This sounds like an electronic problem. the control unit thinks about 50000 cycles in a second. it's bound that there could be a problem. a second hand black box or computer box should fix your propblem. goodluck

I don't think there is a pump, it is done with engine oil pressure at the injector.

Mitsubishi Pajero Exceed 1997 Model Engine #6G74 GDI V6 3500,no power,I suspect its the engine control unit,I order the ECU,but still no power,probably its crankshaft and camshaft sensor.


I solve this problem with Mitshubishi Pajero GDI 6G74 like this: remove the two little filters from the high pressure pump and ,if necessary, insert a external gasoline filter.

97 Mitsubishi legnum,runs great but takes a bit to start, thought it might be fuel pump relay as you can,t hear pump start when key is turned on, is that normal for legnums.


Hi,
is your car a GDI engine? If it is GDI you can't really hear the pump working when you put ign on.
Give me some details and I might be able to guide you there.
Chassis, engine numbers, GDI ??

Car sputters when you accelerate


is the engine lite on? if a misfire shows, and the plugs are new, could be coil or wires. how does it idle? maybe air leak between mass air flow sensor and throttlebody.

Its located in the air filter housing....The volume air flow sensor also incorporates the barometric pressure sensor and the air intake sensor....If you are replacing either of these sensors replace the volume airflow sensor.......
