im in the service manual on like and this chapter is missing(sadly)
under dash some where; guess driver side.

Check the thermostat is operating correctly, the cooling fan is turning etc

first make sure the fuse is not blown for the fan, if anybody has ever tried to repair it before make sure the wiring is not backwards making the fan run backwards, try a coolant flush.

I am also working on a 2002 isuzu axiom with the 3.5 engine that also starts for a few seconds then shuts off and will not start back up i did an engine over haul on it, and the engine ran before i removed the engine, did you find the problem?

sounds like the thermostat is not opening up

Check this...

1. Remove the air inlet duct.
2. Drain the cooling system.
3. Remove the radiator outlet hose.
4. Remove the thermostat housing bolts.
5. Remove the thermostat from the water pump housing.
   

NOTE The O-ring seal is integral to the thermostat housing

If you follow the top radiator hose to a domed alumillium housing, it's in that housing.
