My car will not take a fuse, try to put one in and it blows automatically. I unplugged the fuel pump and ignition module and still hot. What could it be?

Good morning.

What is the fuse number so I can look up what it controls?

Can you verify the engine size?

Pull out the fuel pump relay and see if it still blows. Fuse 1 controls the fuel pump.

When I pull the fuel pump relay no fire goes to fuse number 1.

Okay, from there on, the only thing is the wiring to the fuel pump.

Remove the connector at the fuel pump and see if the fuse still fails. If it does, then you have a wiring issue between the fuse block and the fuel pump.

If it does not fail, you need a fuel pump.

I already have the fuel pump unplugged and it still blows fuse. I will check the wires from fuse box to fuel pump.
