First check the fuel pump fuse in fuse panel in drivers' side end of dash. The relay is located behind the dash near the fuse panel, and is wired to that fuse. Pull the relay and see if it is the same as used by the fog lamps If they are the same, exchange your fuel pump relay for the fog lamp relay located under the cover of the fuse block near the air filter's location, and with the ignition key turned on, temporarily turn on the fogs. If they operate as normal, your fuel pump relay is good. It is your fuel pump electrical connections, or the pump itself that will be suspect, if the fuse and relay are good. A clogged fuel filter could prevent the fuel pump from sending fuel even if there is a signal from the PCM, just as a loose or broken wire could cause a loss of power to the fuel pump. Check those items too. The fuel filter should be replaced every 2years or 24000 miles, to achieve maximum life from the pump and fuel injectors. Sooner, if needed.
