I have a 1988 ford motor home, 460 motor, just cranks, I have replaced all fuel pumps, filters,distributor, plugs, ICM,engine starts then dies and only cranks, any suggestions
YES! I've run in to something similar with my '87. At the back of the motor - on top, behind the Intake manifold is the Oil Pressure Sender/Switch. There is another switch attached to the same "tree" that shuts the spark off in case of Low oil pressure. It's only 2 wires so you can short it with a paper clip and try it. Tell me if it works!
