I rebuilt my Quadrajet on my 83 K30 350, new electric choke. PO had wire cut to choke, not hooked up. I hooked it back up to new choke, now choke light stays on. Choke doesn't open, I have 12V at the wire, but when its hooked on the choke, no voltage. Oil pressure gauge is also not working its pegged to the right. By reading past posts, is it a bad oil pressure switch causing it?
