Lately (and somewhat intermittently) my 95 will have a hard time starting. The engine will crank and not start but if I turn the key off and then try to start it again right away it will fire up immediately. Car seems to run totally fine once it's started. Yesterday I hooked up my fuel pressure gauge and with the key on and engine off the gauge was not showing any pressure. With the engine running I was seeing 30-31 psi. With the vacuum line removed from the fuel pressure regulator I was seeing closer to 40 psi (also no signs of fuel leaking from FPR). When I shut the engine off the pressure would drop back down to 0 immediately. I'm curious if anyone has had a similar issue and what the cause was. From doing some research it sounds like it may be the check valve in the fuel pump? Is there anything else that could cause symptoms like this? Leaky injector? For what it's worth, the car has a new Motorcraft fuel filter, plugs, plug wires, cap, and rotor.
