How to find the fuel pump relay location?
Check the computer if its properly grounded- The computer energizes the fuel pump relay then power goes to the inertia switch thru the brown wire then fuel pump. Here is the location of the fuel pump relay in the diagrams below.
Why is my fuel pump relay not working?
Check the brown wire that goes to the inertia switch then see if inertia switch has power on both sides it could be just a bad switch. It could also be a bad relay as well. If no power coming out of brown wire at relay try replacing it with a like relay and see if it works. It can also be a bad ground on fuel pump.
