i just recently purchased a 2000 GMC sierra z71 and it has a DEI remote starter. when i press the buttons it will do its thing but the starter wont disengage so it shuts its self off. also i just figured out if my keys are in the on position and i the flip thru the gears when it hits nuetral it start up. is it posible the the power wire and remote wire are crossed? or is it another problem?
