don't think it is a fuel pump. could be bad plugs and wires, or the torque converteris bad making it stall.

This currently accord to my Pontiac if the car gauges move all the way then back and the car does not turn on this can mean that your fuel is not reaching the engine causing the car not to turn on. This might be due to a bad fuel pump or bad wiring when i myself changed the fuel pump it still was not functioning but when I had the wiring fix it started working been working for now 3months. So test the fuel pump before replacing it if it works then its the wiring. GOOD LUCK! :)
