Hey guys im hoping you can help me, I have a 1990 gmc c1500 4.3l rcsb that wont turn over. Everything that should have 12v does, new starter and 5 batteries in the truck(i know, im a basshead lol) one day literally got home from driving all day, parked it, went back out a few hours later to run some errands and bam nothing. Im Totally lost. I saw the other similar thread where you guys recommended to check grounds and batts, alts and starter all having 12v and yes they do. Whats the next step?

do you have 12v going to the starter solenoid when the key is in the start postion? If not id look at a neutral/clutch safety switch ignition switch or broken wire going to the solenoid.
