Fuel Pump Pressure ?
1993 GMC Truck C1500 1/2ton P/U 2WD 5.7L TBI 8cyl........ . I know it should be 9-13, it test at 13 but drops to 0 when pump sound stops,I start engine and it 's back up. No sign of leaks. Engine cut out on me and it seemed like a fuel problem. It did not want to restart till it cooled down.

Re: Fuel Pump Pressure ?
1st thing to do when this happens is check for spark if ok see if the injectors are spraying.

Re: Fuel Pump Pressure ?
The small positive wire from battery has melted to exhaust manifold. I thinking this maybe the problem.
