Re: not start ing

how's your battery? Battery connections? Power to underhood fuse panel?

what does "nothing" mean? No dash lights, no power to any part of the vehicle? everything is ok but no engine cranking?

Re: GMC Sonoma not starting

Not a lot to the starting circuit for that year. make sure you have good ground to the engine. Power to the solenoid comes from the purple wire from the ignition switch through the neutral safety switch to the starter solenoid. Put a test light on the starter solenoid and see what it does when you turn the ignition switch to start. If the test light lights up then the signal from the ignition switch should be good. Verify the ground at the starter and if it is good then you probably have a bad starter. If the test light doesn't light up you will have to start working your way back up the purple wire to find out where you are loosing power. Ignition switch? neutral safety switch? Corrosion in a connection? Broken wire?
