Help with Codealarm RS - 2004 Saturn Vue

I've got a codealarm CA425 brain installed with the 535 remote start package. Having a problem that I just can't figure out, it's driving me nuts! The car will remote start fine one time. No SES or Security lights, I've done a resistor bypass to the VATS and have the keysense wire hooked up. After running for 1-2 minutes, it will shut off on it's own. After that, when I try to start it it just flashes the parking lights 3 times. And also when the alarm is armed the LED flashes 3 times instead of 1 like normal after this first start. If I pull power to the brain to reset it, it goes back to normal and will let me start it once agian. If I turn off the remote start with the brake pedal or remote before it turns off on it's own, I can restart it agian, one time.

I should add that I'm using tachless mode, I don't see how that could be a problem, but who knows?

More testing reveals: If I do this with the alarm armed, when the car shuts off it the alarm goes off. Then when I unlock/disarm it, it honks/flashes 4 times and the LED flashes 4 times. Agian it won't start remotely any more until I reset the brain.

Anyone?

Try hooking up a tach sense. Depending on whats under the hood, the tach may be easy to get to or may be a pain in the ass. Sounds like the starter is going into tach lockout. Also the vehicle is equipped with passlock 2 not vats. Be more specific on what you used and have done and I may be able to help you.John J. DiStefano Jr.

Well I hooked up the tach wire, it learned the tach signal fine, but it's still doing exactly the same thing. Anyone else have any ideas? This 3 flashes is some sort of an error code, just need to find out what it means. I guess I'll try calling code alarm tomorrow if i can get a few minutes free at work.
