I'm not sure of the exact model of my rs, but it is a 4 button compustar with the cm3000 brain. I had this installed in my nissan acouple of years ago- and I liked it so much that I took it out of my truck upon sale.

I am now trying to install it into my 99 GMC Jimmy. I have everything hooked up, all the dash lights fire up, the truck rolls over, then once it "fires" it shuts off. I have tried mulitpule sources for the tach signal, and it is presently on the pc,- pin 20 red plug. I had also tried it on the coil with no difference. I am aware of the immobilizer, however the unit will not start my truck even with the key in the ignition. I have double checked all my wiring, and even put in a new ground with no difference.

Any suggestions? Cuz I am stumped..................

Thanks

Think you have Passlock2 in that Jimmy. No transponder in the key. It's a resistor in the ignition cylinder. You would have to turn the key to ON but that defeats the purpose of the remote start test.

Soldering is fun!

ahhh, that certainly makes sense. I was under the impression that there was a chip in my key.

Guess not....thanks- off to get a bypass I suppose

Here is a link to a "relays & resistor" type bypass for the Passlock2 system : http://www.wiringinstructions.com/v2/diagrams200/238%20-%20General%20Motors%20Passlock%202%20Interface%20System.pdf
