You will need a scan tool so you can see the sensor voltages and communicate with the PCM. The 96 engine was out of an OBDII compliant vehicle and the 94 was out of an OBDI vehicle. The engine hasn't really changed but the sensors and their wiring has changed a bit. A scan tool with a good data stream will show you sensor values and will let you do tests on the systems. That is probably your best bet. My next question is is the MIL on? (engine light or service engine soon light).
