The fuel pump is probably in the gas tank. You can check if the pump works by turning the key to on without starting the engine. Open the fuel door and remove the gas cap. Put your ear up against the gas filler tube and listen for the fuel pump running. If you don't hear anything it is most likely a bad fuel pump. Let someone listen to make sure. To replace, you may have to remove the gas tank or maybe there is an access panel in the trunk, I don't know about a cadillac.

could be many things... first of all does the gm 100,000 warranty apply to a caddilac? second of all sounds like you have a fuel delievery problem. could be an intermident fuel pump or more commonly a bad fuel line. when it doesnt start can you hear the fuel pump turn on when you turn the key to the on position? also could be clogged injectors. hope this helps~

Check fuel pressure, and exhaust back pressure, Exhaust backpressure high would indicate restricted flow... probably restricted converter.
