i guess it's .. i will upload some for you

i install my engine without looking on this :l ,

also about my engine harness ( new one ) do you guys have detailed pic's installation ?

[blacstar]

pics of a engine harness?

[BIG BLOCK 555]

yup

[blacstar]

yup

now your playing too many games, find a 99-2001 engine harness. It will be red/blue on the ends that plug into the pcm. keep the pcm thats in your truck. (send it to nelsonperformance.com) no more silly questions! if thats too hard, pay someone to do the swap for you

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 :/

at least you didn't waste 2 weeks chasing wild geese to find out your Wait4Me tune wasn't telling your coils to fire & have the tuner swearing up and down that you & 3 professional mechanics didn't hook something up right
