Never assume "known good", especially where already running yourself in circles. If your pin outs check good with regard to the ICM, then obviously there's a problem there.

I wish I had a buck for everybody that ever told me "It can't be _____, because I just replaced it"

Even when _____was a new part, it's usually the problem....

Has anybody put a scanner on these vehicles and looked for cranking rpms, or checked the harness from the ckps to the icm, no cranking rpm indicates no ckps signal to the icm or pcm. I did not read all the posts as there are some add ons from the original.

so if i hook it up to a scanner again and check to see if it has cranking rpms that means the cranks sensor is working ok correct? i did check all the wires from icm to the computer a they all are fine. Grounds are all ok and fuses are all ok, it is a new crank sensor, and checked the balancer for and damage, did find one loose wire at the crack sensor but never made any difference when i replaced plug end.
