You can mount a fuel pressure guage to the engine fuel rail at its bicycle valve bleeder, with tof see if it has pressure when you first turn on the key to start. You may be able to hear the fuel pump running by listening at the fuel tank fill cap that you would remove for that moment. By turning on ignition to start, not run, you are energizing the fuel pump to bring up pressure that should happen in several seconds. So, check if it gets to normal fuel starting pressure, maybe 45 to 60 psi. Then turn key all the way to run, to get car engine running and watch the fuel pressure to see if it stays pretty constant at that 45 to 60 psi. Turn engine off, and watch how long it takes for fuel pressure to drop, and it should not happen fast but instead over 15 minutes or more. That might indicate your fuel regulator valve isn;t working right. Is it possible your starting system is the culprit, say some battery cable loose that may make starting hard or eventually quit until you tighten these cable ends at battery and starter.
