What does it mean if there is fuel in the gas tank but the fuel does not get to the engine?

This means there is either a fuel blockage in the fuel lines, a clogged fuel filter, or the pump needs replacing. Disconnect fuel line from filter on fuel-in side. then with an a hose and a rag, pressurize the fuel tank. the rag is used to block most of the tank filler hole,(don't let it fall in the tank). If the lines are clear, fuel will shoot out where you diconnected the line. Then reconnect the line and then disconnect the fuel out side fuel line. pressurize tank again. If no fuel, change filter and pressurize again. If you have fuel , reconnect fuel line and try to start engine. If the engine still is not getting fuel, this means the fuel pump is faulty. There is an electric fuel pump located in the gas tank. There is a fuse, a relay that sends power to the pump. The relay is energized by the engine control module. Just saying, that the pump may not be the problem.

have the fuel pump checked it's probably bad and needs to be replaced Clogged fuel filter, bad fuel pressure regulator, bad fuel pump relay. If when you first turn the key on(not start but just on, you should hear a humming for a second or so coming from the back of the vehicle, If you hear that, it means the fuel pump is running as it should to pressurize the fuel system.
