6.0 liter crank no start.
 

Could use a little input on a 04 6.0. Just put a remain engine in. Got it all together, primed the fuel system cranked forever like normal. Engine fired up for 10-15 seconds. Idled great then died. Never to start again. Cranks tyres to fire but can't. Blows a little black smoke out the exhaust. All readings seem to be in the range for this engine to fire. I'm beating my head against the wall. I'm having trouble finding what's wrong. Can anyone help me out?

Are u sure you have high pressure oil? Won't fire if not enough pressure. . Lotta air builds in system. Makes me wonder how they fire em up when new!

It has 1300 something psi and is demanding 1400 something psi.

Also burnt up 3 starters trying to get it started.

pm'd you:c:
