Truck will not start when it rains, New cap and rotor 3 times a year, Always has moisture when it rains and corrosion on the contact points. No mechanic or dealer can fix it. What should I do?

If you are using the aluminum contact cap and rotor switching to copper will help IMO.

I used Accel caps and rotors on my 93 V8.

Try a moisture displacement spray.

  Hopefully they get this issue sorted because the engine is pretty great otherwise.

  I would not recommend bakflip. My hinges broke and they don't sell replacements. If seems a hard fiberglass cover would be waterproof? Not as convenient though.

  I followed up on this thrust bearing issue and it appears this is a 2025-26 issue for the Duramax.

  New sensors installed today. They auto learned without issue. They were working within a 1/4 mile of leaving the installer. I think I'm done for now. Finally have everything done to get it to a good enough base level that hopefully I'll be happy with. Time will tell. I appreciate everyone's thoughts and opinions along the way.

  I may post it once I'm ready to send it down the road. It's very....recognizable. Documented, even. This isn't just any 1995 Blazer 😉 The feature it has is the only one I've ever seen in the wild. Not necessarily value-increasing, but it is rare. You are correct about the body; it's a Pacific Northwest (Wet side) vehicle since new so it has zero rust. It's straight. It was parked outside for a long time so it does show its age a little bit but otherwise presents very well and is very clean. If I didn't have guys on this forum wanting to hunt me down and kill me for my politics and sass, I'd post it up right now. 🤣 And there it is, adding some faux-intrigue about this weird little truck for those following the story.. I just returned from tearing the lower intake off a junkyard '95 2-door 4.3 CPI. $50 for the intake and $45 for the EGR still attached to it. I said to the guy, MY DUDE, it came attached, and probably doesn't work, and you're charging me 2/3 the cost of a brand new EGR, I know, I just bought one. Are you serious? He said if I didn't want the EGR I could go take it off. Alrighty then. So I took it off. My total with tax was $56 out the door.
