unfortunately you have to take down the fuel tank- they sit inside the top of the tank. to answer your other question- if the fuel pumps are shot, the car wont run- shouldnt even start. make sure to check the fuel pump relay before going for the pump. its an easy check before you rip out the tank.
where are the fuel pump relays???
CHANGE YER OIL.
IN the tanks.
