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 .

Which Ignition fuse ? Which fuse box is it in ? under hood , passenger compartment ?
IGN A
40A
Ignition Switch RUN, START, RUN/START/ACCY
IGN B
40A
Ignition Switch RUN/ACC, RUN/START
Could be ignition switch problem , Chevy has had problems with them .

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.

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.

98 Town and country won't stay running, ruse keeps blowing.


Keep installing a larger fuse & you will
someday burn a car to the ground
If a fuse blows once there is a reason
Replacing it one time seldom makes for a fix

Why does my efi fuse keeps popping 1999 chevy prizm


Pull the EFI relay, replace the fuse, and see if it blows when you turn the key on. If it does not turn the key off, reinstall the EFI relay and remove the circuit opening relay/fuel pump relay. Turn the key on. If the fuse blows than we know the problem is One of the O2 sensors, the IAC, the purge solenoid, or the ECM You can unplug the O2 sensors, iac, and purge solenoid. Replace the fuse, turn the key on, and plug them in one at a time until the fuse blows. Replace that component. If the fuse blows with those unplugged than its probaly the wiring and possibly the ECM. let me know what you find and I'll help you more if needed.

It seems that your blower motor is taking more load than rated and it blows the fuse.

30 amp fuse keeps blowing i was able to change it and it would start now it just blows at the turn of my key


If the 30 amp fuse blows there is fault or short within the igntion /fuel pump circuit. You need to check this case by ISOLATION. remove connection of the suspected sections one by one and confirm when the fuse blows as the particular circuit is connected.
