Yeah I did check them but I'm gonna check them again today... Maybe my eyes are not seeing too good these days... By the way... Does the TSB refer to the 3.4L or the 3.8L??? I have the 3.8L engine...

Thanks guys...

On the 3.8L engine, is the A/C accumulator the round silver cylinder located under the intake air filter box on the drivers side of the engine??

If it is I really have to remove the plastic air filter box to see everything down there around the A/C accumulator...

I dont know about 3.8, but i think you dont have to go to dealer they gonna f$^&%$ you. You can do that your self with electrical tape. Just find damaged wires and tape them.
Keep us posted. Good luck.

I took the air box out and checked the wires in that area... Everything looks perfect... There is one cable that is slightly against the mounting bracket of the accumulator but, like all the other harness cables, it has that heavy plastic wrap around it and there wasn't any chafing... I wrapped it with electrical tape anyway...

This is only thing what i can think of right now. Yuo not gonna use ac now. So look if its gonna happen again. SEnd us your investigation. If this sh#%^&t gonna happen again whithout A/c we gonna find somethig else.
Good luck. Respond if everything is fine.

my '02 Imp has had the hard start problem for several months now, start-stumble and die cold or hot, intermittantly. Today I check the fuel pressure with the key on. It came up to 8psi. I then cycled the key several more times and it finally got up to 44psi. I then checked to see how quickly the pressure dropped off. It fell a little to quickly according to my manual about 25psi drop in and hour or so. Next, I pulled the regulator apart and found the screen dirty and the "O" ring slightly out of place and fuel in the vacuume hose. I proceeded to clean out the regulator and and screen and carefully reassembled it. I again checked to see how quickly the pressure would come up. First toggle of the key took the pressure from 0 to 25 the second toggle of the key took it all the way to 45psi. This was a big improvement from before cleaning to regulator. Next I checked to see how quickly the pressure dropped back off. The pressure receeded even faster then before the cleaning(kinda unnerving). I then started the engine with no problem. Now I relieved all the pressure in the system and again started the engine immediately with no issues. I also cleaned the Idle air control pintle and its well and also cleaned the throttle blades because the buid up of carbon residue on them has been known to cause idle problems. This morning I started the engine with no issues. This afternoon I again started the engine with no issues and let it warm up and then I let it sit for 15-20 minutes and again I stearted the engine with no issues. I have no driven the car yet but if the problems returns when I drive it I will most likely replace the regulator.

well the sketchy starting problem persisted for several more days after everything I did (as outlined previously) so I replaced the fuel pressure regulator last week and the engine has started fine ever since.

One of the first thongs I did was to replace the FPR... That didn't fix the problem for me... Since I have not been running the A/C and I taped off the wires near the accumulator the problem has not occured again... Hmmmmm???

Gems · 12-13-2006, 05:30 PM

Guess what guys, I'm back with this damn problem... After 2-3 months of no re-starting problem, out of the blue it is happening again today... Exact same symptoms as before except we are NOT running the A/C (or defroster)... After running for awhile, then stop for a short time it doesn't want to restart... It fires, stumbles, stalls... Wait about 15 more minutes and it starts up just fine... Right now it's in the driveway and doesn't want to start... So I'm gonna wait 15 minutes and try again... Oh yeah, I have a DTC reader and it shows no codes... Damn!!!!!!!!!!!!!!!!

Gems · 12-13-2006, 05:42 PM

OK I waited the magical 15 minutes and it started right up again... What the hell is this problem???? Flaky fuel pump maybe???

you're gonna need a new ignition lock. It has an anti theft feature that, as with any electro-mechanical part, is susceptible to premature failure.

I thought the ignition lock problem caused the engine to NOT crank when the key was turned... In my case the engine cranks and starts but then stumbles and dies about 1 second later...

Bob, did you ever get that fuel pressure gauge we recommended. Starting to sound like a fuel system problem to me. Fuel pump is the most likely part. I recall you had replaced the fuel pressure regulator.

Yes, I bought a fuel pressure gauge... Last time I checked the pressure readings it was starting normally and I sent the pressure numbers to you... You said the numbers looked good... Yesterday, when it was not starting, I should have hooked the gauge up and took pressure readings... But it was at night and I was pissed off!!... Then 15 minutes later all was good again... And yes again on the FPR... I replaced the FPR about 3 months ago...

It has been so long I couldn't remember. "I should have hooked the gauge up and took pressure readings" <-- Good idea.

Keep the gauge in the trunk. Good luck.
