All of a sudden, am having trouble starting my ’94 F-250 Diesel. Engine cranks, but it won’t fire. I’ve verified that fuel is getting pumped to the fuel filter/water separator, which I’ve drained (it’s new, so I don’t see how it can otherwise be clogged.) How/where else can I check for a problem beyond the fuel/water separator?
Do you have an engine light? Is it a late 94(powerstroke) it could be a cam sensor. Watch your tach when you crank and make sure it is moving up about 300 rpm.
