Hello, What is the pressure? You could have sediment in the tank blocking the pickup tube, you may have an inline filter along the frame on the drivers side that could be pluggeg, or just the pump is going bad . Good luck !
A clogged Fuel filter or a failing fuel pump. Get it checked out if its making a loud sort of grinding noise than the pump is bad. The pump should have a humming sound that you have to listen for and it should only be audible if you go under by the gas tank while the car while its running.
