Fix code P1233 Fuel Pump Driver Module off-line – Ford
- I put gas in it, but it has not started since the failure. My scanner reported a 1234 code, which is a Fuel Pump Driver Module (FPDM) offline code. I had difficulty finding the FPDM, but have now found it. It is located on the driver side, inside the trunk, near the Inertia switch but behind the trim panels.
- Dorman HD Solutions - 590-001: Fuel Pump Driver Module with Mounting Bolts. Original equipment fuel pump driver modules often corrode and fail. This NAPA Advantage replacement features newly designed bushings to reduce future corrosion and a reengineered microprocessor for greater reliability.
This codes sets if the fuel pump is not starting up properly. Two things can interfere with fuel pump startup—the fuel pump relay or the inertia switch. Start by checking the fuel pump fuse. Next, manually reset the intertia switch. If that doesn’t work, check for power at the fuel pump connector. If you’re not getting power, pull the fuel pump relay (or swap it with another relay with the same part number) or jumper the relay contacts to power the pump. If that still doesn’t work, check for power coming into the relay. If you have good power, re-jumper the relay contacts and check for power coming out of the fuse box and going to the fuel pump. If you’re still fighting a losing battle, check the wiring crimp connectors. Some techs report faulty factory crimps at the relay box.
