    DTC P0215: FUEL INJECTION PUMP CONTROL CIRCUIT

    Monitor & Set Conditions

    Fuel injection pump operation is monitored with ignition on. DTC will set if no power is detected at the fuel injection pump controller with the ignition on.

    Possible Causes

    • Fuel Injection Pump Relay Ground Circuit Open
    • Fuel Injection Pump Relay
    • ECM Ground Circuit(s) Open
    • Fuel Injection Pump Relay Control Circuit Open
    • Fuel Injection Pump Relay Control Circuit Shorted To Ground
    • ECM

    Testing

    1. Turn ignition off. Remove fuel injection pump relay from Power Distribution Center (PDC). PDC is located at driver's side front corner of engine compartment. Fuel injection pump relay may also be referred to as fuel pump relay. Connect a 12-volt test light between battery voltage and cavity No. 85 (Black wire) in PDC for fuel pump relay. If test light illuminates brightly, go to next step. If test light does not illuminate brightly, repair open in Black wire between cavity No. 85 in PDC and ground connection. The ground connection is located on driver's side fender panel.

    2. Note which terminals on fuel pump relay correspond with cavities in PDC. Using DVOM, measure resistance between terminals on fuel pump relay that correspond with cavities No. 85 and 86 in PDC. If the resistance of fuel pump relay 40-100 ohms, go to next step. If resistance is not 40-100 ohms, replace fuel pump relay.

    3. Ensure ignition is off. Disconnect ECM harness connector. ECM is located on driver's side of the engine, just in front of fuel transfer pump and contains a 50-pin connector. Connect test light between battery voltage and terminals No. 30 and No. 49 (Black/Tan wires) on ECM harness connector. If test light illuminates brightly at both terminals, go to next step. If test light does not illuminate brightly at any terminal, repair open ground circuit on Black/Tan wire between ECM and ground connection. The ground connection is located at the ground connection for negative battery terminal.

    4. Ensure fuel pump relay is still removed from PDC and ECM harness connector is still disconnected. Using DVOM, measure resistance of Brown/White wire between cavity No. 86 in PDC for fuel pump relay and terminal No. 36 on ECM harness connector. If resistance is less than 10 ohms, go to next step. If resistance is 10 ohms or greater, repair open in Brown/White wire between PDC and ECM.

    5. Ensure fuel pump relay is still removed from PDC and ECM harness connector is still disconnected. Using DVOM, measure resistance between ground and cavity No. 86 (Brown/White wire) in PDC for fuel pump relay. If resistance is 100 ohms or greater, replace and program the ECM. See appropriate REMOVAL, OVERHAUL & INSTALLATION article. If resistance is less than 100 ohms, repair short to ground in Brown/White wire between PDC and ECM.
