CAUTION: Refer to Cleaning Fuel System Parts.
CAUTION: To prevent pump/gear keyway from falling into gear housing, engine must be rotated until keyway is at 12 o'clock position (Placing Keyway at 12 O'clock Position). If gear retainer nut, washer or key drops into gear housing, cover may have to be removed to retrieve them before engine is started.
CAUTION: Whenever the fuel injection pump is removed from the engine, the pump drive gear is laying loose on the camshaft drive gear. Never attempt to crank or rotate the engine with the pump removed from the engine. Serious damage will occur.
The camshaft position sensor (CMP) is located below the fuel injection pump (CMP Location - Diesel). It is attached to the back of the timing gear cover housing.
