The VATS needs to be changed to "none" if you want it off.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Thanks, I tried that as well. Still will not crank. Any other ideas?
Cranking is the key lock cylinder and the BCM or starter problem. PCM only controls the fuel side of VATS. Turning VATS off in PCM will not fix no crank issue. Cranks, starts and runs for a few seconds then dies, turning off VATS in PCM fixes that.
Awesome, that's the kind of info I needed! Guess it's time to get out the test light again. Can any BCM programming be done here with hp tuner? Thank you again!!
No BCM programming with HPT.
