1999 Ford Expedition error code P0232

Engine Mechanical problem
1999 Ford Expedition V8 Four Wheel Drive Automatic 135000 miles

My 1999 Ford Expedition just stopped running. I started it up. It sort of "shook" as I backed it out of the garage. When I stepped on the gas, nothing happened.

It came up with an error code of P2032. The code says fuel pump secondary circut high. Is this a fuel pump problem, an injector problem or a computer problem? Or if none of the above, what kind of problem is it?

Do you
have the same problem?

Basically it's a fuel pump wiring problem.

30) Continuous Memory DTC P0232

If DTC P0230 is also present, go to step 40). If DTC P0232 is only DTC present, turn ignition on. Using scan tool, select FPM PID. Observe PID value for indication of fault while wiggling and bending FP PWR circuit between fuel pump relay and fuel pump. Fault will be indicated by FPM PID value changing to ON (indicating a short to power). Wiggle and bend FPM circuit between PCM and FP PWR circuit splice. Wiggle and bend fuel pump ground circuit. Lightly tap on fuel pump, IFS switch and fuel pump relay to simulate road shock. Check connectors for clean tight connection. If no faults are found, fault cannot be duplicated at this time. Go to TEST Z. If any fault is found, proceed as follows:
On all models except Pickup - F150 Lightning and Pickup Super-Duty models, isolate fault and repair as necessary.
On Pickup - F150 Lightning and "F" Super-Duty models, disconnect low speed fuel pump relay and note FPM PID value. If FPM PID consistently indicates ON, check fuel pump relay ground circuit resistor. See Fig. 160 or Fig. 161. Replace resistor as necessary. If resistor is okay, repair open circuit between low speed fuel pump relay and wiring harness splice. If FPM PID indicates OFF, isolate fault found performing wiggle test and repair as necessary.
