If you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

2004 pt cruiser keeps blowing fuel pump fuse,replaced fuel pump, no change.runs rough at idle and stalls,blows fp fuse,also replaced ign.coil,plug wires and plugs also changed relays

There are two fuses for the fuel pump relay. One fuse is load side of relay, that fuse also sends voltage to load side of asd relay, the asd relay sends voltage to several systems, two of which are the fuel injectors and ignition coil. I'm not telling you to replace, anything, but, you need to do some testing.
The other fuse goes to control side of relay, smaller amp fuse. I don't know the amp rating of the fuse that keeps blowing.
See that fuse, it supplies voltage to load side of fuel pump relay and also to asd relay.

Fuse s under hood keeps blowing. It is the inj/coil fuse

Try jumping the starter with the key on. If it doesn't blow. Check the start wire for chafing and grounding out. You can pull the starter relay, Try to start it, see if it blows,yes, it is between the fuse panel and fuel pump. no. Put it in and pull the fuel pump relay. Start it. If it blows, then it is some where between the fuse panel and starter. If you have one of those intelligent fuse panels, it could be that also. You can have the codes read for it. But it takes a scanner, not a code reader.

I have 1999 Pontiac grand am, my fuel pump fuse blows out whenever the ignition switch is turned. Do anyone have any suggestions on the problem?

When you turn the key on, it sends power to a relay. On the back end of the relay would be the computer for the engine computer. Which controls the fuel pump. Basically telling the computer, I am requesting fuel. Since the fuse blows, the possibilities are a bad wire from the fuse to the relay. A bad relay. A bad wire from the relay to the computer. A bad computer. First pull relay in the panel,turn it on. If it doesn't blow the fuse, You have eliminated one wire. If it does, fix that wire. Then swap the relay with another in the panel, if it doesn't blow a fuse, replace the relay. If it does , then remove the two plugs from the computer(under the dash on the drivers side). If it still blows a fuse, fix the wire from the relay to the computer. If it doesn't blow the fuse. Replace the computer.

Fuse for fuel pump keeps blowing

Normally fuse blows off if more current passes through it than what it is designed for.

Probably it is worth checking what original fuel pump fuse amps requirements and have the same installed.

Also check the relay if there is a relay set for the fuel pump.

Good luck

Keeps blowing fuel pump fuse. Why?

This normally happens due to short in the wirings.Or if someone has connected a stereo or some other electrical contrivance to the wiring harness (bundle), either under the dash or under the hood.To confirm this unplug the fuel pump wiring connections and insert new fuse.Then start the car and see,if still the fuse blows then its a short in wiring.But if the fuse does not blows then its faulty fuel pump relay or faulty fuel pump itself.So first replace the fuel pump relay and see,if the fuel still blows then its faulty fuel pump.But if the fuse not blowing then relay was the faulty part.The fuel pump relay located on the fuse box under the hood.---------This troubleshooting tips will help you locate the fault and solve it.-------Thanks.Helpmech.

Hi I have a 2000 ford taurus that keeps blowing the fuel pump fuse.I have disconected the fuel pump wiring near the fuel tank and it still blows the fuse.All the relays seem to be ok.if anyone has any...

Follow the wires up from the fuel pump to the front of the car. You most likely have a wire that rubbed though its coating somewhere and is causing it to ground out on the frame and blow the fuse.

1990 ford festiva no power to fuel pump. replaced relays , fuel pump, checked safety shutoff. nothing .. ran hot wire to fuel pump and pump worked but car still not trying to start. got spark. now what

The pump should have a fuse in the fuse block. You need to check for power in the fuse block and you need to check power to the pump relay.

Sometimes there is a fusible link to the Relay. If you check the connector terminals for power where the Relay plugs in, you can determine if the fusible link has blown. You could have already replaced the bad parts and now need to restore power to the Relay.

EEC relay fuse keeps blowing id put a new fuse in the truck it would run for about 10 seconds then blow the fuse again.

There are 3 relays mounted below the fuse box .
The green I believe is fuel pump relay and the brown is EEC. The third relay is for the A/C WOT.
It is possible the wiring is shorted, check there, it is also possible you have a bad fuel pump.
Please let me know what you find.
