Hey to all. I have a 2004 5.4 Expedition that won't start. Wife came home and said her Expedition "feels like it doesn't want to go ". Later that day it wouldn't start. I checked for DTCs, none found. It would spin over but not start. It was spinning over slowly so I checked battery. It was bad (6 1/2 years old) so I replaced, thinking maybe the starter was pulling down the voltage so low that the PCM was not working. Still no start. Got 35psi fuel pressure.
Any ideas? Crankshaft position sensor? Camshaft sensor?
