6.0 engine swap trouble
Looking for advice, information, anything to get my truck running. The situation goes like this, i have a 2004 with a 6.0 that the lpop failed so instead of rebuilding the engine in a truck that has just over 200k on it i got a used motor. It is also out of a 2004 truck but a slightly newer 2004. (old engine says 2003 on valve cover new one says 2004) Icp sensor went from back of engine to valve cover, no bridge across air intake, all things i wanted anyway. swap went well averything bolted up nicely. but now i have a crank no start. I CANNOT get this thing to fire. Ficm and pcm were used from old engine but new wiring harness that came with new engine. Ficm only fires injectors after short crank on started then ficm engages but does not seem to be sending fuel or firing injectors while cranking. Scanguage says voltages and pressures all checkout. also no codes are picked up.. kind of at my wits end with this. Please help.

Did you move the icp sensor wiring to the front? Did the engine you purchased run when removed? Did you bleed the fuel system properly? Is the fuel pump running?
FWIW, you need to go back over everything you did and recheck your work.
