The pressure in the fuel rail is around 35 - 40psi for most cars, if
the pressure drops too far the car can't start until the pressure comes
back up which is why I was asking about the time involved. *IF* one of
the check valves in the pump isn't seating properly the bleedback could
be very slow...

Stick on new wires, you MAY see an inprovement if they're old or at the
very least you'll have a starting date for future changes.

You can test the wiring if you can find a very dark night or very dark
place to park, just start the car, raise the hood and watch around the
plug wires for pretty blue sparkles, if you see any the wires are bad.
