The fuel pump is shorting out and that is why the ecm fuse is blowing .Disconnect the the fuel pump and try it again,if the fuse blow's again then it is not the fuel pump.
Disconnect the harness at the fuel pump and replace the fuse. If your fuse doesn't blow after turning the ignition on, you probably have a bad fuel pump, check it for shorts.
More than likely the fuel pump is going bad. Also check for a clogged fuel filter which will cause the pump to overheat and blow the fuse.
It could be your fuel pump fuse or just your fuel pump. i had the same problem it was just the fuse on mine
Fuel pump has seized or wiring is shorted. Easiest fix?
Fuel pump is locked up. Replace it.
The fuel pump or the wiring is shorted to ground.
i just changed my fuel pump and it has not blown the fuse so i would say that it can cause the fuse to blow
Any wiring between the power feed i.e. fuse box and the pump
Yes. Bad wiring can make any fuse blow
Probably a bad fuel pump. Disconnect the wiring harness at the fuel pump and put in a new fuse. If it doesn't blow and you have 12 volts at the pump with the key on, replace the pump. If your fuse still blows, you have a short in the wiring somewhere.
Check to insure that you are replacing the fuse with the same fuse size and type (fast blow fuses don't substitute for slow blow.) If this is ok the either the pump relay or the pump is going bad and drawing too much power for the fuse to handle.
because is a fuse to protect other damaga
Not sure why blowing but if you can look in owners manual or chiltons to see what else is on the same circuit for example fuse #2 may have fuel pump and cigar lighter on the same circuit and if something metal falls into cigar lighter it will blow the fuse each time a new fuse is put in. Hope it helps. Also on my 1989 Chevy 2500 I had the same problem and I had a short in some wiring running along the driver side frame rail by the fuel filter.
Most likely causes are a wire shorted to ground and a bad fuel pump.
your fuel pump is either bad or the sock filter is cloged. When your fuel pump wears out it draws more current, it drags. solotion , replace fuel pump, do not use larger fuse , it could cause a fire. This is a common problem with all cars and trucks, when fuse starts to blow over and over replace worn out fuel pump. Hope this helps.
Overload? Excessive resistance (bad fuel pump)? Short to ground in one of the power wires? -------------- check your wiring to the fuse. ALso check your relays
That can happen when the starter has failed.
Either a bad fuel pump (most likely) or a short in the wiring somewhere. Suggest you disconnect the wiring from the fuel pump, put a new fuse in and see if it still blows. If no blow, bad fuel pump. Still blows, short in the wiring somewhere.
were is the fuse for the fuel pump
if you put in a new fuel pump and the fuse still blows check the fuel relay under the hood on the firewall,,its oval in shape,,,, disconect the relay and turn the engine over if the fuse doesnt blow then the relay is bad,,if it does then you have a short in the wire harness its easy to follow from the fuel pump to the relay good luck
It did on mine. When I went to check the pump, the fuse was blown. Replaced it and found that the pump was also bad.
A fuse blows if it is drawing more amps then the fuse is rated to handle, or if there is a short. I suspect your fuel pump is starting to develop a problem, BUT DON'T USE A HIGHER RATED FUSE BECAUSE YOU CAN CAUSE AN ELECTRICAL FIRE !
the fuel pump fuse
It's possible that the fuel pump has gone bad and draws too much current, blowing the fuse. Try disconnecting the electrical connection to the fuel pump, then replace the fuse. If the fuse doesn't blow, you should suspect the fuel pump. Even if that's not the problem, use a similar plan to go through the rest of the circuit to see what's causing the fuse to blow.
