FIXED!!! OK, posting the fix for my issue for anybody else that might find this thread. Basically I had a bad computer (ECU). Replacing the ECU also fixed a couple of other things that I didn't realize were problems. Basic timeline: -For several years, the vehicle would be hard to start when...

Yep, that's exactly the problem I'm having. I have to cycle the ignition switch several times until the CEL and GEN light come on and then she'll fire right on up. Once started, she runs just fine and I can turn it off for a few min and restart without any issues so it kind of seems to be heat...

That's kind of what I'm thinking, but just wondering if there is a location that commonly causes issues. I found a way to test the ecm for high ground resistance but just wanted to make sure there isn't a common failure point that I'm unaware of. It seems like every problem I've ever had was...
