Help! Truck dies after driving a few miles
Hello everybody! I am new to this site, new to the 6.0 world but have had 7.3's and even a cummins. I've heard too many horror stories so have always steered clear of the 6.0 until I got an offer I couldn't turn down. So anyway I got this truck a few weeks ago. Late 2004 F250 FX4. I was told it had an SCT tune, 175/30 injectors and a stage 2 KC turbo. I have confirmed I do have the stage 2 turbo as it was locked up when I got the truck so I rebuilt it. Got the truck running and took it for a drive. Made it about 4-5 miles and it acted like it was running out of fuel. Truck died and would not start again. (I had just put 10 gallons of diesel in it so that wasn't it) The night before after turbo was installed I let it run for about 15 minutes, drove down the street and back, parked in front of shop and noticed check engine light and noticed truck had a misfire. I killed it to pull codes and after that it wouldn't start. Charged battery overnight, got fuel the next morning and went for the drive. After a couple of hours of messing with the truck, checking fuel filters, checking codes again it still wouldn't start. I finally got it to run after turning battery charger over to jump start. It started then died, then started and ran fine.
I don't remember all the codes or their numbers. Had a few for oil temp sensor which was unplugged. Have several for EGR system but it has been deleted. Had another that was cylinder 1 contribution balance, so I definitely have at least some form of a fuel problem, but that shouldn't cause the truck to die.
Now this truck is supposed to be tuned, big injectors and big turbo, 5" exhaust. Turbo didn't spool until about 2,000+ rpms, no black smoke (which I don't care to see black smoke but with those mods there should've been some) I tried to powerbrake the truck and it wouldn't even break the tires loose on a dirt road (they are 35x12.50" tires though.) My 2002 7.3 with a 100hp hydra tune will currently run circles around the 6.0, so something isn't right. I probably got lied to on the injectors and the tune, but that's for another day.
Batteries are old so I'm buying some new ones today and going to check FICM voltage. Is there anything any of you guys have seen that sticks out that I should jump right to? I need to get this thing running right so I can either get rid of it or drive the crap out of it. Thanks in advance for any and all help!!!
