Check your spark plugs and compression, you may have a valve hanging open. Also check all your vacuum hoses/connections. They may be leaking

I replaced all of the vacuum lines. It will now start but still very low idle until I manually rev up at motor then it idles fine?
Clutch problem, I pushed in the clutch in and felt pressure the suddenly it was gone no pressure at all I cannot put into any gear. I can Barely start it in gear its like it drags. This is a hydraulic clutch. Can the master cylinder be bad. Can it be rebuilt?

This trooper has sat for two years without running. Everything worked fine when parked. When I 1st tried to start it, I pushed in the clutch there was presure then as I was pushing the pedal down I very suddenly lost pressure. If it was a cable and not hydraulic I would think the cable broke. I do not think the clutch is bad. How do I figure out if it the slave cyl or the master?

You will need a helper. It might be just air in the system as well. Get under the vehicle and have the helper push the clutch in. If it moves down there then it may be soemthing else like a broken release arm. You can have either system in your truck.
