my fiancees' best friend's boyfriend has a 90s suburban with a command start remote start from that similar era...he is having a problem with the starter not being able to disengage, but only when he uses the remote start...everything else works apparently (door locks and hatch pop), and his truck operates normally with the key itself and the starter doesnt stick open, but when he uses the remote start, the starter bendix will not disengage...

is this a common probelm? any ideas of what it may be? I havent personally looked at it yet, but my experience with remote starters is limited, and outside of DEI, it is almost nonexistant...

and ideas would be greatly appreciated...

thanks iin advance...

 I am not familiar with the way design tech made its starters that long a go, but  if they used a true tach starting, then the starter would engage until the RS saw the proper tach and then stop.  If it lost the tach signal or the connection was bad this might be the problem.

and if the vehicle didnt have a tach, what would be used as the signal to disengage the starter?

It would just be a timed start in that case.  Actually a lot of units just use a timed start even with the tach signal.  some units are right in the middle, they use the tach signal, but also a timer.

hrm...so then the timer is probably screwed in the brain itself and therefor essentially useless as a starter...are there any relays inline that could be at fault?

The Command Starts used a tach input for their remote starters from the beginning. Unless the Chevy is a desiel, then I would try tracing the WHITE or PURPLE / WHITE wire that is located by the ECM and make sure it is still connected. The Command Start will not operate correctly if the tach lockout feature has been engaged & the starter would stay engaged. You will need to relearn the tach signal to the unit.
