Well I finally went ahead and purchased a M1009 - a 1986 with 49,000 miles. My boys and I are going to fix it up and treat it like a father and son project. In any event, we are going to start with the simple fluid/filter changes and progress from there.
The vehicle is in decent running/driving shape but does have a few querks that I am interested in chasing down before I feel it is ready for the road.
1. The vehicle idles nicely when first started (engine warm) but then idles high as soon as the throttle is touched the first time. The fast idle solenoid has power and is holding the throttle arm open. Is this normal on a warm engine? Is there a temperature switch that controls the operation of the fast idle solenoid and could it be bad, causing this issue?
2. The glow plugs don't always seem to work. The wait light sometimes comes on and stays on. After repeated key on attempts, the glow plugs usually work like they are supposed to. My plan is to replace all of the glow plugs and look at the switch and wiring as a start. What does everyone recommend using in terms of glow plugs?
3. The vehicle shifts are almost imperceptible but do occur. What would cause this? I am going to closely look at all of the vacuum lines and replace accordingly. Do the vacuum pumps typically go bad on these? Could the vacuum valve itself be bad or need adjusting? I would like to firm up the shifts when driving.
4. Lastly, I want to go through the fuel system from tank to injection pump and check the screen and all hoses. I also plan on replacing the mechanical lift pump and getting the injection pump rebuilt. Who do you recommend in terms of rebuilding the injection pump? Cost? Should I plan on replacing the injectors as well?
5. Mufflers are shot and need replacing. What does everyone recommend for replacements?
Sorry for all of the questions as I am sure you have covered these subjects in the past. We are just excited to learn about this vehicle and to start work. Your help will be greatly appreciated! If anyone has any parts available, feel free to reach out to me via PM.
Best Regards, Marc
