SOURCE: how to replace fuel pump on 2001 gmc pickup 3/4

the fuel pump is inside the fuel tank. some techs just lower the fuel tank down, others remove the bed. personaly dropping the tank is harder, but lifting off the bed requires about 4 strong people.

I don't have a diagram but I can tell you the pink wire going into the tank should be the sending unit for the gauge.

Where is the oil pressure sending unit on a 1987 gmc s15


  • You should have two of them (which went to one in think 1991 or 1992)

  • The sensor by the distributor is for the oil pressure gauge - see pic below.

  • The sensor by the oil filter worked with the fuel pump power circuit see - pic below.

My thermostat went bad on my 1987 GMC Jimmy S15 classic. We have changed the thermostat but the gauge still reads 260 degrees. Is there a reset button?


No there are no reset buttons on any of the guages. Does it read 260 always? if so try taqpping on it lightly and if it still is stuck, replace thye guage.

My fuel gage is pegged at the 3 oclock position (past full). how do i determine if it is the senidng unit at the tank or a dif problem?


Does the needle drop to zero when the ignition is off? If you can get to the sending unit disconnect at the tank disconnect it. If the gauge drops to zero the sender is bad, if not the wire to the gauge might be shorted somewhere.

Will 87 s15 2.8l throttle body sorta run if fuel pump bad? changed fuel filter it was totally cloged. fuel ran out line with filter off- key on. engine will run a little. dont wanna waste time and money on...


If the punp is bad it won't run at all. Check the throttle body injectors to see if fuel is coming out of both injectors. Sounds like one of the injectors is not working. If one is not working you can check to see if it is the injector or wiring by switching injector wires and see if the problem changed from one injector to the other.

I need to know how to rewire my wires going to my gas tank. My fuel gauge doesn't read right. When i fill it up it only goes to a quarter.


most lickly the sender itself is bad this very common on your model truck. does the low fuel light come on even when its full at every stop then read ok once you start moving again?
