On Friday I had the Compustar Pro 2w9000fmr installed in my 2004 GMC Sierra 1500. The system works great and has some great range. Here is the problem that I am having. If the truck is running and I turn the key to acc the truck keeps running and after a couple of seconds I get a service 4wd indicator and a service abs light. I also noticed that when the truck is off and turn the the key to acc the auto lights and the dash lights come on. I didn't check but I am pretty sure that this means everything is powered up including the heater fan and other things. I can check this tomorrow morning. Does this mean that the acc wire and the ign. wire are wired wrong.

pretty sure I just did a 04 sierra the other day, there should be 2 ignition wires (pink and white) and both need to be powered or else I believe the issue you are having will pop up. one other thing I found to be very strange with that truck is that the second accessory wire (brown) tested as accessory but if it remote started it it would not stay running unless I hooked this wire up as a second igntion. anyone ever heard of this? Hope the info helps Jonathan

Thanks for the info. If if the problem is the second ign wire is it something the shop can do quickly?

all they should have to do is run a wire from the remote start brain and add in a relay to power up the second ignition. I would think maybe half an hour to 45 minutes maybe. depending on the person doing it and how easy it is to get access to the wires off the remstart brain. Jonathan

Yeah, I've heard of that too. Make sure both Ignition and both Acc. wires are hooked up. If not there can be a sevice soon light on or 4WD light on because no power is going to that circuit. Should be an easy fix like said before.

To become a Compustar Pro dealer... the shop MUST have qualified installers. Take it back to them and let them fix it. Should be simple! -------------

I stopped by the shop today and fixed the remote starter. It was the brown wire that you guys were talking about. Thank you for all of your help.

I am also having that same problem with the compustar pro on my 2007 GMC sierra classic. Also, if I start my truck with the remote, after i get in and activate everything it will periodically bottom out my fuel gauge for a few seconds then I get it back. Has anyone ever heard of this?? I am taking it back to the installer next week to get it looked at. He said he just needs to update the filmware in the unit and it should be good to go. I would like to get to the bottom of this before I make the trip to him (3hrs) so that I can prevent anymore trips in the future. Any advice that I could pass on to him would be apreciated.

The problem with mine was that only one accessory wire was connected. Once they connected it everything was fine.
