Hello.

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

My car totally has no power when there is load or I constantly rev it when idle. Engine light will come on when load is felt and the car jerks.

Fault code found was: 56 - 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 ?

 

I'm sure people here would love to help, but Mitsubishi's ain't our specialty.

I would try a dedicated Mitsubishi forum if I were you. Good luck.
