P1233 code Fuel Pump Drive Module disabled or off line
Customer: replied 8 months ago.
module is located drivers side rear trunk.
Expert:  James replied 8 months ago.
Hello, if you tap on the drive module with the handle of a screw driver will the vehicle run. Fuel pump driver modules are a common failure point on Ford fuel systems. They have dropped in price over the years for this very reason.
Customer: replied 8 months ago.
Tried that. Thinking next step check voltage to module through to fuel pump (and ground). I get 2 or 3 volts at the plugin at the rear of the Mustang. No sound from fuel pump when I turn the key on. Gets fuel to engine when I hot wire directly with 12 volts.
Expert:  James replied 8 months ago.
When you turn the key on you want to make sure you have 12v on pink wire with black wire. If you have power I would suspect bad driver module. If you don't have power I would check the inertia switch
Customer: replied 8 months ago.
Inertia switch fine. Will check the wires for correct voltage. Thank you. This is a retirement project. Vehicle was given to me by an international student whoe visa and passport were over due. Learning a lot. Did a 66 mustang two years ago for my son-in-law. Not so many sensors!!! Thanks. ***** on the right track now.
