Great Forum Here! After my 97 Chevy Tahoe sat for 3 months, due to me installing a 6.5" lift kit, i jumped started the dead battery and the alarm works fine Except for the remote start. It tries to start but dies after 1/2 sec. Can anyone point me in the right direction.
Thanks a lot this website has givin me tons of info n ideas.
Thanks In Advance,
Patrick

you need to reprogram tach and maybe the other settings as well.

open a door on the car, locate your valet button. Next start the car and hold the valet button down within 5 seconds of starting the car. wait for your LED to turn solid blue and then your done. its that simple.

Also may need to reprogram any immobilizer bypasses you may be using as well.

The system may be setup to run tachless, which would be why the led never comes on. Was the system professionally installed?

Yeah the system was installed by a authorized dealer.
I guess a bypass overides the computer without the key in the ignition, so if the truck turns on and tries to start but can't it must be the fuel pump bypass that needs to be repogrammed. So with that being the case how would i do it?
Thanks,
Patrick

well if you read you manual or download one from this site you can find out what is shutting down the RS. You could also try starting the truck with a key in the ignition ( don't turn it on) and see if it starts, if it does you need to reprograms your bypass.

Simply putting a key in the ignition and trying to remote start it will not work on your truck as the required resistance that the computer needs to see is generated by the ignition switch, not the head of the key.
Your RS does not know the vehicle is running, this is why the starter is turning on when the vehicle is running with the key. Grab the installation manual from the downloads section of this site. Go to page 42 "System Features Learn Routine" and familiarize yourself with it. In the programming options section for menu #3, remote start features you will find feature 3-2 will put you into voltage sensing mode 3-5 will adjust the cranking time. Set your system into voltage sensing and set your crank time to 1 second. This should allow the pit-stop mode to operate properly and verify the starter is working properly.
To the fact that your truck does not start from the remote, as others have said it is probably your bypass module that needs to be reprogrammed. This will require a little work on your part, take down the dash panel under the steering column and find the bypass module, it is typically a small plastic box about 2" x 2" with wires running to the ignition harness or OBDII connector and to the brain of the remote start/alarm. Once you find that come back on here to the downloads section and see if you can find the installation manual for it. The manual will describe how to reprogram the module in detail. If you can not find the manual here, post the exact model number of the module and I am sure some one here will be able to tell you how to relearn the module to the vehicle. ------------- Installer, IT support, and FFL.

Thanks for letting me know about the download section, i've never seen it before. It would have been nice if my installation shop provided me with an install manuel for my alarm Well Twelvoltz i followed your advice and the pit stop option now works flawlessly. Thanks a lot. Now i just have to find some time between customers to take apartt the lower dash and find that bypass. Thanks Again, Patrick

One more thing, remote start works! I guess it was the voltage setting that was messed up. Thanks to all for their help. Thanks Twelvoltz for your detailed instructions! Patrick
