One of the things that could go wrong with the fuel system is the fuel pump relay, which works like a remote switch. It takes a small amount of amperage from the ignition switch to activate the relay, which then sends to the fuel pump the larger amount of amperage needed to activate the pump. You may also need to remove the relay so that you can relieve the pressure in the fuel system. If you remove the relay and crank the engine over a few times, fuel cannot get through the system, as the fuel pump will not be activated.
