Default WTH was that? Fuel Pump Relay?

I just got home from a quick 30 minute ride and pulled the car into the garage.... I jumped out, but wanted to pull the car up a little more - so jumped back in and turned the key to the on position, but did not start it...

Fuel pump primed as usual, but then i heard this wierd humming from under the hood, and the fuel pump decided to Prime again, and again, and again... I turned the key off and the humming was still under the hood but once i pop'd the hood, the humming went away.

i can only assume this was the fuel pump relay sticking or something - anyone have other insite?

Thanks

The thing that concerns me is the fuel pump kept priming without the car actually running - it will typically only do this ONCE, it did it at least 4 times before i finally turned the car off..

I think it is the FP relay.

I have a FP gauge, and each time i heard the pump come on, it would spike the pressure - definitly the fuel pump priming..

I just changed out the relay with the airpump relay - hopefully that wont happen again.
