wont start, vats disabled Got an 03 GMC sierra that will spin over but wont start. Only code showing was a security code for no fuel P1626. I disabled the vats through hptuners and still wont start. It has 55-60psi while cranking and has spark at the plugs(only checked 3 plugs). Plug fires at the same time as compression hits. Wont hit a lick on starting fluid. With a test light the injectors show to be firing. Any ideas what to do next? Think it may still be a fuel problem but no idea where to start checking. Also the key is hard to turn sometimes. Does disabling vats in the tune not get rid of all the problems associated with it?
