I have a 1988 Isuzu Trooper II 4x4 with a 2.6L and about 150,000 miles. I can press the clutch and put it into gear, release the clutch and nothing happens. The truck doesn't move. Is the clutch gone out or is it something else? The trans. Still shifts smoothly and its like the clutch just will not disengage. Can you help? Thanks!
Do you have good hydraulic pressure at the clutch?
Look at the clutch fork (where the slave cylinder pushes) is it moving when clutch is depressed?
Feel fork is it loose? Can you move it around? Will it select gears (Engine running) with out clutch, but no drive? Please try and answer these so I can narrow down the fault.

The pressure feels a little weak the clutch is real easy to press. I'm not sure about the clutch fork, but it will select gears (with the engine running) without the clutch with no drive. Thanks Nick!

If you can select gears with the engine running with out depressing the clutch, there is no drive being transferred to the transmission. This could be the centre of the clutch plate has failed (or a major clutch failure) or a broken input shaft.

Thanks for the help! Sounds like this may be a little over my head and I may need to recruit some help on this project. Thanks for your time. Nick

Well Slicknick, I may be going out on a limb here but I have to ask. Did this happen after the 4wd was engaged? This was happening with my sons 98 Amigo. When it was put into 4wd the Shift On The Fly did not engage fully and locked up the front end differential. When that happened the differential twisted enough to make the pionion hit the clutch fork. Which made the fork ride down the drive shaft and engaged the clutch. Because the SOTF locked the front end I could not move the car at all and since the clutch fork was stuck behind the u-joint the clutch was still engaged. So I could choose any gear with ease but the car would not move. B. Hubs
