  1. I need a security wiring diagram for a 1995 GMC Jimmy. The battery has been removed for 4 weeks and now the vehicle will not start. I feel that the fuel has been cut off by the security system. Is that possible? If so, how can I over-ride the security system to get the Jimmy started.

  2. i have a 2011 gmc sierra. i didnt find a diagram for a 2011. i think the latest one i found was for a 2006. i was wondering if the 2006 diagram same as for a 2011. i am installing a viper 5902 with remote start. i was also wondering, my truck didnt come with a factory keyless entry but my doors automatically lock when put in gear, so is there another module that i might need?
