I have a 2004 Pontiac Grand it keeps blow the ignition fuse now my dash and brake fuses blow! I use atuo door lock blows a fuse where do I start??

Remove the fuses to the circuits that blow. Then one at a time, install a fuse, turn any component on and see if it blows the fuse. Have you had an accident recently ? If so, maybe a wiring harness has been damaged and causing your problem.

You have a direct short to ground on that power feed circuit . You need to find a power distribution diagram to see what all gets is power from that fuse . Isolate the circuits till the fuse doesn't blow any more , then trace out that circuit that blows the fuse .

Ignition Switch RUN/ACC, RUN/START
Could be ignition switch problem , Chevy has had problems with them .

Can a cylynole switch cause fusses to be blow when ignition is turn on

If fuel pump is seized, you should be able to disconnect the hot wire from the pump, turn on the key and fuse stays in tact. My bet is on seized pump pulling too much current causing the fuse to blow.

Blown fuse pcm

It is possible that the fuel relay is faulty and causing excessive current through the pcm fuse which is blowing because of the excessive current draw to the relay.

Eng. controller Fuse keeps blowing when I turn the ignition on to start my car

Have you checked your wiring to starter? It sounds like the power wire going to starter has loosened up.That would cause fuse to blow and also the way you described that the car died. Or even check to see that the red wire going to starter hasn't gotten dinged or melted by the exhaust. Anything that would cause it to short out.

I have a 1986 Corvette that blows the 10amp fuse for the fuel pump. How can I determine the cause?

If the fuse blows after turning the ignition key to the "on" position you might try disconnecting the electrical connector to the fuel pump and turning the key to the "on" position. If the fuse still blows there is a short in the wiring to the fuel pump. If the fuse does not blow it is more than likely the fuel pump.

I keep blowing fuses from my fuel pump every time I turn the ignition on what could be the problem. Its a 1994 s-10 Blazer with vortec 4.3

OK, the fuel pump could be shorted out, or the wires to the fuel pump could be shorted causing the fuse to blow every time you turn the ignition on.

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.

94 chevy s10 blowing fuse

Chances are, you have a short somewhere in the wiring that is causing too much amperage to pass through the fuse causing it to blow. Use a decent voltmeter that will show opens and shorts to test continuity with the wires that run to the ignition.
