Except for the sender being stucked, what would cause that you can see 2 bars of fuel pressure (just like at iddle), engine not running, even after 48hrs.

Looks like it never drops

 

an extremely healty fuel pressure regulator, injectors, fuel lines and fuel pump

The system keeping it's pressure is a good thing, why are you worried? Does your fuel pressure move when you start the car? That would tell you if your gauge is wacked.

bonne chance.

 

Salut Cousin

It's just that before it used to hold the pressure for a few hours and then drop completely.

The next day I used to see no pressure before to start the car.

Also recently (it happened just once), I noticed that just after I started the pressure was only 1bar, and it stayed there until I gave a big accel in second gear. Then came back to normal.

 

if the car still seems to pull correctly, i would guess it is your gauge that is wacked. What brand is it?

 

Gauge is STRi X-Line (Electrical).

For now the car is pulling fair. Pressure is normal. Only once it was at 1kg/cm² until I clear the **** out flooring the gas pedal... then came back to normal.

I'll have my injectors checked and cleaned anyway.
