2003 impala remote start issues

I have installed a compustar 600s along with the Fortin INSTL+ in a 2003 Impala and I can't get it to start. The lights come on in the dash and all I hear is the starter click one time. The unit then attempts this two more times. I have gone through the program process atleast 10 times with the same result. I am holding the program button on the bypass module and installing the black 4 wire plug. The led lights upcome solid. I then release the button and plug in the white plug. I then hold the lock the button on the remote while turning the key to on. The less flashes and I then start the car. The led then goes off. I can not get the car to run with the white wire at the coil connected to the yellow and black wire on the 600S. It missesto very badclean and dies when startingI with the key duringto programming. I have the orange and black wire from the INSTL+ connect to th yellow and black on the 600s though. All door lock and trunk release functions work fine. I do have the brake wire connected. All connections are soldered. I am thinking that the VATS is stopping the start process.and that is why it only clicks? Thanks

The phone auto corrected one of my sentences. The one stating that the car misses very bad with the white tach wire connected at the coil while starting with the key during program mode. Hopefully not too confusing. :-)

I have found the INT-SL+ tach output iffy.  You should only have the the CM600-s Yellow/Black Tach input wire connected

to either the Impala's coil wire or the INT-SL+'s tach output ( not both ).  The CM600-s comes set for Tachless Mode.  Did youchange Option 2-04 to Setting 2 and then do the Tach Learn process?

Soldering is fun!

The tachless mode on the CS600 sucks, which is why I won't use them.....but it's still a good troubleshooting tool. Keep the unit in tachless mode at least until you get the rest of the install figured out. I wouldn't leave it that way and put the car back together, no.....just use it temporarily to eliminate that as a possible source of trouble. Also, does the module light up when you activate the remote starter? It should, I think. If it doesn't, maybe your ground-when-running isn't hooked up right. Also, is the INTSL hardwired, or is it connected to the remote starter using the data cable that plugs in? If you're using the data cable, be aware that the CS600 only has one-way communication through data. That is, whatever it puts out (lock, unlock, trunk, et cetera) goes through the data cable like you'd expect. However, the CS600 does not "take in" anything through data. That is, anything that the INTSL sends out (tach, brake, door status, et cetera) still has to be hardwired to the corresponding inputs on the CS600; the CS600 will not "listen" to these things through data. This is detailed somewhere in the installation manual for the CS600, but it's easy to miss.

I will try all of your suggestions this morning. I have notthe changes option 2-04 to setting 2. The LED does light up when in start mode. Thanks for your help and I will update after while. The installation manual for the 600s sucks too. Lol

I have tried wiring without the data link and obtained the exact same results.  It will go into start mode and the starter will click one time.  I have a good ground connection and I cannot figure out what is going wrong here.  The manual states that the parking lights will flash if it fails to start but that is not so in my installation.  I have listed below my current connections along with a pic of the wires connected to the ignition harness.  I do not have the green or white wire soldered yet due to uncertainty of their placement.

4 wire harness to INSTL+ only has red connected to 12+ constant and the black wire is grounded.  The blue and white wires are not used.

Thanks

Here are the ignition connections.  Acc2 is not shown/powered and would require an additional relay.

Nice solder connections! 

Soldering is fun!

Looks like you had the Impala's IGN1 powered from the CM600-s as an Accessory wire.

Here are some more connections you didn't mention:

That fixed it! Thanks a million!!!
