There is a high pitched sound coming from under my 2002 Jimmy. It seems to be originating in the vicinity of the fuel tank, catalytic converter, differential area. But I cannot isolate it. Possibles?


Fuel pump in the tank makes a high pitch sound which is normal. Turn your key in the ignition, but don't start, you should hear the high pitch sound with the pump priming the system. You will still hear it when started, it's annoying but normal. Different brands are quieter than other, I just replaced mine with a Delphi brand fuel pump which is a tad quieter than AC Delco stock pump.

This problem sounds intermittent. To ensure fuel pump is working, open fuel door and have an assistant turn on ignition switch to on position (NOT START POSITION) and listen for pump to make a whirling sound. Do this a few times after shutting switch off. Also, If you dont here pump whirling, you can spray starting fluid into air cleaner. If it starts , then its the pump

Whirling Noise


Sounds like fuel pump pressurizing the fuel system. They do that for 2-3 seconds and then it stops (for fuel injected vehicles).
