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.

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 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.

2008 Ford F450 fuel pump relay fuse keeps blowing.


the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.
