VATS and Fuel pump priming

[hoopstar]

Quick question: If VATS is still enabled on a vehicle without a BCM, will the fuel pump go through it's 2 second priming cycle or is the PCM essentially just 'dead' until it receives the expected BCM command?

im sure it still primes just doesn't fire the injectors.

VATS has nothing to do with fuel pump prime

the only security I've seen do that is the VP commodore, it wont enable the ecm until the security fob is pressed, but that's a car security system and not part of the ecm/vats

[vlad01]

All it is on the VP is the switched ignition is cut to the ECU by the ATM, so is not a true security feature, rather an elaborate kill switch.

[Holden202T]

regardless of how it works, it stops the fuel pump from priming is my message!

on latter models VT and up a SRS Module that has been deployed will cut the fuel pump, an oil pressure switch on older models can also cause issues.
