yeah i figured it out today. it freakin jumped timing. Ive not even had the truck 2 weeks and and the motor was just rebuilt not sure why it jumped timing since everything is new but im now trying to see if the guy i bought it from is gonna do anything.

Did you get your truck running right? Mine had a problem where it acted like it was flooded but the only way to get it to start was to lay on the gas to pour air into the system. When it started it ran like it had 2 cylinders and popped and blew flames out of the tailpipe. I was told to unplug the coolant temp sensor and when I did it ran perfect. $15 part. You might try that just to see. It's on the front under the front of the fuel platform... there are 2 sensors and it's the one on the left I believe. Are you getting any codes off of it?
