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?
Based on experience could be one of several problems. Fuel gelling up if you experience cold weather without additive in fuel, not enough to get fuel to filter, engine requires high pressure (about 100psi) or might be a problem with bad glow plugs. Hope this helps
I would start with the injectors or the injector pump
If you didn’t prime the system after replacing the filter it will not start. Read your manual on the proper priming procedures.
did you bleed fuel system?
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.
ck th glow plugs and relay
