Recommended Procedure:
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
- Connect the diagnostic tool.
- Key on, engine off.
- Access and monitor the FUEL PW PID while cranking the engine.
No fuel command signal when the ICP, RPM and VPWR signals are correct usually indicates a loss of the CMP signal. GO to Pinpoint Test V .
A 5 MUEs to 2 ms fuel pulse width (FUEL PW) will be sent to the FICM if the system voltage is greater than 8 volts during cranking, engine cranking speed is above 100 RPM, injection control pressure is above 3.5 MPa (500 psi) and is in sync. Note that low fuel pressure or no glow plug operation could still be the cause of the No Start or Hard Start condition. A 0 ms fuel pulse width (a no fueling pulse) will be sent by the PCM when a sync pulse has not been received from the CMP sensor and if insufficient injection control pressure is present.
