THERE IS A SMALL SHREDER VALVE ON YOUR FUEL RAIL PUSH IT IN WHILE SOMEONE TURNS ON THE KEY. ( WATCH YOUR EYES) THEN LISTEN FOR FUEL PUMP RUNNING FOR APPROX 3 SECS. REMOVE GAS CAP AND PUT YOUR EAR TO THE FILL SPOUT.THESE ARE 2 GOOD TEST IF YOU DONT HAVE A FUEL GAUGE. YES IT COULD BE YOUR ALARM IF ITS CONNECTED TO YOUR FUEL SYSTEM,MOST ALARMS ARE CONNECTED TO YOUR STARTER CIRCUIT.
thank you
