•The FICM uses CMPO (Camshaft Position Sensor Output) and CKPO (Crankshaft Position Sensor Output) signals, which are sent by the PCM, to calculate FICM SYNC. FICM SYNC is calculated by the FICM and is the correlation between the camshaft pin and the crankshaft triggers. Once FICM SYNC is achieved, the FICM uses engine speed, MFDES… Read More »
• No SYNC with an RPM signal typically is a faulty CMP sensor/circuit problem. • No SYNC and no RPM signal, typically is a faulty CKP sensor/circuit problem.
• SYNC is achieved when the PCM receives a signal from the Crankshaft sensor and Camshaft sensor indicating they are working and in time. If the Crankshaft and Camshaft sensors are working improperly, the PCM cannot calculate engine speed or cylinder position, preventing fuel delivery.
• NOTE: If there is no FICM logic power to the FICM, the injectors will still buzz once the key is cycled but the engine will not start. There will be no other symptoms related to a no start condition. • With the WDS, select DATALOGGER PID FICMLPWR.… Read More »
• The engine serial number is now located on the external crankcase breather. • The FICM has been relocated by the brake booster on the Econoline chassis.
• Oil fill tube adapter is now pointed to the front of the engine for accessibility. • The glow plug harness has been lengthened on the Econoline chassis to increase accessibility to the harness connector. • The location of the ICP sensor is the same as on the F-Series.
• The EP (exhaust pressure) sensor and tube have been repositioned to adapt for the chassis. • The GPCM bracket has been relocated to the left valve cover. • The GPCM, EP sensor, and power junction point all share a common stamped steel mounting bracket. The mounting… Read More »
• The fuel filter housing has been modified to accommodate the Econoline chassis. • The regulator has been repositioned to provide accessibility in chassis. • The fuel supply line now has a banjo bolt with two copper washers connecting it to the fuel filter housing.
• The oil line is routed down the right rear of the engine, staying clear of the IPR valve, and under the right side exhaust up-pipe. • The oil line enters the oil filter housing near the outside edge of the housing. Clean oil exits through the top, center … Read More »
