If anyone has been following my mess of a truck, IAM now broke because of it. I just want to it to start thats all. I'm throwing a crank sensor P0335 code after clearing it. Truck will crank just fine just no spark. Have fuel as well. Have replaced every ignition part twice literally and everything is acdelco. PCM is brand new. I have power to everything including fuses. I have ohmed, voltage, probed, and light checked everything. Coil with light up but no flash.
​​​Expensive scanner still says no spark. Have tried everything. Can someone please help me.

Have you check the wiring harness going to the crank sensor for damage?

I have not took it all the way out of the entire loom. But I did a grounded check on the signal wire to see if it was grounded any where and it wasn't.
