04 ford f150. went to start truck today and it wont turn over. Ive done some research and it seems like the fuel pump driver module may be bad. However fuse 34 was pulled and is ok.....so can the module still be bad?

SCORGE

theft light flashing?

yes it is...i tried both keys also thinking one of the chips may have gone bad

gone postal

If it's the FPDM it will turn over, just won't start.

Try turning it on and letting it sit with the key on ignition on for a few minutes, they might re-pair.

If the theft light goes from rapid flashing to flashing every few seconds, you should be able to start it.

I'll give that a shot tomorrow. I just don't understand why both keys would act up? Like I said it won't crank. You can feel the relay click by the pasaamger door. I've been working on cars for most of my life and I don't think it's the starter....just frustrated.

When the key is off the light flashes normally. When you try to turn the key the odometer says check gauges and the light flashes rapidly.....but i will try letting it sit longer tomorrow.
