    I was idling. One minute I was on high idle, turned it off when I moved the truck a couple feet and now it won't come back on. Any ideas?

    Most likely clutch switch or brake switch. Try bumping the clutch a few times and pull up on it. Same with the brake,and make sure the hand valve is all the way up.

    @062 that was, without question, the easiest fix I've ever had the pleasure of making. Stomped on both the clutch and brake pedals at least five times and all was good. I know there's a brake pedal piston that I should grease. Is there something similar associated with the clutch switch?
     
    Oxbow Thanks this.

    It would be best if you knew which one did the trick. Brake plunger and pivot pin needs cleaning and oiling.
    Clutch rods have heim joints,you may have a grease fitting on one of those.
    I use air tool oil and a eye dropper.
     
    spindrift and Oxbow Thank this.
