Engine Mechanical problem
1984 Other GMC Models V8 Two Wheel Drive Automatic 140000 miles
I have checked the spark plugs, destributer, battery, Carb, pumped out the gas and added new super premium gas rated at 91 octane. And it won't start what is the problem? Also Should I try adding Lucas oil Fuel stabilizer which states that it can clean the fuel dilivery system? Basically what should I do next.
It is a 1984 GMC Caballero 5.0Liter 305 Chevy engine.
