Hello.

I own a Mitsubishi RVR auto trans with 4g64 GDI.

My car totally has no power when there is load. Engine light will come on when load is felt and the car jerks and die.

Fault code found was: 56(forgot its 52,56 or other numbers) - Fuel pressure fail, which is obviously since car is thirst of fuel when there is load.

I replaced the fuel pump and strainer inside the tank but problem still exist.
I checked and clear the whole fuel hose system from tank to pump to engine.

Note: Car has sat on the yard for 3 years.

Any ideas ?
