SOURCE: fuel pump wont run and keep blowing a fuse in the front fuse box

The power wire to your fuel pump must be shorting out somewhere. Disconnect it and see if your fuse still blows. If not, then follow the wire all the way back to the fuel pump, and look for a bare spot. Good luck!

SOURCE: My ignition fuel starter fuse blows 2 to 3 times a day on my 98 dodge stratus!

sorry this is not going to make you happy but its a wire shorting out to the negative side of the battery it could be anywhere under the hood, look for any wire that look chaffed, hope this helps regards John

SOURCE: 01 chrysler sebring was running good but now keeps

something in the ignition circuit is drawing too much current.the starter draws 10 times that much current.check for shorted wires or a bad coil pack,or even the module,or a short in the distributor.get the wiring diagram.put a 25 watt bulb in the fuse instead,it will light and limit the current to 2 amps.disconnect items until the light goes out,and then check things on that power rail.

SOURCE: fuel injecter fuse blow imeditaly when ignition turn on

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.

I have a 1994 bonneville 3.8-i replaced my fuel pump recently, i keep having my fuel injector fuse blow, i took the injectors off and tested and cleaned them,the car seems to run real good


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.

How do you check to find which fuel injector is blowing your 15 amp fuel injection fuses?


Hi K Jones, I'm glad to help!

The only way other then checking the resistance of each Injector would be to unplug one Injector at a time until the fuse doesn't blow then you have found the bad injector. NOTE: Don't rule out a wiring issue grounding out on the engine somewhere because this happens a lot. Hope this helps and have an awesome day K.

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 ?

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

Trouble starting doesnt seem to want to fire


Check the fuses, I had one a while ago that kept blowing one of the ECM fuses. There are 2 ECM fuses one also sends power to the fuel pump too. Do you hear the fuel pump run when you turn the ignition switch to on? Just turn the key to the "on" position, not all the way to start, you should be able to hear the fuel pump run for about 3-5 seconds. I think it takes a 15 amp, I showed the owner which fuse it was and it would blow occasionally. One day it blew one right after another so he put a 30 amp in, he was out of 15's. I told him that was not a good idea. Anyway, that fixed it he drove it home and put a 15 amp fuse back in it, it's been good ever since.

I have a 2000 Hyundai Accent that keeps blowing the ECU 1 Fuse. I can change it one time and it will last for three weeks then before you know it I can change it 5 times in one day. What does the ECU 1...


The ECM1 fuse blowing usually indicates that the fuel pump wires shorted inside the tank. If you drop the tank and remove the module, you will probably find the insulation burned off the gray pump wire.
