2006 Chevrolet Trailblazer Remote Starter Tips...?

[aeronicapilot]

I'm installing a remote starter on my grandfather's 2006 Chevrolet Trailblazer. I've gotten the starter module installed and it works. I'm having a problem with the security bypass module though. I believe the vehicle has a Passlock II security system and I've wired the module according to the instructions. Still, the vehicle won't stay running. It will engage the starter and the engine will hit a few times before it dies. (Sounds like fuel starvation as that is what the Passlock II system interrupts). Has anyone installed a remote starter on a passlock II system? And advice, tips, etc.? Thanks.
I'm not worried about blowing it up, as I am very experienced in automotive repairwork. (I've replaced batteries in several of them without locking them up)Just not exactly sure how the security bypass module works.
I already have a bypass module. It's an aftermarket system by bulldog security
My grandfather bought it from carmax, and it has no warranty!
