It will even make this whirring sound when i am on over half a tank of fuel, i am beginning to think the bigger fuel pump is moving uneeded fuel around causing it to heat up and thats when i can hear the pump, it also has trouble starting up sometimes, i have found that if i turn the key and listen for the fuel pump and try start the car before the fuel pump finished pumping fuel it will start fine but if it finishes pumping then i attempt to start it will struggle and i usually need to give it some gas to help it start, which i shouldn't being an automatic transmission.
Im also thinking a fuel pressure regulator might fix this problem but what us everyones thoughts?
Really need some help on this guys?
