It's worth checking to see if this the standard EFI Main Relay problem.
The sequence you want to see:
1) Turn ignition to ON. MIL illuminates (a click is heard)
2) 2 seconds pass, MIL goes off (a second click is heard)
3) Turn key to START. Engine cranks and fires (third click is heard)
If third click is NOT heard, main relay is not holding fuel pump relay
closed and pump won't run. Car will fire then stall. If fuel pump relay
won't hold shut at all, car won't start.
The relay is behind the dash, just below and to the left of the steering
column. My ears are bad, so I have to put my hand under the dash, touch the
relay, and feel the clicks rather than hear them.
If you've got a fuel pressure check valve problem, fuel pressure may bleed
off after you shut the engine off. To check, turn the key to ON, wait for
the MIL to go off, repeat several times in succession, then immediately try
to start the car. If the car now starts reliably, the check valve is bad.
If you hear three clicks and the check valve thing doesn't help, then check
out the distributor cap issue outlined by Graham.
