crack injector lines 1,3,4 at the head and bump the starter but dont start. this will activate the lift pump for a 30 second run, when fuel comes out one of the lines tighten it and repeat process till these lines are primed...

Do you hear the lift pump run? When you had the lines cracked how good was the fuel flow? Get a scanner and pull the codes out of it, but you really need to know your fuel pressure... do you have access to a mechanical test gauge?

The lift pump sounded like it always does and my buddy that as helping me said it started squirting like a sob after the bubble stopped but it still won't start so were just taking it to a shop

sounds like the VP44 just bought the farm. I hope he's a good friend.
