easy blacstar it's my first swap ,

i got every thing but there is a problem ( i can't start the engine it's cranking but without really starting )

i tried reset the pcm so many times so any idea's ?

i changed spark plugs + new battery + cleaned up intake manifold & injectors ,

i have 2001 5.3 with harness + PCM i throw away my old engine with pcm in yard for now .. i know if send it to allen it will work like a charm but i live in saudi arabia that mean i have to send to him which will cost me a brand new one :/
