The fuel pump works when I hook a wire to the battery

Customer Question

The fuel pump works when I hook a wire to the battery terminals on the postive & negaitive & touch the fuel pump positive & negative. So are you saying to do the same thing to the fuse box and see if there is power to the fuel pump with key turned on?

You now need to check the circuit wiring from the fuel pump fuse to be sure that is good with no breaks or bad connections. If that circuit is good, then the computer can be bad. The easy way to check this is with a scan tool for powering up the fuel pump.

Thanks, Ron
