2004 ford explorer when you turn the switch on the fuel pump fuse blows . i un pluged fuel pump it still blows . i went and un pluged fuel control module and it doest blow


Unplugging the fuel control relay or module will ensure no current is entering the wire heading towards the fuel pump. The likelihood is there is a short circuit somewhere along that part of the circuit though it is possible the relay could be faulty.

Ideally, with the aid of a circuit diagram, the wire should be traced from the source at the fuel pump module along its length until the fault is discovered. There is intelligent equipment available that can locate short circuits.

Did you check fuel pump electrical circuit ? Look at a wiring diagram to see what all is involved in making the fuel pump work. No , the knock sensor can't cause this ! Do you know how to do automotive electrical circuit testing using a DVOM - digital volt ohm meter ? How to read an use a wiring diagram to pin point areas for testing in a electrical circuit ! What do you think makes that fuel pump work ? AIR !!!! Looking at a wiring diagram I see a fuel pump relay that gets B+ voltage from the engine control relay. The engine computer energizes both, relays .There is a fuel pump resistor inline before the fuel pump.
Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on engine then under subsystem click fuel controls ! Click the search button then the second blue link . The second diagram down shows the fuel pump electrical circuit .

Fuel pump and filter appears to be clogged no fuel getting to the eingein


Be very safe when you work with fuel and electricity. Only work with live wires when you are trying to measure their voltage. If fuel leaks then don't work with it until all the fuel vapor is gone. The first to do when you work on a vehicle is to disconnect the negative terminal on the battery.

There must be 12V to the pump for it to pump. If power is to the pump and the pump does not run then the fuel pump and fuel filter need to be replace. If no 12 V is to the pump then you have an electrical problem. Sometimes the pump motor fails or a wire shorts to ground. Either of these can cause a fusable link to blow. If a fusable link is blown you should disconnect the wires to the fuel pump. Next replace the fusable link and if it blows right away then the wires are shorted to ground somewhere. If you now have 12 volts to the wires you disconnected then disconnect the negative terminal of the battery and connect the wires to the pump. With the battery connected and you get fuel pressure then the engine should start. If you get no fuel pressure then the pump needs to be replaced along with the fuel filter.

I hope this helps.

My fuse for the fuel pump keeps blowing. the fuel pump was replaced. it was intermitant now as soon as you put the fuse in it pops. Short in the wiring somewhere?


When the fuel pump is replaced, often the correct wiring harness needs to be spliced in. The original wiring harness was more than likely reused. It is very possible the wiring harness is the cause for the short. Other than that, check where the wires go from the fuel pump wiring harness to the connection to where they go back inside the car. Corrosion is often another problem.

Put in a new fuel pump car will run for awhile


either the pump has a short in it or you have a wire pinched somewhere. Unplug the pump. If the fuse does not blow then the shorts in the pump or wiring to it.

I have a short in the wires for the fuel pump keeps blowing fuses when you move wires connected to the relay just put in a new fuel pump thinking that was the problem. where can i get a wiring diagram to...


The problem may actually be in the fuel pump relay itself. The windings of the relay which create an electromagnetic field when energized, may be shorted and/or creating a high current draw, thus blowing the fuel pump fuse repeatedly.

I hope this helps! :)

I have a 96 cadillac sadan deville, and it keeping poping the fuel pump fuse. can u help


There is a short somewhere between the fuse and the fuel pump. The problem could be a short in the fuel pump itself. The only thing you can do that I can think of or what we would do is drop the fuel tank down low enough to unplug the wire to the fuel pump then see if it blows the fuse when you turn your key on. If it doesn't blow the fuse then the problem is probably in the fuel pump.

1992 Saturn SC Fuel Pump Problem


You need to get the schematic / wiring diagram . There is a junction block in the center console where the wiring is routed to the entire car. The contact on the power wire to the pump gets burned /dirty and becomes intermittant . It needs to be cleaned .This happened to me twice.
