2004 Trailblazer remote start

Using the Trilogic GMDL=BP with a Micro MASSTART 2001 as I normally do on newer GM Trucks. 2004 Trailblazer LT My wiring checks out fine. https://www.the12volt.com/installbay/forum_posts.asp?tid=39668 DIRECTWIRE™ WIRING INFORMATION - CHEVROLET / TRAILBLAZER / 2004 / Remote Start 12volts red (40A), RED / white (40A)   +   ignition harness Starter yellow   +   ignition harness Second Starter N/A        Ignition pink   +   ignition harness Second Ignition white   +   ignition harness Third Ignition N/A        Accessory orange   +   ignition harness Second Accessory brown   +   ignition harness Keysense lt. green   -   ign harn or BCM, tan plug, pin E3 Notes: The BCM is attached to the fuse box under the left rear seat.

The GMDL-BP is progrmed proerly and I have gone over it with Trilogic twice, Tried 2 different GMDL-BP's and 2 different Remote starts. What I'm not getting is the thing to start, or the Keyless entry to work consistently. The Ignitions 1&2 get 12v, the start gets 12v but nothing happens. Am I missing a wire from the ignition switch? I've connected to all the 10/12 ga wires from the switch under the column. Colors matched function listed above and at 12volts.com database.

I NEED the Brown accessory wire? I was going to try that... I will have the truck back soon. I Just didn't try that wire. I power it as an ACC wire Correct? or as a 3rd Ignition? Thanks for that Tip!

Second that.... Did get a 2005 Avalanche that I had to power up the second accessory though.... for some reason the traction control system didn't like not seeing it powered. Kinda wierd... first GM I've had to power that up in a long time. Gus Wherever I go, that is where I end up......

I didn't hit the brown wire on the Trailblazer either.  Been 10 months or so and have not seen it back either.

Are you saying it won't CRANK or it CRANKS but does not Start??

I use the GMDL-BP also.  I ususally tie the Brown ( Status ) wire into the THIN PINK wire on the Relay Pack on the START 2001Did you do TACH??How about Hood PIN?Hardly have a problem with the 2001 other then Transmitter lightsThis is how I Wire the START 2001 on the Trailblazer:

Constant 12 volts	RED (2)	IGNITION SWITCH HARNESS
Ignition 12 volts	PINK	IGNITION SWITCH HARNESS
Starter	YELLOW	IGNITION SWITCH HARNESS

Ignition #2	WHITE	IGNITION SWITCH HARNESS
Ignition #3	ORANGE	IGNITION SWITCH HARNESS
Accessory	BROWN	IGNITION SWITCH HARNESS
