2003 gmc envoy wont start everything lights up just wont crank and the ignition doesn't lock
I would check the following neutral safety switch, ignition switch, starter relay and starter
dont forget the cable ends being clean and tight to the battery and starter and block. then look for 12v during crank attempt measured at the start enable wire, the starter "S". what are those results. Were the cables clean, tight, well connected to a battery with 12.6v at least? Then, what is the condition of any cable that runs to the power distribution center and its fuses and relays?
