P0230: Fuel Pump Primary Circuit Malfunction

2004 Ford Econoline E150, Van Cargo, 4.6 WSECTION P0230: Fuel Pump Primary Circuit Malfunction
P0230 - FUEL PUMP PRIMARY CIRCUIT MALFUNCTION

Description:  NOTE: For natural gas applications, the following description applies to the fuel shutoff valve (FSV) circuit. The PCM monitors the fuel pump (FP) circuit output from the PCM. The test fails if: with the FP output commanded ON (grounded), excessive current draw is detected on the FP circuit; or with the FP output commanded OFF, voltage is not detected on the FP circuit (the PCM expects to detect VPWR voltage coming through the fuel pump relay coil to the FP circuit).
Possible Causes: 
  • Open or shorted fuel pump (FP) circuit.
  • Open VPWR circuit to the fuel pump relay.
  • Damaged fuel pump relay.
  • Damaged PCM.
Diagnostic Aids: 
  • When the LFCF PID reads YES, a fault is currently present FPF.
  • An open circuit or short to ground can only be detected with the fuel pump commanded OFF.
  • A short to power can only be detected with the fuel pump commanded ON.
  • During the KOEO and KOER self-test, the fuel pump output command is cycled on and off.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
