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.

so if im not getting correct pressure or volume does that mean i need a new fuel pump

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
