Viper Remote Start issue

I aslo hav ethe 791 and mine start and immediately goes dead. I was wondering if you could help me on mine since you got yours to work. If i turn the key on it will crank and run fine. Not sure if I have the right tach wire because I can't find the coil so i just hooked it to a gray/white wire from the cluster. Wonder if anyone knew. It' a 2003 Jeeep wrangler 2.4L thanks

what color is your key, grey or black? and for the tach, grab the grey at the coil or coil pack. to find it, follow the spark plugs to the coil pack, and there it is. look in each harness and AC test any grey wire you find in those harnesses. also you have one ign, and two accy wires.MECP certified installer

I would just take from the injectors then.  Take the wire that is not the same color on all the injectors and run the tach wire to that and learn it.  If you hear the fuel pump and the gauges come to life, then it cranks, and wont start then it is either pass lock or rpm's.  Do you have a bypass module for passlock?  If its passlock then the first time you start the car remote start after starting with the key the car should fire up, then die out, then when it retrys it won't fire at all.(it will run for a second or so off the gas that was allready in the lines)  I think the the theft light on the dash would blink too or something.
