How do you jump the fuel pump?

Old thread, but I think so. The inertia switch is the "last stop" for voltage going to the pump. I would want to unplug the pump and verify 12V at the connector just to be sure though - but if you are jumping the connections as described above and still no pump then it's a pretty safe bet to replace.

when they switched from return to returnless around 00 or so the FP driver module is last in line... the inertia switch sends power to that, and that module in turn powers the pump...
