What's Your Best Guess

ECM/or chip - Ing. Coil - Pick Up Coil in the Dist.

If you had to make a guess a on one of these over the others going dead after getting to normal running temp. and restarting cold no problem which would it be.

I'm also going to guess at what you're trying to ask.......I would say pick-up coil in the distributor.

Re: What's Your Best Guess

Test it hot and cold . When mine died it ran perfectly for 10 minutes then you had to wait for it to cool down . I changed the module first because it was rolling the dice ,module or pickup coil . Then when it still did it I tested the pickup coil - good cold ,bad hot . So now I've got a spare module .

Re: What's Your Best Guess

Years ago I had a problem very similar on my car. It would start cold, run fine until about 15 mins later and stop. Once cool again it would start...

Ended up it was a bad chip...

Re: What's Your Best Guess

Ok now your the one that has my attention for sure I got this car with a start up run ok but untill acc. it would bog out it event. got worse to a no start then I changed out the ECM and would start right up now only dies off after hot and Im wondering if I do have the chip prob. no codes etc. tried new coil a while back not the answer and module good and fuel psi fine thanks for the answer I was realy looking to see if that was a common or not even prob. but now you cant find a new stock chip and I want to drop one in if I do it not mess around with programing thanks again, George.

Re: What's Your Best Guess

I did the same thing. I changed my coil w/ no result, then my ECM w/ no result... Then I put another chip in and it was fine.

What setup is your car? 305/350? TPI? MAF car? AT? You can probably find someone w/ a chip for you to try...
