I had a very bad oil leak but today I got that almost completely fixed, many thanks to Guzzle for that. So I had the turbo pulled yesterday, and the fuel bowl out today. But when it was all back together it started up and drove fine.

I ran it for maybe two hrs today just driving around checking the oil leak, any time I shut it down it started right back up, I just went out now and it wont start, just cranks and cranks and cranks. Loose wire?? I looked everywhere. What else could I check?

 

The oil level in the HPOP?

 

That would make it not start? If the oil level in the truck is good, does that mean the oil in the HPOP is good?

 

If the level on the HPOP is to low it cannot develepe pressure no pressure means no start. There is a plug on top of it. The oils should be a minimum of 1" from the top.
The HPOP has a check valve that hold a supply of oil in there.

 

With lots of cranking and no start the oil level in the HPOP Res can drop. I think that the low pressure oil pump (lift pump) does not run unless the engine is running, but the HPOP is running oil to the injectors. Fill it up (turkey baster with a funnel on top works well) to within 1" to 3/4" from the top and try it out again. After filling the HPOP and if it still no starts, pull the IPR sensor and try to start it a fair amount again and see if that helps.

 

Fuel bowl heater shorted out???

 

Well im not exactly sure what did it. There was oil in the HPOP, the wires all looked good. It sat for about 7 hrs last night and when I got out there this morning she started right up. Thank you for your help!
