97 astro, remote start

The tach signal has to be programmed to the unit somehow after you've hooked the wire up. What you've described is a unit that hasn't learned the vehicle's tach or sensed a voltage change to know that the car's running. Most units I've done have had the tach programmed by starting the car with the key and then holding the valet switch until the status LED lights up. Some have dip switches that you can manually set for 1-cylinder, 2-cyl., 4-cyl., etc. I'm confident that your instructions will say something about programming the tach signal, or about selecting between tach sensing or voltage sensing, choosing crank time, and other programming options.C Renner's Auto Electronix

There is absolutely nothing for tach program or learn cycle no dip switches either, I guess once it sees signal it is supposed to be self learning??? or the signal just cancells the restart mode??

That would have to be a 12volt  source once started? maybe the drl relay?

others are in the manual, that is the quick reference page, unless you need all the step by step wire hook-up it is the same

Had someone with the same Unit & problem in a Pontiac about 6 months ago.  He tried to send me copies, but couldn't..................Guess I try and get a copy of a complete manual..............Seems kind of cheesie at best.Will try and locate more info..........MO
