a customer has an 84 Fiero brought over on a tow truck.
The fuel pump will only run for about 1 second, even with the oil pressure switch jumped.
but if you cut the power to the pump, and then reapply it, the pump will run again for about 1 second.
I can only speculate that the armature in the pump is getting sideways a little and locking up.
and once the magnetic field is removed, then it centers up again.
so it's got 3/4 of a tank and needs a new fuel pump...

the car gods must have been smiling on me, cause in less than 30 seconds i came up with the idea of wiring in a hazard flasher into the oil pressure pigtail.
The tank was empty in about 20 minutes.
keep this in mind if you run across the same problem.
