Right quick here,
Finished putting new RJC Headgaskets on, all went well. Time to start her back up. Started for a sec and died, over and over the same thing. Fuel pressure gauge showed that pump activated for its 2 seconds and built up pressure. Once I tried to start it no fuel pressure. So I clicked on my fuel pump switch in the engine compartment (How I drain fuel) and she started up and ran fine. Think it's the FP Relay. What do you think?

Sounds probable...if you still have the oil pressure sender on the car, it should turn the pump on after you have cranked the car enuf to build oil pressure over 4 psi as it serves as a back up to the relay.

If you have a hot wire kit, then you will have to figure out which relay is bad. Factory relay, or the hot wire relay
