Hello all, long time reader first time poster. I've actually never had to post before because all of my questions have always been answered by searching. This is not my first remote starter install, but is my first that requires bypassing anti theft. Any and all help I can get will be greatly appreciated.
I have a 2003 Trailblazer. No factory alarm. No aftermarket immobilizer. Ive attempted to install a Prostart CT-3471TW remote starter with a ADS-AL CA idatalink bypass module. The bypass was flashed at the place i bought it with "ADS-AL-DL-GM1 5.0" firmware. All of my connections will be listed below, followed by links to the idatalink and prostart manuals. All connections are soldered.
My Dilemma:
When I push the start button for the remote start, all the warning lights, light up. The fuel pump turns on. The remote start box clicks, but the engine does not crank over (with or without the key in the ignition, in the off position). I can start the vehicle with the key, push the start button for the remote start, turn the key to off (and remove it), and the vehicle will stay running. The door lock and unlock feature doesn't work either with the aftermarket remote, but the factory keyless entry works fine. Also, I don't have the park lights or horn connected, as I am unsure which wires I should be using.
I also can not get the idatalink module to "sync" with the vehicle, in either data or hardwired mode. The LED just flashes letting me know what mode it is set to. It is wired for "type 3" installation as per the instruction manual.
I believe that my OBDII port is functioning correctly as I can connect my scan tool to it without issue.

I did install type 3.

Nope...firmware will be retained...you're just performing a reset...consider it a do over :)

Solder, tape, repeat!
What about the no crank issue? Shouldn't the truck still turn over but not fire or is cranking controlled by the bypass?

You are correct about the engine cranking without a good Passlock2 bypass. It should crank, Passlock2 just cuts off the
fuel supply. Due to the "no locks function" with the Prostart system, I decided to start with that issue first. Passlock2 is a
ignition cylinder resistor based system, so inserting the key into the ignition switch won't do anything for you. The key
would have to be turned to the ON position to supply the Passlock2 voltage and that would defeat to purpose because the
switch would power the ignition wires, too.
If the bypass module wasn't programmed to the vehicle, it wouldn't supply a Tach signal. You have the Prostart unit
connected to the bypasses Tach output. Did you get a successful Tach Learn with the Prostart?
I am not a Prostart user, so I'm not familiar with them. The manual shows "Shutdown Diagnostics". Connect the system
to the trucks Parking lights and see if that info points towards the no crank issue.

Soldering is fun!
Which wires do I use to connect the park lights? I did have the (-) park light output connected to the grey/black wire at the headlight switch, but it didn't do anything. I was of the understanding that was the best connection to make.

Verify that you used the correct gray/black wire as there are 2 of them. Use the one between the white and light green wires.

Thanks for the info guys. Got the lights and horn wired up and working. The no start issue was a faulty bypass. Exchanged it for a new one and everything works great.
Cheers!
