Your fuel lift pump is suspect. Fill the tank to full and if the problem improves, that might be it. The injection pump can provide some suction but uphill it will fail when the fuel pump is bad. A full tank provided pressure to push fuel to the injection pump. A half tank won’t. Also make...

Air is compressible. All gasses are. Air just liquifies at the wrong temp and pressure to be as efficient for a car compressor. When air gets into the system, the compressor won’t be able to liquify the mixture properly, so the system won’t work efficiently. When your system let go, air got...

Your vehicle was the slowest on the road, and your speedometer cable is what you’re blaming? I guess if that’s your story, you can go with it. 😝

Fastest and least damaging… drill out flat side other side. Annoying but simple. Other method would have been tack weld a bolt to other side and use ratchets both sides. not enough room for a cutoff wheel and Dremmel just too small. Thanks guys!

Darned buckets rotted. Worse, bushings are breaking and end nuts are frozen. Anyone know the best procedure for removing the frozen nuts from the hood? Or do I need to drill out/brute strength them?

Been busy. Had a hot second today to make a small change, but it’s the little things that make all the difference. Rusted lug nuts going away. New black ones from Amazon installed. Cleaned up the wheels nicely. Old bolts will get muriotic acid and black paint and will be recycled onto the M1025.

Double that amperage when selecting wires and relays and switches.

You should PM HummerH1

I’ve read the title of this thread three times, and I still think it could have been written by Bob Guccione. Tap power from batteries and use a relay. My strong suggestion.

Honestly, who cares? What is the purpose of all the guessing about Uncle Sam’s actions? They auction until it’s done. There are only 500,000 more to go.

Throttle position sensor is on the injection pump assembly

Nothing as good as cruising to “The World Famous Ramones”!!!! And yes, that song was and is about my home town. Thanks for the smile.

Start simple. Make sure you have enough radiator fluid and you don’t have a leak.

When I crawled under mine, I was able to reach them.

Parks Department built a new multimillion dollar off the grid modern looking building by the beach. My buddy and I decided to go for a drive. We decided we should figure out what this place was. Honestly, it is a super expensive public toilet with a few water fountains and office space. What I...

Loosen the injector hoses from underneath. Crawl under. Trust me.

Yes. And it is inferior to the HMMWV system. I own several HMMWV and I own my 1995 Hummer. I can say by experience that my HMMWV A0 through ECV REV A are universally superior. Temps when the fan is activated get lower in a flash. I can also use a switch to bypass the Cadillac valve to activate...

Respectfully. Not all injectors get stuck OPEN. This method I described is exactly how I found a plugged/closed injector that needed replacement.

As an explanation of Mogman post, you keep cracking injector fuel lines until you find the one that does not affect the cadence/tap. The bad injector line can’t push fuel through so loosening it can’t affect the engine rhythm.

Respectfully… 1-Military cooling upgrade kit requires pixie dust and Elvin magic. AMG woulda done it if it worked. 2-Unless your hydraulic system is missing or busted, nothing is wrong with the HMMWV cooling system as-is. That viscous system posted is only 80% maximal. Cannot lock up. It will...
