I have a 1991 Honda Accord DX with 160K miles. When the car is hot, the car intermittantly starts, it will turn and shut right off. If you let it sit for about 5 minutes, it will start. It sounds like it's getting some fuel, because it starts and shuts right off. Fuel injection is good, had that cleaned out already, distributer cap was changed already, on a scheduled tunup. Has anyone have this problem before? Could it be the injector relay? Any input will be greatly appreciated.

Thank you in advance!

Here is a post from accordracing.com, he seems to of had the same exact problem I had. But it never showed what the real problem was: http://www.importstreetscenes.com/te...ght=main+relay

Im having problems starting my car every now and then. Its only happened 3 times in the past month and a half. After running the car, if you let it sit for about 30 minutes (just long enough to be in a store) and when you go to crank the engine, it'll turn over and act like its just about to start, but it wont fire. Let it sit for about 10 minutes and vroom, off you go. The first time it happened it was raining so I figured maybe some water leaked into my distributor cap and was causing it to not start. The second and third time it happened it was completely dry out!!! I am confused, I referenced to my haynes manual and it provided absolutely no help. Once the car is running it is absolutely fine, runs without a hitch. This only happens when starting it. Any suggestions/comments/help.

 

My sister had the same problem with her 90 Integra. I'm still not sure what the cause is or was. It doesn't seem to be doing it anymore, it's kinda on and off sometimes.

 

PGM-FI Main Relay. The relay goes off of cabin temperature where not engine temp. Replace it and you should be all good.

Heres a link of earlier post.
