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.

I replaced the fuel pump in my 2004 dodge neon and it still keeps blowing the fuel pump fuse..as soon as i start it it blows..


There is a wire grounding out somewhere. Start from the fuel pump (u know that is good) and follow the wires inspecting them carefully for any chafing or corrosion. It should go up thru the floor around the back of the back seat. Pop the seat out and continue looking at the wires taking the wrapping off as you go. It may be bad under the carpet where water collects from boots and shoes, so look at these areas carefully for corrosion. Happy hunting!!

I have an 05 mazda 3 keeps blowing engine bar 1 fuse #35 in owners manual. replaced it once and car ran for ten min and died. now fuse pops instantly. is this a common problem? if so how do i fi


I had same problem with Nissan 4x4 took it done to auto elec he couldn,t find the short so he put in a resetting fuse so if it happened sometimes it would not blow fuse but reset, but that made no sense so after a month I worked out what was causing it.The alternator had a bear wire in side that touched other wires when driving over bumps so it was shorting out ignition and petrol pump fuse, so got another alternator from the wreakers and it never happened again apparently its common. seaya Neil

My 2004 dodge neon keeps blown the fuel pump fuse. can some one help


If it is working for a time and just blowing once in a while you probably need to replace the fuel pump. If it blows as soon as you put it in, then look for a short circuit in the fuel pump wiring.

Will not start and checked fuel pump no power to fuel pump i also have blown fuse for ecmb that blows as soon as i replace it


ECM B fuse supplies a constant 12v hot at all times to the VCM/PCM and to the fuel pump relay. The fuse is blowing telling you that there is a short to ground somewhere. Try this, take the fuel pump relay out and put a new fuse in. If it doesn't blow put the relay back in and if it blows then try a new relay. The relay may be shorted to ground internaly. Other wise you'll have to trace the wires to the VCM and the pump relay to look for a chafed wire that's contacting metal. The wire coming from the ECM B fuse is orange and has a splice in it going to the pump relay and the VCM/PCM.
Hope this helps.....Andrew

Fuel pump fuse keeps popping


You have a short to ground or the pump is starting to go bad. You can run a seperate wire from the hot side of the fuse to your pump to see if it is the pump or if you use an ohm meter to check the wire and the pump. Get's a little technical though.
