I have a Hummer H2 with a LBZ drivetrain dropped in it and the motor would start up then turn off 2 sec later, it is acting just like the VATS is turning it off. So i disabled the VATS and nothing changed, still turns on then 2 sec later turns right back off.
This H2 does not have the BCM to go with the LBZ pcm, do i need the BCM as it works with the VATS? I thought just disabling the VATS would eliminate the need for the BCM.
Any input would help.
