Hi everyone,

As a follow up on my earlier post (link below if anyone is bored), I ended up cleaning and tightening most of my 12v connections up front. While I had a few loose spots, it didn't solve the "hot starting" problem I was having. My friend who sold me (and occasionally works on) the GMC suggested it may be that the starter is getting too hot on the long drives (it was in the 100s throughout CA when I was there), and to let it rest. So on the trip home to Seattle from Los Angeles, I pretty much just kept it running at gas and rest stops, and once I plugged in at a camping stop, it would cold start fine (over and over).

So, now that I'm home I'm going to start seeing if I can narrow it down to whether my starter or starter solenoid is going. In the meantime, I wanted to start organizing and cleaning up the morass of wires I have in the front engine compartments. My boost solenoid looks like it has seen better days. In light of the prevailing community thoughts that the boost switch should be rarely, if ever used, my question is: Can I just eliminate the Boost Solenoid and not have it? Other than rendering the Boost switch useless, would that screw up anything else?

Aside: When I had the hot start problem again, I DID try the steering wheel movement and shifting maneuvers. I also got down and checked the wiring on the NSS. So I'm leaning to it not being NSS related.

Thanks.

P.S. Other than this hiccup, this was my first "long" trip without any major problems (2200 miles), including searing heat in Southern and Central California. I hope more trips go like this!!
