2009 prostar isx crankshaft sensor issue

[Zmcd]

My truck has been at a shop for 5 weeks now. A different shop, not the one that drilled the crank sensor out. After replacing the ecm, and engine harness the issue is gone. The truck runs normal as far as the motor goes. It runs smooth without erratic rpm changes. I’m now having a different issue I will make another post for. I know for a fact the tone ring is damaged, I saw where it got drilled thru. Teeth are still there, just damaged or chipped at one corner. But truck seems to be running good now.
