Problems with Fuel pump wiring
Hi.There's something wrong with the electrical wiring in my car - H3. The fuel pump gets power even when the key is turned off. Currently the fuel pump is burnt out due to this. Could you please advice, how to find a fault and solve the problem?

Fuel pump relay stuck open?
Drop the fuel tank and take a look at all the wiring there. You are going to have to drop the tank anyway to replace the fuel pump.
If the issue isn't in that location you will need to follow the wire loom looing for issues.
