97 4.0 Jeep Wrangler Fuel Pumps


I am not recieving any power to the fuel pump. {pump was tested and was fine} Is there a shut-off or reset button somewhere on the vehicle? Thanks Mike


Yes. There is an inertia switch, which is meant to shut off the fuel pump in the event of a crash. If the switch has been tripped, or is bad, it will prevent the fuel pump from operating.

The owner’s manual should tell you where the switch is, and how to reset it.


Not sure what you have tested but I have found several late model Wranglers with non functioning fuel pumps caused by the deteriorated ground behind the parking brake pedal. Yes, that’s where the fuel pump was grounded, into the floor/firewall near the left bulkhead…
