you can test the relay with a fluke, or a test light to the circuit,if u have one ava. you can loosen the banjo bolt in the engine bay, and then check too see if you have fuel coming out when the ignition switch is on. If neither of those works you can jump the relay, or just drop the tank IAW the maunal, make sure you drain the tank. You can test the pump when you pull it out by connecting the leads to the appropriate connections on the battery. I you do drop the tank, change the filter like was said earlier, and clean the tank as much as possible.
