Have never owned a truck, let alone a diesel, but with all the Priusses out there felt a need to buy one. Here is the story: Bought a truck that needed "some engine work" Apparently, someone bought it from his company and it was serviced regularly. Then he put a new HPOP on it and never could get it started. I have a friend that put a new HPOP on his truck 2 weeks earlier and he thought he could get it running, so I bought it. It is a 2004 F350 4x4 6.0 Powerstroke. Here is what we did:
No Oil in oil filter at all. Had brand new oil filter that was clean. Aftermarket filter with tall cap. The oil tube in filter was missing button on top. Bought new OEM tube, filter and cap. Still no oil in filter. Read forum about LPOP pressure regulator. It was stuck. Fixed that. still no oil. Read forum on priming LPOP. Poured oil in filter housing with tube removed until oil started pouring out of pressure regulator. Now have oil pressure on dash and oil in filter. Engine turns over and it seems one of the cylinders is trying to fire. Read forum. Checked FICM. Fails buzz test. Took FICM home and resoldered connections. FICM now passes all tests and has 48V on Key cycle, KOEO and Start. After cranking a while, 3-4 cylinders seem to want to start. I don't know how long this truck has been sitting like that. How long do you think I have to crank it? My friend thinks there might be a problem with the stand tubes or dummy plugs. I read another post where someone suggested the IPR valve may be the problem. (clogged screen). I have a scan tool and just figured out I might be able to read the ICP pressure and IPR valve duty cycle. Am going to try that first thing in the morning. Any suggestions? I would appreciate the input.

 

I am having similar issues, It ran fine for me the other day to work then got back in it 30 minutes later, it cranks but wont turn over. I just got mine towed home so tonite I get to start my checking of all these things, I hope to be able to get it up soon, I am in need of the same advice, sorry to jack this thread too but hope to see if it has the same fix. I just replaced all fuel filters (had to get the sinister fuel filter cap since old one broke and notice it doesnt have the tab up top for the filter to snap into) got a new egr and oil cooler, changed the oil filter and cleaned the turbo and intake manifold.

 

Have you killed the batteries yet?? you should have, it takes ALOT of cranking to get the oil into the high pressure resivoir and then to get the air out of the High pressure system. It might take 10 cranks of 10 seconds /after you get the low pressure oil pumping/ space it out a little so the starter doesn't get too hot. It will normally kill fully charged batteries before it will start so make sure to have a good charger on it or even jumper cables to another truck. once you gt it started take it for a drive and get on it a little to help get the rest of the air out of the system.

 

Thanks Bobfbigman. Had the charger on it while cranking and yes, did crank till batteries were almost dead. They are brand new 875CCA batteries though. Had a feeling that it would start if I just kept going. Have not tried again. wanted to charge batteries good. It takes about 5 seconds of cranking before the gauge on the dash comes up. That is when it comes alive. Have not had a chance to try it again. Will try again tomorrow and let you know. Thanks

 

That is normal for the pressure guage, let us know how it works.

 

Sorry for getting back later. Did not have the charger plugged in, so batteries were still dead next morning. Starter burned up, so this morning I put a new one on. First time cranking, the truck fired up, but I was so surprised that I let go of the key, and after about a second she died. Lots of black smoke. Then tried to crank about 5 or 6 times more, but all she would do is try to crank. About 4 or 5 cylinders I would guess. ICP pressure is about 1000 PSI while cranking. (went up to 1500 when she first fired) and IPR is at about 38% duty cycle. Giving it a rest now, don't want to burn up new starter. Could this be stand pipes or leaking dummy plugs? About 80 degrees here this morning. Oil was probably a little thicker. Any Ideas? Thanks

 

Check your build date on the inside of the drivers door, if it is before 9/22/03 you don't have dummy plugs and those standpipes don't have the same issues as those trucks built after 9/22/03.

 

I'll have to check on that tomorrow. (Truck is at my friend's). It has the 4 screw FICM, so I think its probably after that. Any Ideas if it is after 9/22?
Thanks

 

could be a replacement FICm, where is the ICP sensor? if it is in the pass side valve cover then it is a late 04 and very well could be standpipes and dummy plugs as a cause. A air test will tell you if you have a High Pressure Leak somewhere.

 

Yes, ICP sensor is on passenger side at the front side of the valve cover. What is best way to do air test and can you use 125psi shop air for that? or is it just as easy to take valve cover off. Thanks
