Actually 2004 Envoy. Had code for crank/cam sensor problem and wouldn't start. Changed both and then exchanged ignition switch with known good one. Now no start but no codes. Sprayed ether into intake.....no start either. Have to also disconnect battery since minor short kills it in couple of days.....probably not part of starting problem. Chk engine
