GMC Sonoma, electrical shutdown

Written by: jfogelberg on Jun 06, 2007 06:53 PM

GMC sonoma won't start

Written by: g_haight on Apr 30, 2006 07:58 AM

After turning the key on and off several time it may start. The dealer can't find the problem thru diagnostics. I am thinking ignition switch, or netural start switch. Also the repair manual I have doesn't ... Read More...
