    I would suggest you have a mechanic check the fuel pressure. Even if the fuel pump is running, it doesn't mean your getting the correct pressure or volume.

    Yes you would need a new pump, unless when you got the pump out you saw something else that could cause that same problem. The only thing I could think of would be if the coupler (the small rubber connector hose) that couples the pump to the line was split. Hope this helps. Good Luck
