Ok, I've read many threads on this issue but I'm still at a stand still. 1993 Del sol (automatic). New: main relay, Fuel pump, & ECU. 1 day the car will prime and start without any problems. Next day the issue will come back. Key on : CEL on and stays on. After a few minutes CEL goes off and pump primes and starts. This all started 1 day when the car died and oil had got in the distributor causing the ignition coil to go bad. I replaced the coil, and fixed the oil leak (valve cover gaskets) and have been having the prime issues ever since. Any help would be greatly appreciated

 

since you already remedied the oil leak, it may be the PGMFI relay. If it's the original one, it will need to be replaced. I would grab a few from your local salvage yard (self-service ones).
