HELP! Truck won't start. Total mystery!!
Hello everybody. I am new to the forum. Please check out my problem.
Quick history: Truck in an 05 F250 6.0. I am the second owner and bought it January of 2012 with 68k miles on it. The previous owner did no towing, but would change the oil with coolant if he was the one doing it him self. 18 months later, the truck has 75k miles on it. I have deployed twice being that I am active duty.
The truck was lacking severe boost a few months back so I took the turbo out to see if the veins were sticking. Nope. The intake wheel was completely destroyed. I'm talking chunks missing from every blade and damage to the housing. It was a miracle the turbo even worked (boost worked normal about 50% of the time). Stock air box was fine, no dirt or pebbles in there so it was a mystery. Ended up sending the turbo out to Mad Turbo Werks and got a brand new one in with their upgraded billet 11 blade wheel.
While waiting, I did a Sinister full EGR delete. Got rid of the whole stock exhaust and got an MBRP straight pipe. Installed a brand new oil cooler and oil cooler screen, all new bolts O-rings, gaskets, intake gaskets, had the intake manifold and oil cooler housing washed in and out to the point of looking brand new, carbon free. Brand new K&N system. Full coolant flush, old oil out new oil in, new fuel and oil filters, and last the Sinister Coolant filtration system added. Truck is not leaking a drop.
So now after about 3 months of down time (mad turbo werks took awhile), the truck started up in about 5-7 cranks. Ran like a champ for ehh.. 4 seconds. tried to start again, and nothing. It turns over normally, but there is nothing there. My buddy is a certified Ford mechanic so he has been helping me. He said this is where I messed up. After I put the oil cooler screen in (drained the oil from the motor to look for debris), I didn't fill it back up. His dad who is a 30+ yr diesel mechanic said it sounds like 1 of 2 things: Either a spec of dirt not trapped by the oil went through the screen and punctured the IRP screen (I think that is what he said), or there is still air in the fuel lines and no oil pressure.
Hooked up a code reader, everything looks fine. Although after quite a bit of cranking to try and gain some oil pressure, the needle wouldn't even flinch.
Anybody have any ideas?!?! I don't have access to the socket to check the IPR and wouldn't even know whether or not it was bad. So I am ready to tow it to the Ford dealership. Just trying to avoid a grand in labor cost if there is a possible way to do it at home. Any insight will be appreciated. Thank you.
