can anyone guide me please.When i start my rodeo it purrs like a kitten but when i push the clutch in iit wants to die.And now i have no clue what it could be can some one please help me

The Clutch, Throw out Bearing, and the Pilot Bearing were replaced since this has started. There is no difference as far as Dying ou when the clutch is Engaged. Also the Timing Belt, Distrubitor Cap, Rotor, Wires and Plugs have been replaced. Still dyes out. The Slave Cylinder has just been Rebuilt and Clutch master Cylinder is still Pumping Good. I had spare parts for the distrubitor here at the house so I even tried that thinking that the Camshaft Sensor (part of the distrubitor assembly) might be bad. Still no luck. The PCM is pulling up Codes:
1.P0336- CKP range or performance problem
2.P0337- CKP low input
3.P0341- CMP range or performance problem
4.P0342- CMP low input

That is all the information that I know about the problem. I talked to the Dealership for Isuzu and they are about as dumb founded by the problem as I am.

maybe it's your sinchronizer in your clutch. Im not a mechanic or anything like that but thats what im guess.
