"I have a 1987 Suburban 3/4 ton that starts okay when its cold, but yesterday after I an a short errand in cold weather, I get back in the truck and it wont even crank or click. I fooled around for 15-20 minutes checking fuses, then turned the wheel straight thinking maybe it was something in the ignition column wiring, and whammy, it cranks right up. Then, I drive it the 3 minutes back home, park it, and try to start it again. And Its dead again.\nI havent been out today to try it, but I wouldnt be surprised if it cranks.\n\n????\n\n The battery is strong, and the lights dim when I turn the key (which apparently shows the current hitting the solenoid).\n\nAfter doing a little research, Things seem to point to a few things:\n\n1. Starter Relay is acting up (at times??)\n2. Old wiring not giving starter enough juice to kick in (at times??)\n3. Hot-sticky starter that will have to rebuilt/replaced.\n4. Funky short in wiring in ignition wiring harness\n\nAny thoughts??"
