Wheres the reset switch for this truck
I put new fuel pump. And fpdm it still want start
There is no inertia switch, according to my wiring diagram. Any applicable trouble codes? Have you checked voltage and ground, anywhere? You can use a test light. Note the diagram for fuel pump relay. Can you unplug relay? The switch side of relay, is right side in the picture, terminal 3 hot all the time and fuse protected. If you can use jumper wire between terminal 3 and the terminal under it, in the picture, hopefully the pump will run. If it does run, the problem is on control side of relay, left side in the picture, the control side needs voltage and ground, top wire is voltage, goes hot with key on. The bottom on that side is ground.
