Drop the tank ... use a brass punch to loosen the ring ... to find/replace the pump.

the relay is operated by the computer ...

Check for volts on the outgoing side of the relay ...

check for signal on the input side

check the pressure regulartor ...

If you are still interested ... there is lots more to this. If you are getting weak knees ... remember after you drop the tank and remove the fuel pump ... you are stuck

This can be caused by anything limiting fuel pressure or ignition spark. Tune up items, bad coil/module, bad fuel pump, filter, relay, bad converter, muffler, dirty air filter, vacuum leak, EGR, or others.

Fuel pump will not come on 1996 gmc sonoma 4.3


Well that is the correct action of the pump relay. The computer grounds the pump relay for a couple of seconds to prime the pump then the oil pressure switch provides power once the engine starts.
You should be able to jumper the relay and power the pump as much as you want to test the circuit.

I have a 1996 GMC Sonoma 4.3 V6 that turns over but will not start. Could it be the fuel relay? Where is the relay located?


The pumps themselves are bad about going out on chevorlet trucks. Look at your fuel rail and locate the valve that's on it. It should have a cap on it. It will look like a big valve stem cap. Watch your eyes carefully push down on it and see if fuel sprays out. You can also try a little trick that sometimes works. Have someone turn the truck over while you bang on the fuel tank with a hammer. Sometimes the pump will break loose and start working again. But it will only work temporarily.
