Starts great after days, first couple cranks. I am under the impression that the fuel pump does not prime after the car is hot (maybe I read it earlier in the thread, or another thread). This is the same car this thread was started about years ago. It appears the PO could eliminate the problem by jumping the fuel pump relay. I'm also just want to have all the parts I may need before I pull the system out of the tank. I still need to do my diligence and check fuel pressures at various operating conditions.

That would be the relay.

 

I had a leak in the tank post check valve (essentially no check valve at all) and the car would take a second longer to start. When the pump starts when cranking, it doesnt take long to make pressure as the fuel wont drain from the system with a badcheck valve / leak, only the pressure.

I would measure fuel pressure when you are having the issue and then go from there.
