2005 Ford F-150 5.4, 4x4 crew cab. No crank, no run

Asked by Frederick Aug 25, 2021 at 01:52 PM about the 2005 Ford F-150 Lariat SuperCab 4WD

Question type: Maintenance & Repair

I have a 2005 Ford F-150 5.4 crew cab 4x4. No crank no
run. When in the run position it has fast beeps like when the
door is open but much faster. I have checked all relays and
fuses and all are good. I have 12.4 at the battery and power
to the starter. I have reset the alarm system three times
and replaced fuel pump relay module on the rear axle. I am
up in the air about this. Not sure what to do. I have no
codes showing.
