if you bumped the gas tank and it started and ran fine test the fuel pressure and volume sounds like a pump that will b going out soon

Thanks John, I did bump the tank and it did start, however it didn't run smoothly in fact it cut off soon after running kind of "sickly". So I'm guessing the fuel pump is out already, please advise.
