You have a short in the wiring to the fuel pump.. Go back and check all the wiring you touched. you may have not routed the wires at the tank correctly and they are shorted (crushed).. SINCE IT HAPPENS SOMETIMES.. I WOULD put in a new fuse turn on the key start the engine and look at the wires near the fuel pump and move them to see if you can create the short and find it. you will know when you find it because the engine will stop running as the fues blows. Don't take anything else apart till you cure the first problem. The very worst thing it can be is a short inside the tank at the pump. Post and let us know what you find.

    Hi just wondering even though it is the fuel injector fuse, is it possible that the wires from the tank can be responsible,just making sure you knew it wasnt the fuel pump fuse, its the injector fuse,im going to look asap. Thanks

The fuel pump fuse keeps blowing in my 92 grand am


So it is the injector fuse, not the pump fuse? The injector circuit must have a short in it, or an injector may have a short and be bad. Have your injectors tested with a "resistance test"-they do not have to be removed for this.If injectors test out good, you need to inspect the injector harness for bad wiring. Maybe you missed some of the melted wires?

1997 GMC Sierra, I keep blowing the ECM 1 fuse, I replaced Fuel Pump relay and Fuel Filter. Does the ECM 1 Fuse Pump the Fuel Pump, also disconnected the Fiter turned on the key and no fuel.


ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this

Fuse keeps blowing!


The fuel injection fuse should also power the injectors. If the fuse is blowing, I would think one of the injectors has shorted to ground.
Have you checked them ?

Fuel injector fuse is blown, keeps blowing. Engine turns but won't catch and start.


if the injector fuse is blown then the car won`t start as its not getting fuel into the motor to fire.if the fuse keeps blowing then you could have an injector/s that is drawing too much or the injector driver in the ecm may not be any good and needs replacing or a used ecm.it could be a short some where in the wiring for the injector system that is going to ground.

I have replaced the fuel pump on my 1994 pontiac grand prix with the 3.1 litre v6. But it does not seem to be sending the fuel to the motor? In the instructions it says something about the oil pressure...


Are you sure that the fuel pump is properly installed? Have you tested the fuel pump circuits to see if they are working properly? Did you also replace your fuel filter? (It could be totally clogged up) Have you checked to see if there is any fuel pressure at the fuel rail or are you just assuming that the pump is not delivering fuel to the injectors? Have you checked your fuel injector circuits for power and for injector pulse from the EngineControl Module? Have you scanned your Engine Control module to see if you possibly have a Crank Sensor or Cam Sensor problem?

The oil pressure switch only keeps the fuel pump running once the engine starts. The fuel pump should run for 2-3 seconds when you turn the ignition switch to the "Run" position to prime the injectors. The oil pressure switch is the problem only if the engine will not continue to run on its own after it starts up.

The fuel injector fuses keeps blowing as soon as i open the ignition switch, it dosent even give me time to turn on the car before it blows again. the car has a new fuel pump installed by jiffy lube about...


There is a short circuit to ground on one of the circuits that the fuse protects. I need more information about your car and exactly which fuse is blowing. (Year, Make, Model, Engine size) All of the circuits powered by that fuse must be traced to find exactly what is causing it to blow. Most of the components can be eliminated as the cause by unplugging them one at a time and checking the fuse connector with a test light. (Otherwise, you could go through a lot of fuses trying to figure it out.)
