Are you using the engine harness and computer from the 95 or the 2000? The difference is that the 95 is and obd1 and the 00 is an obd2. Do you have a check engine light on with the o2 sensor unplugged? The issue is that the 00 engine has more gizmos to lower emissions that the 95 didn't have and the 95 computer won't be able to run them. Also, I think the crank or camshaft position sensor is in a different spot on the obd2 motor. I'd need to look at a schematic, but you will need to get a computer and harness from an obd2 motor in order to run that motor.
