The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.

SOURCE: fuel pump wiring diagram for 1998 chevy express

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump

I've run into new pumps that didn't work. If there is power at the pump and it is not pumping, then the pump should be replaced, again (under warranty).

No fuel getting to motor so no start. replaced pump fuses and relays all good. there is spark


you will need to check the plug to the pump on top of the tank. check for voltage. then if no volts trace the wires back. also you should check the relay have some one at the relay listening to see if it clicks when you turn the key. no click no volts no volts may be a warn out relay, if it buzzes change it.

Getting no fuel to the engine. some one zero out the computer. could not read the codes if any.


Fuel pump? If you don't hear it, you need to check if the pump has failed, or if there's a problem in the circuit to the pump. To check, pull off the fuel pump tank connector at the gas tank, and check for power on the fuel pump wire while a helper is cranking the engine over. If you have 12 volts there (can use a voltmeter or a test light), the pump has failed and need replacing. If no power when cranking engine, the fuel pump circuit will have to be diagnosed. You will need a wiring diagram of the pump circuit. It is a fused circuit, so first check the fuse. If fuse is good, find the fuel pump relay and hold a finger lightly on it while helper turns the key to on. The relay should click when key is turned to on. If it does, pull the relay out and check that the power feed for the pump is available on one terminal where the relay plugs in. Use the test light probe and check all terminals-one should be "hot at all times". If none have a signal (key is OFF), then power is lost between battery and that relay terminal. From here on, you will need a wiring diagram...Good luck.

Wiring diagram


Then the fuel pump has failed most likely. It is electric of course and located inside the fuel tank, the fuel tank must be removed in most cases to replace the fuel pump, and don't forget to replace the fuel filter

1982 Corvette fuse relay location and do you have to drop the gas tank to replace the fuel pump?


Yes, you need to remove tank.
There is a fuel pump test connector, either a single wire connector in engine compartment, left side, OR terminal G of the ALCL, the diagnostic test connector under the dash. Put battery voltage there and see if pump works.
Diagram also shows a fuse for the pump, probably in the dash's fusebox.The relay is probably is there also.

No fuel pressure asd&pump relays energized


The fuel pump relay won't energize if the ignition is bad, or the fuel safety cut out is bad. Don't know what Dodge uses. Ford has an inertial switch in trunk. Many cars use the alternator. Some use extra wires to the oil pressure sender. Try looking at the wiring diagram on relay side, and jumper the outputs where relay plugs into, bypassing the relay completely. The pump should hum and you should get pressure. If not, make sure the tank isn't buiding up vacuum, and make sure the power and gound are good at the pump.

Not getting power to the fuel pump. I have power at the relay but not at the connection on the pump


you may have a bad relay. use an ohmmeter to check for continuity to find where on the relay plug your wire feeding the fuel pump is. once you know which plug it is, use a jumper wire to provide power from the battery to that plug, then listen to see if the pump lturns on. if it does, then replace the relay. if it doesnt make a difference or you cant find that continuity between the relay plug and the fuel pump connector, then you mlust replace the wire that feeds power to the fuel pump from the relay.
