Where is feul pump fuse - 1992 Oldsmobile Bravada

the feul filter get a book and look were its located but it wouldnt be the ignition fuse it would be feul pump fuse when u turn the key in on position not starting the car youll hear the feul pump at the back of car kick on if u dont hear it replace the feul pump if it dose then its ur coils

Sounds like vapor lock. Leave the cap from the gas lid undone for a little while.

Yes, it can be the relay. What I do is unplug the relay and swap it gor yhe horn relay. If this doesn't work, I use a volt/ohmmeter to probe the relay socket. Doing this, I can usually find the problem. With the key on , there should be two terminals in the socket that have battery voltage and one that is grounded. The last terminal goes to the pump and should show low ohms to ground. In your truck, the relay coil is connected to ground and turned on by the ecm with a positive signal. It also seems to depend on the oil pressure switch, so you might want to temporarily bypass the switch with a paper clip in the connector to see if that is keeeping the pump from running.

Have you checked for battery power and ground at the fuel pump? You could have a blown fuse - especially if your old pump was shorted.

unplug feul pump at tank and see if fuse still blows , if not then replace feul pump and if yes the look for short.

Check this 3 items in this order efi fuse, efi, relay, circuit open relay.all of them in the engine compartment's fuse box.

Check the fuel pump relay. Refer to the owners manual for it's location.

The crank sensor is what pulses the ijectors,and makes the spark,so I would start at the crank sensor.Let me know how you come out.Check for any blown fuses also.Ecm fuse would cause this,but it may be called anything ,so check all fuses.

If there is no power to the fuse block then there has to be a main relay check that to see if it is blown. it is usualy located in the fuse block undr the hood.
