So still having the starts then dies problem. Everything fuel related is now brand new and ruling that out now. Went over that in my previous posts. Checked ICM had 12volts and grounds well. Need to know what I need at ECM from it. Looks like white wire #9 at white. Changed out ICM and still starts then dies. Only code I have left. 1996 K1500 5.7

 

Update unplugged crankshaft sensor after clearing code and it doesn't come back.

 

So, code did not come back but the problem is still there?
