Had this prblem since Day one. Drive it around and let it sit for any amount of time and go to start it and it wil throw a cel while cranking and not start. Turn the key off and on til the light goes away and it will start right up. I've changed the main relay a few time and still hasent done anything. Thinking maybe the pgmfi relay. anyone exprience this similar problem?

 

Ignition Coil or the module in the distributor? What cel is it throwing?

 

Not sure, I guess I could check it. This has happened with 3 different motors and swaps.

 

And that's why i think it's something to do with the some chassis relay
