Engine Mechanical problem
1984 Other GMC Models V8 Two Wheel Drive Automatic 139000 miles
I have a 1984 GMC Caballero (GMC's version of the Chevy El Camino) and it fails to start. The timming was retarded and it had sat for four years with no care. The fuel is also four years old, I don't know what the problem could be and I don't know where I should start, what should I do.
