2000 yukon, remote start

Installed a mars 22 RS all wires are correct.   Used a Omega gm databus bypass and it programed but every time i start the truck by RS it shuts down in 3 sec.  Security right  well even with the key in the ignition it still shuts down after 3 sec.  i tryed 2 bypasses and 2 RS units.  Im stumped anyone got any ideas

Check your tack setting and set it accordingly depwends where you got the signal from

it was tachless  voltage monitoring    i used.   i cant belive it makes that big of dif.  the truck  starts then dies 3 sec afterwards.  Even with the key in the cylnder.

so does the key matter thar i programed from as  the key i used was not orignal.

The key in the ignition in the run position but engine not running, Try and remote start it and it will more than likely start and  stay running. Or else try  start the car with the key and then hit start on the remote and then remove the keys and if engine stays running it is Passlock problem. Passlock ll does not have a chip in the key if the key turns in the tumbler it will work.

Thankyou

black and yellow on constant wire i was short of time.   ill hook it to white on the coil but i think its a bypass issue not  a tach prob myself.  Omegas smart tach is pretty reliable.   i had it on smart tach i tryed 2 units also .  I fell retarded cause the bypasses are so easy to program.

k so that will work though turning the key to the on position and hiting the RS?  dosent quite match what was said in the first place.

"That is passlock II the key in the cylinder has no effect,only when the key is turned to the start position"
