2006 GMC Yukon Viper 5906v Remote Start

So it's been a while since I've installed any alarms or remote start systems (about 6 years ago I worked at a shop). I'll admit I've been out of the game for a while now. I'm installing a 5906v into a 2006 GMC Yukon Denali. I'm using an XK09 and after many failed attempts, I believe it is finally programmed and running the door locks, etc. I'm having trouble with the remote start. It will not crank the starter. I have cut the Yellow starter wire and used the green and violet wires from the brain. When I try to Remote start, it will turn on the ign and acc, but will not send voltage to the starter wires (green or violet). For the most part, I followed these instructions: https://www.the12volt.com/installbay/forum_posts.asp?tid=128571&tpn=1#639574 I'm guessing I have a wire or 2 wrong somewhere? Picture for further reference.

The Starter wire cut and wiring looks OK.  Here is a link to a Pictorial on this style vehicle :

Have you programmed the Viper to Auto Trans Mode?  Have you programmed the Viper to Tach Mode and successfully done a Tach Learn?

You could try the Viper Shutdown Diagnostics to see if it is logging an error.

Soldering is fun!

One problem might be those connectors, solder joints please. Look at your yellow tube connectors where you've cut the starter, you aren't crimping them properly. Those wires will pull out in no time.

Thanks for the quick replies. I have successfully programmed the viper into automatic mode, and have also learned the tach. I will check to see if it is maybe in "virtual tach" mode? When I Remote start from the remote, I have to shut it down myself either via remote or pressing the brake pedal. Otherwise it will "run" (never actually starting, just leaving the ign/acc on) until I shut it down/deactivate. I haven't let it sit that long, but I assume it would stay on the entire 12 minutes. I CAN start the car using the key still.

Shut down via brake pedal or remote is normal. Runs for the time you set in the programming.

I understand those, But it's not actually starting the car.

List what you've connected to where please.

And throw away the POS PK and use a DB-ALL2, you'd be amazed at how simple it then becomes.

I am using an XK09. Which I am thinking is the main issue I'm having. I cannot get it to program (again). Don't remember how I got it programmed the first time, but I tried to re-flash it again this morning, and now cannot get it to program at all. Called directed for some tech support and I cannot get tech support unless I'm an authorized dealer I might have to look at the DB-ALL2, maybe it's easier to program?
