Question about 1993 Ford F250
Check for a crankshaft position sensor circuit being open, or the crankshaft position sensor is bad.
Try to spray starting fluid into the intake of the engine, and then if it starts for a few seconds, then it's a bad fuel delivery problem like a fuel pump or clogged fuel filter.
If the glow plugs aren't working then the Diesel won't fire up.
How old is the Diesel in the truck? Is it out of season?
Crankshaft Position (CP) Sensor OPERATION The CP sensor is mounted on the right front of some V8 engines, is a variable reluctance sensor triggered by a trigger pulse wheel (36 minus 1 tooth). Its purpose is to provide the PCM with an accurate ignition timing reference (when the piston reaches 10 degrees BTDC) and injector operation information (twice each crankshaft revolution). The crankshaft vibration damper is fitted with a 4 lobe pulse ring. As the crankshaft rotates, the pulse ring lobes interrupt the magnetic field at the tip of the CP sensor.
TESTING -crankshaft position sensor Using DVOM on the AC scale and set to monitor less than 5V, measure voltage between the sensor Cylinder Identification (CID) terminal and ground. The sensor is okay if the voltage reading varies more than 0.1V AC with the engine running at varying RPM.
