Hi, all. New to the forum, thanks for any help.

This car runs great for about 20 minutes and then dies. No spark. Let it sit till it gets cold and it will do the same thing. I got into the distributor and checked the coil and ignitor, questionable readings and it leaked oil like crazy, so I put in a remanned distributor. Still the same problem. The 12 volt signal from the ignition switch is always good. All of the dash lights are working when the engine quits. My repair book talks about a main relay and an ECM, but doesn't give a location. Only 215K on this car, I was hoping for a few more miles.

Thanks,

 

It may just be an ignition switch if it runs when in the "start" position. You need to check your ignition circuit out. Another possibility is it may be a relay. So start at the ingnition switch and work your way out of it.

 

It doesn't run with the key in start. It won't start till it's cooled off, then it starts and runs perfect till it gets warm.

Any guesses ??

 

I replaced the main relay, as I read they can have bad solder joints. The engine still quits after warming up. Any ideas ??

Thanks,
