Hey guys, I finally finished installing a ProStart Alarm/remote start into my 99 Silverado NBS. I had everything working and I was testing it to make sure everything was working. After triggering the alarm with the shock sensor my truck won't start with the key or remote. I tried resetting the PassII (key on 10 min), tried resetting the truck (disconnected the battery for 10 min), Bypassing the starter kill, resetting the alarm. I've checked all the fuses etc and everything is good. There is still no crank.

 

Mine has has a "valet" swich. Sometimes when the alarm goes off, to get it 2 start I need 2 push in on the switchthen everything works fine. Don't know if you have one though.

 

Thanks, I tried that. I disconnected the alarm and traced the problem back to a faulty ignition switch.
