Recommended Procedure

WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Install scan tool. Access FUEL PW PID on scan tool and monitor while cranking engine.

No fuel command signal when ICP, RPM and VPWR signals are correct usually indicates a loss of CMP/CKP sync signal. See TEST V: CAMSHAFT POSITION SENSOR under SYSTEM TESTS in SELF-DIAGNOSTICS - 6.0L DIESEL article for diagnosis.

A 1-6 mS fuel pulse width (FUEL PW) will be sent by the PCM to the FICM if system voltage does not go below 8 volts during cranking, engine cranking speed is above 100 RPM and injection control pressure is above 500 psi (3.5 mPa). Note that low fuel pressure or no glow plugs could still be the cause of the no-start or hard start condition. A 0.60-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. This 0.60-ms fuel pulse width will not allow injectors to be enabled, but does keep the FICM and PCM synchronized until sufficient injection control pressure is realized.
