Fuel pump relay overheating..tried new fuel pump, relay,repair engine ground..believe it is a loose ground from relay to somewhere, can't find location of ground

The relay grounds are the fuel pump and the ECM. If it over heats, it's because the pump is pulling to many amps. Replace the hot wire to the pump and the ground wire from the pump. One or both will solve your problem.

Where is fuel pump relay switch located on a 94 gmc Sonoma. Cannot locate to test. Truck starts but as driving the is a click noise and shuts off. It restarts after a minute. Please help

Check in main fuse block with other relays. Should be labeled. Relay kicking out may be caused by overheating = bad fuel pump or dirty filter. Test fuel pressure too.

No power to fuel pump or gage replac relay still no power

If the engine cranks and tries to run but dies when the key is released then the oil pressure/fuel pump cutout switch or wiring is defective. My 96 and 97 GM trucks had problems with the relay connections getting overheated and the terminal in the fuse/relay box didn't make good connection even with a new relay. If the fuel pump is in the tank then either the connector on the top of the tank for the fuel pump module is loose/defective or the fuel module ground connection at the engine is loose/disconnected.

1999 tahoe, was running rough, I changed the plugs,that didn't help. Then for no reason it ran like new, then is was stalling and wouldn't rev up, Then it wouldn't start at all. I noticed no...

now that leg won't lite up and the fuel pump won't work ????? The PCM - engine computer supply's B+ voltage to control the fuel pump by energizing the relay .

If it is cranking with out turning over I would check the fuel pump and ignition relay, crank and cam sensors.
Basically you need to figure out if you have a spark issue or a fuel issue. (as long as you didn't have a serious overheating problem). One way to help you figure this out is by spraying in some starting fluid while cranking the engine. If it starts you have a fuel problem, if nothing then you have a spark problem (assuming you didn't blow the head gasket from overheating and was running normally before this happened).
Based on what you've already done here are my recommendations:
No spark: check ignition relay
No fuel: check fuel pump relay (aka shutoff relay, aka fuel pump shutoff relay), crank and cam position sensors, fuel filter.
There is also one other possibility, that the timing belt snapped. You would need to remove the timing cover to check this.

Both fuel pump relays run hot. I have replaced both of them. The truck started and ran for about 30 minutes then quit. I replaced the relays and it ran for a few minutes and quit again.

You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!
