Hi, I need help with a 2002 F350 that I recently purchased in non-working condition. The truck has 152K miles. And I don't know much about its history. The truck could have been sitting for a month or more. Here are the symptoms and what I have checked.
- The engine turns easily but won't fire.
- The glow plug relay has voltage across the inputs and 10+ volts across the outputs when activated.
- The high pressure oil reservoir was very low to empty of oil. I filled it to the top.
- The camshaft position sensor was broken and even somewhat melted at the tip
. How could this happen. I replaced it. The tach doesn't make a move when the engine turns with the starter. Would this still indicate something wrong with the cam sensor?
- The previous owner broke off one of the 3 bolts attaching the thermostat housing so it has no coolant. This of course needs to be fix but I was hoping to get it started first, run it for a few seconds without coolant, and then mess with extracting the busted bolt. I was expecting the engine would start without coolant. Is that a bad assumption?
Still won't fire even after extended cranking.
Any ideas of things to check?
My planned next steps are:
- pull the valve covers and check compression, replace glow plugs, and replace all injector o-rings. Doubt o-rings are the starting issue but while I'm there I might as well change them. I guess there is a chance that the prev owner ran it long without coolant, overheated it and warped the head giving me very low compression.
- if that doesn't fix it, attach a fitting and check the fuel pressure at the fuel filter.
I'd love to hear some additional ideas.
