How does the Mitsubishi Eclipse fuel pump work?
The Mitsubishi Eclipse fuel pump utilizes two check valves to control fuel pressure and correct fuel flow through the gas lines. Different recalls on the Eclipse affect the operation fuel pump check valve. Once the fuel pump check valves begin to have problems, different symptoms develop in the performance of the Eclipse engine.

Where is the fuel pump on a Mitsubishi?
On top of the filter housing is a small pump. Work the pump until it is hard and then try starting. If the start is now trouble free, air is entering the fuel system (possibly from the fuel filter) and the piping and connections will need to be checked.
Why is my fuel filter not working on my Mitsubishi?
Work the pump until it is hard and then try starting. If the start is now trouble free, air is entering the fuel system (possibly from the fuel filter) and the piping and connections will need to be checked. If there is no problem here, the fuel filter could be blocked and need replacement.
How to check for fuel delivery in a Mitsubishi Galant?
Relieve fuel system pressure in four-wheel drive Galant models by loosening the gas cap and undoing the harness connector to the fuel pump. Raise the Mitsubishi Galant if necessary. In all-wheel drive Galant models, disengage the wiring that connects the fuel tank and the fuel pump cover. Start the vehicle and let the engine run until it stalls.
