for just a few seconds then acts like the timing is off tries to start but backfires once in a while. But just cranks over, battery has full charge.

Response From steve01832 Top Rated Answer

You should start with checking the fuel pressure with a guage. It is possible that the fuel pump relay is pulling in during key on engine off but may not be getting a signal after the engine fires causing it to die. Key on engine off fuel reading should be around 35 psi. If this is ok then start the engine and let it stall. Check the guage. If it is holding at 35 psi the fuel delivery is ok. If the guage is way down, check for spark at the plugs and check for injector pulse by installing a noid light into one of the injector connectors. If there is no spark and no injector pulse, replace crank sensor. If there are different symptoms, post back with the results and we can go further.

Steve

Response From tacmale

finally got some dry weather to work in i got no fuel pressure when it placed my gague on it. I have replaced the fuel pump relay and the fuel pressure regulator and a new fuel pump. Still no pressure reading. I tried squirting gas in thru the throttle body but even that didnt start it.

Response From tacmale

Went to check the crankshaft position sensor which on the 3100 sfi v-6 is located on the firewall side of the engine. I noticed the wire way down looked burned. Got a light and sure enough the clip holding it had come loose and the wire had fallen on the exhaust and burned thru. Simple fix, just had to rotate the motor and get at the sensor from the front of the engine. Thanks for all the help guys got me going in the right direction.

Response From whitey79

i assume its a quad 4? my lil sister had one and i had to replace the cps, and the plug wire assembly(sorry i forgot what the deal is called the holds the plug boots. i cleaned it also). the camshaft position sensor was a real pain in the rear to replace. i would reccomend doing it in a garage. if you have to.

1992 Pontiac shuts down when driving

Question From slortiz on 1992 Pontiac shuts down when driving

I have a 1992 Pontiac Bonneville, V6, 122,000 miles.
when driving during normal conditions, service light will come on and then car will shut down completely.
When this happens, I will coast safetly to the shoulder of the road, wait a few seconds and then start it with no problems. The service light will no be on. I have taken this to a few places for repairs, but no luck as they say, they are not able to diagnose the problem, if the service light does not come on or stalls when they drive it.
I would like to know if this has happen to anyone before?

Response From Hammer Time

If you are getting a check engine light, then there will be a stored code that can be retreived. if you live near an AutoZone or Advanced Auto, they will scan it for free.

Response From slortiz

Like i mentioned before, when the light goes on, the car shuts down. all power. When I re-start the car, light stays off. I don't know what is causing this shut down. I have taken this car to Pep Boys and Firestone with no luck. They tell me the same thing, if this doesn't happen to them, how are we going to diagnose the problem!
Thanks for the thought, but as you can see no light, no problem.....

Response From slortiz

I have had the alternator checked, fuel pump pressure. all good. I replaced the fuel filter, starter (as it was dragging ). We replaced the cam shaft sensor and someone said it might be the oxygen sensor??

Response From Loren Champlain Sr

Slortiz; These are classic symptoms of either ignition control module or crankshaft sensor. Neither will always set a DTC. A bit more diagnosing will be needed. When it does die, do you have spark and/or fuel?

Response From slortiz

When this shuts down, it will start immediately, but sometimes idle rough. I will then turn it off and re-start, then it will idle smooth. Spark isn't an issue, becuase I don't have a problem starting once stalled.
I have this car at another mechanic and he thinks the gas might be contaminated, but he is still looking into it further.
This is actually my daughters car and today I drove it again, sure enough, stalled at the light, like someone turned off the key. I put it in park and it started immediately. When I drove further and stopped at lights, I noticed the idling got rougher, sometimes it would stall. The stopping and going was when I noticed it got rougher.
When I drove down the highway, car ran smooth, no stalling, no issues.

Response From Loren Champlain Sr

slortiz; I should have read your symptoms a bit more closely. Sorry. If it starts right back up, I'd probably disregard both the module and crank sensor. A fuel sample would be a very good idea. Sorry if I steered you in the wrong direction.

Response From Hammer Time

I wouldn't disregard either of those simply because it starts back up in fact I would probably suspect the crank sensor the most under those circumstances although it could be almost anything.

Response From slortiz

ok, this is what we have done so far, replaced the crankshaft sensor, control module, new plugs, plug wires, tried checking the wire harness for any pinch/cuts. Checked the fuel pump pressure when it would die on us, all is good. We thought maybe contaminated gas, but it would do this all the time (rough idling). We are getting spark. After all this, same issue.
When you stop and go, this is when it acts up more versus driving down a highway/freeway.
I have been told that it might be the ECU?? any more thoughts out there.

Response From Hammer Time

Have you been able to monitor spark, injector pulse and fuel pressure during the failure to determine which one of those is dropping out?

Response From slortiz

Spark was good, Fuel pump pressure was just above 40. I haven't tried the injector pulse.

Response From Lanf3ar

We just solved this problem on my friends bonneville.. Its your mass airflow sensor yank it out and spray it with brake cleaner fixed our problem quick . The mass airflow sensor was not always shooting out the code either. If you clean it and it still doesnt work you might need a new one easy to find at a yard and simple to pull out. Oh is this the supercharged ssei? And it would still be a good idea to go get the codes read. These cars along with the grand prix have alot of problems with them. My friend is on his 3rd one in his GP

Response From slortiz

all the sensors have been replaced on the throttle body, still nothing.
This is not a supercharged ssei.
Checked with teh mechanic and he said, no codes come out on the computer.
He was waiting on the ECU if it needs flashing or not..

Response From Lanf3ar

Your 100% sure the Mass airflow was changed? Still be a good idea to clean it.

Response From slortiz

It was replaced and then we rechecked the wiring to make sure the connection was good.

Response From Lanf3ar

Take your car around the block a few times nice and slow and run through your gears (1,2,3) see if it still happens

Response From slortiz

we were messing around with the mass air flow sensor and the rpm's were going crazy, so we are taking this off and taking it back to the autoparts. This is the one sensors we first bought.
more to come later.......
thanks for the tip

Response From slortiz

So.. we took the mass air flow sensor back to the auto parts for exchange, put the new one and success!!!!
Goes to show, never trust new parts??
Thank you all for all the tips, i really appreciate it.

Thats good.Got to love after-market parts.Happens to me alot.

Response From autojoe

The code should still be in the computers memory whether or not the check engine light is on or not.I understand that in order to test the circuit/component you have to have the problem show up while you have diagnostic equipment hooked up to the circuit/component.I don't know how many times I have driven vehicle with a scan tool and a labscope hooked up driving down the road looking at several sensors at one time trying to get something to act up.The code in memory will give you a starting point to look or start a diagnostic starting point.1992 is an obd1 system and does not usually give you to much to go on and most of the time will not even trigger light when there is a problem.Like mentioned above you need to have ecm scanned for history code or codes stored in the ecms memory.Take to autozone and then report back here with code.If there is no code stored in the ecm then there may be a problem with the ecm.There are lots of things that can cause total shut-down including things that would not be sensed by the computer like the ignition switch.The fuel pressure would have to be monitored while driving and when stalled look and see if fuel pressure stayed up during the stall.I use a remote digital fuel pressure gauge.When you say all power is lost........are all the dash warning lights off/radio ect.?All the dash warning lights should be on during stall.

Response From autojoe

I wanted to add you stated that the service light came on when car stalled....it should.all the warning lights will come on just like when you turn key to on position before you start car.does car stall during acceleration load or during de-cel with foot off gas pedal or during turns?

Response From autojoe Top Rated Answer

I wanted to add.....start car and lightly tap on the side of the ecm and see if you notice change to rpm.If so replace ecm.I have seen some bad ecms around that year.Also try wiggling the camshaft position sensor electrical connector and listen for any change.Just some thoughts.

Question From jnowak on 2001 Pontiac montana hard start hot

2001 Pontiac Montana 140,000 miles (Minnesota)

Starts excellent cold in any weather, Starts excellent within a couple (1-3) minutes from shutting down. Also, starts excellent after about 1 hour of sitting. Always runs and drives excellent. By starts excellent I mean within about 3-4 revolutions of engine. about 2 seconds.
Turns over, never needs jumping however battery is 6-7yrs old but, doesn't seem weak.

The problem is when it sits for more than 3-5 minutes hot. It will start as usual then immediately and I mean immediately idle down and die. If I time a pump of gas just right during start up it will just stumble from 300rpm to 700rpm or so for about 3 or 4 seconds and then run just fine. The more fuel I give it the faster it corrects itself. There are no codes showing, I replaced plugs and plug wires, (old plugs just all evenly worn no other signs, or colored etc. ) new fuel filter, air filter, drivebelt, tried fuel system cleaners. I have noticed no difference. I checked for fuel in vacuum line of fuel pressure regulator and noticed no fuel (vacuum seems good) I think fpr is good. Could a faulty or intermitant camshaft position sensor be the cause. Seems like some sort of heat soaking issue.

Over the course of 30,000 miles (1 yr) this problem started minor with slight hesitation and rough idle at startup to now needing fuel to keep running. Always occurs about the same in any weather. One odd thing is that the remote start will not start it at all it only turns the engine over for what seems to be one-two revolutions max and it it doesn't start it will try again about 30 sec later. Would very much appreciate help...........

Response From Hammer Time

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.



Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

I allready read this Copy and Paste response on other questions. Though I appreciate the effort. Has anyone else actually encountered this same problem and solved it? Let me know. Not looking for Itemized lists of things to check I allready found that on every other site and I do not have all the tools. Again looking for some one who has experienced this and solved it.

Response From Hammer Time

You may have seen that that test sequence in hundreds of places because I have helped hundreds of people diagnose their problems using it. I wrote every word of it. That is the information needed to conclude anything and if you are too lazy to do the testing or are expecting a magic answer, go get yourself a crystal ball.

Response From jnowak

Would love to play games with you internet mechanics but, Like I said looking for someone who had this issue. So, since this is my post I would ask you not to respond unless Like I said earlier you have experienced this problem.

Response From Hammer Time

You can try to control who responds to this post all you want but unfortunately, you do not run this site. Now it you want help, then you go perform the tests, otherwise stop wasting our time.

We don't guess at things. You supply us data and we will analyze it for you, if you want the crystal ball method, then go for it.

And that's why there are mechanics, like hammer said only way to know for sure it to follow his steps we don't like to guess and have people throwing parts at vehicle trying to fix it. there are a lot of problems that can cause the same symptom so even if someone did have the same issue it may not be the same problem.
