I'm Awesome
I had pulled the #1 plug and propped it up next to the brake booster so I could reach in the window and crank the truck and still see the plug. The spark was mostly orange, but a little blue between the electrodes on the plug. Seemed fairly strong, but I'm not a Chevy guy. My Volvo has run with less of a spark, so I assume it's ok, but assumptions are rarely good. Like when I assumed yesterday that my TPS was the problem.
I'm guessing there's a sensor or module of some sort that's causing my problems now. I just have to track it down. The crank sensor gave me some issues about 8k miles ago and it was replaced. Nice thing with that though was that it had a drivability issue, and gave me a code for the crank sensor. Swapped it, and the problem was solved.
My experience with other non-Chevy's has generally been that an ignition module will suddenly die, and the vehicle stops, while other electrical stuff generally goes bad over time and gives you a warning, even if it's a very short period of time. That's why my thought now is the module, but as I've mentioned, I know very little about the quirks of a Chevy.
Autozone has a Wells tester that can test the ignition module, so I'm going to check that out. That leads me to a question though....
I replaced the distributor about 2 years ago, and I recall there being a module in the distributor. What's that one, versus the one mounted next to the coil?
Thanks for posting the troubleshooting info. I'll go through it when I've got more time than a lunch break.
EDIT: I think I answered my own question. The module in the distributor is just the Hall sensor, right?
