Jeep Mystery Starting Problem

Showing 2 out of 9 Posts | Show 7 Hidden Posts
Question From mdelay on Jeep Mystery Starting Problem

1993 Jeep Grand Cherokee 4.0L Unsure on mileage.

Jeep is at the mechanic shop because it would not start. It had a split wire in the wiring harness. It has a new header, ignition coil, cps, distributor, fuel injectors, computer, and many other parts. Timing was off, but is now set. The mechanic is able to get it started only with the #1 spark plug out. Any ideas?

Response From nickwarner

Doesn't make much sense. Has he done a compression test yet?

Response From Hammer Time

I'd also look for something that may be causing crossfires like the firing order or cracked distributor cap.

Response From Discretesignals Top Rated Answer

Check for plugged exhaust system or cat? Maybe taking the plug out allows the exhaust gasses to pass through #1 exhaust valve. (WAG)

Response From mdelay

We bought it not running, the previous owner said he thought that it was a fuel problem. After having someone take a look at it, they discovered the ECU was not communicating to the car. Took it to the dealership to have it "flashed", since previous owner said he replaced it. They said it was not able to be flashed because it was bad. They replaced the Crank Sensor, and Distributor, and new ECU. It was running, but had a terrible exhaust leak. Didn't drive it because the leak was horrible. Got the header replaced, now it won't start again. Found wiring harness to have some wires melted together. Replaced wiring harness. Replaced the fuel injectors, new plugs, wires, ignition coil, new battery, and another Crank Sensor. Still nothing. Someone suggested the timing may have been thrown off. Had a new timing chain/belt put on it. Still nothing. Took it into the mechanic shop and found a wire in the wiring harness was not connected, but still nothing, ran a new ground (which he said helped).

Response From Hammer Time

Most likely that melted wiring is what ruined the first computer and may have done it again. Computers don't just die of old age, they are killed by something.

Response From mdelay

Final report is a clogged catalytic converter. Unplugged o2 sensor and it starts with # 1 plug in.

Response From Hammer Time

0/2 sensor Unplugged or removed?

Response From mdelay

Removed

2005 Jeep Liberty Exhaust

Showing 5 out of 6 Posts | Show 1 Hidden Posts
Question From 1998_Sebring on 2005 Jeep Liberty Exhaust

I am looking to purchase a 2005 Jeep Liberty, and the particular one I like has a black buildup or burnt oil or something like that all inside the tailpipe. Is this normal?

Thanks!!

Response From Tom Greenleaf

That's a neat reminder of some older ways to tell about an engine!

Yes and No??

It's not really expected to be sparkling clean but I wouldn't think or say sooty is right. Kinda would need to see that in person and would still wonder some.

Perhaps make your deal contingent upon an exhaust gas analysis but before that if all else seems fine make an arrangement to check the vehicle again when stone cold like an overnite. Check underhood for evidence of it having been run before you start it first for the day and you'll know how well it really starts and runs cold AND have a chance to see if there's visable black or blue smoke out tailpipe at start up. In cold weather there is some steam which is normal in certain conditions as you should have seen before - I'm talking BLACK (too much fuel) or BLUE (oil does that) smoke puffs or any rough running. Hate to start off with any problems - enough happens anyway.

If dealer or private sale then insist on an independant check at a place of your choice. That's a good idea anyway for used car buying,

gotta stay on your toes tom!

Response From dmac0923 Top Rated Answer

yes black residue in the tailpipe is normal. how many miles does it have? how did the oil look on the dip stick?

does it smoke?

Response From 1998_Sebring

There is no smoke, and the oil looks normal. It has about 40,000 miles.

Question From Guest on code for jeep liberty

2006 jeep liberty, 3.7engine, 87,000miles

check engine light went but now is off.

just pulled code p2098 can anyone tell me what this is.



thanks john

Response From Hammer Time Top Rated Answer

I had a Chrysler vehicle not long ago with that code that drove me crazy. The first think to look at is the downstream O/2 sensor itself. If the sensor is not the problem, then the exhaust system has to be examined very closely. Chrysler has an internal memo about cracks in the catalytic converter that causes this code. They tend to split right along the seam weld but you have to look very closely and possible pressurize the exhaust system to find it.

Response From Guest

thanks for the replies, where would the downstream o2 sensor be located. also now that the check engine light went off could this have been just a hiccup, or is there a problem.

thanks again guys

Response From Hammer Time

There are no such things as hiccups in computer systems. The problem occurred at one time and will likely occur again.

The sensor in question here is marked #4 in the pic.

Response From Guest

thanks for the very detailed responses
greatly appreciated.....john

Response From Sidom

In a nutshell that is a rear fuel trim lean code.......

That is a 2 trip fault code (meaning the vehicle has to be driven twice under the corrrect conditions to set)

Three passing trips will turn the light off by itself but code will be stored........

Question From joebaker on 96 jeep cherokee wont start! HELP~

1996 jeep cherokee
4.0 straight 6

changed the coil, changed the distributor pickup plate.
checked fuses, no spark.
battery is good shape, all grounded.
timing is good


is there a relay or something that i am missing that is for the timing? any ideas?


i turn the key and it cranks but no spark...

HELP!!!!!!!!!!!!

Response From Indytech Top Rated Answer

Do you have spark and fuel ?
What is very common on these cars is the crank sensor which is on the top front left side of the tranny bell-housing
near the engine /tranny attaching bolts.the wires from the sensor go up to the inlet manifold passing the exhaust pipe here they tend to burn from the heat from the exhaust pipe Just a thought

Question From completelyhis on o2 sensor on '95 jeep

My o2 sensor on my '95 jeep keeps faulting. when i hook up the code reader it says something about high voltage something or other (sorry, don't have the code reader with me, and my memory is worthless).

i replaced the sensor, but it keeps happening. any suggestions as to what to look for?

See if you can get the exact code numbers and post back. There are too many variables on the O2 sensors. Vacuum leaks, too much fuel, not enough fuel, exhaust leak, exhaust restrictions, MAF or MAP reading wrong, bad wiring, bad connections. These are just a few of the things that can cause an O2 code.

The exact code is

21
Oxygen sensor bank 1 position 1 shorted to high voltage


I just replaced this sensor about 2 weeks prior to the code showing up. I notice a foul smell in the exhaust, plus it seems to be putting out a nasty blackness (dang, new muffler and cat. conv too!!)

The check engine light comes on/off intermittantly, the engine runs much worse when the check engine light is on, so I do think it is a "real" problem.
