Gone, but not forgotten!
what y need to start the engine ?cluster??or y don`t need the cluster
the cluster is needed for run the engine???
what else i need to run the engine
All you need to start a genIII or genIV engine is the original wiring harness and the PCM. The PCM needs to have the VATS(vehicle anti-theft system) turned off. I take it that you want to put that engine into a different vehicle or you're going to strip it down to bare nothing for offroad use?
Sorry, didn't realize you are from Chile. English as a second language explains it. Don't feel bad, we have guys from Kentucky that can't form an intelligent sentence.

I'll try here... What you need to run the motor is a wiring harness, the PCM (engine computer) and the engine complete with sensors and fuel system. You do not need the instrument cluster or the BCM (computer below the column?).

Find someone with a tuner package for Generation 3 engines and ask them to turn it off. You can pay somebody to tune a PCM for you and they can turn off all the things you don't need turned on in your application. NelsonPerformance.com can send you a PCM to fill your needs, you just send him your old one in return. Allen Nelson can turn the emissions items off, the VATS, and calibrate the system for a speedometer for whatever size tires you need. He can do that for a very reasonable one time fee. You can re-use your steering column and ignition key, along with the body control module to let the engine start and run. You must have all those parts in order for it to continue to run. The BCM sends the signal to the PCM to start and continue running, otherwise it will only run for a couple seconds and then die. If you get the VATS turned off in the PCM you will not have to use the factory steering column and BCM.

i test the pcm of 1999 chevy truck in a2000 truck and didnīt work
the engine doesnīt start only the full pump and the engine crank

Don't know for sure, could be that the PCM would not recognise the signal coming from the BCM of the different year model.
