1991 towncar alarm

it is a crimestopper 900 remote start.i have it hooked up tachless,it runs with the key,I have installed many of these and I have never had this problem before!I know i have the right disarm wire because the security light on the dash goes out when that wire is negetive pulsed.

Assuming the unit is installed correctly, the problem is that tachless mode is not working, so you need to hook up the tach wire.J Rilla

Try to run the RS in tach mode the tach monitor may not be picking up the correct voltage from the tachless. Now when it runs and t5hen shuts it self off does the service engine light flash?"Big" Mike

remember to check all your wires with a dmm not a test light!!

I will try the tach method,the service engine light doe'snt come on when the engine shut's off.

Ok i would go with the tach mode then. If the service engine light would flash when it was trying to start you would have to find another factory disarm."Big" Mike

I hooked up the tach wire and it still didn't stay running,What I found is if I hit the unlock button on the remote the car will start but at a higher than normal idle,it will run for about 60 secnds then shut down,The unit restarts the car (up to 3 attemps on these models)and it's at normal idle and it stays running for the programed time.

What you have discribe here sounds like the proper tach RPM has not been recorded into the RS module. I would relearn the tach RPM, once the vehicle is fully warm, and in gear to drop the RPM to a nominal level. Regarding the tachless mode. If the RS is not wired directly to the battery for both power supplies. The voltage rise it expects to see, may not be recorded and thus the unit will not operate as expected.

Why would you do this??? I hope you also connected the ORANGE / BLACK (-) wire coming off of the RS-900 unit, to the OEM disarm wire which you have already indicated as finding.

The factory dis-arm wire is ORANGE / black!The car still doe's not start and stay running,I give up!

Did you just hook up the tach wire, or did you program the tach too? Do you have all necessary Ignition and accessory wires hooked up? Ign 1 BROWN / Pink Ign 2 Pink/Black Acc 1 BLACK/ Lt.Green I guess I am a litle confused becasue you said above that if you unlock the doors that the car will start and idle high, then after 60 seconds will shut down, then the unit will attempty to restart again and stay running? Is that right: it will stay running, but only after it has shut down once or twice first, and only if you unlock the doors first? ANy further deatiled information would be helpful.J Rilla
