GC 1995, How can you tell if the Fuel pump is bad? Also does the BCM have anything to do with the fuel pump? This has a 3.0L engine in it.

Fuel pump operation is controlled by the PCM. Can you hear the pump come on when the key is turned on but the engine is not started? The PCM will ground the relay for a couple seconds at this time to prime the system.
