Battery cables appearing tight but really aren't is king with no crank issue on side post GM, yes check voltage drops. We do see some ignition switch issues. If it does it again, pull it into nuetral and the try it.
Years back, a friend of mine had a starter go out on his Toyota pickup. Went to Shucks (pre-O'Rielly) and bought one. It was a PITA to change. Didn't work, so he took it back and got another one. That one didn't work either. He took it back, refused a third one and got his money back. Went to NAPA and got a starter, and that one worked. Back around '82 I bought a rebuilt carburetor for my Chevy pickup from Shucks, and it was worse than the one I took off. DON"T BUY REBUILT PARTS AT SHUCKS!
