Both fuel pump codes, have you checked fuel pressures? Does the car at times have an extended crank? Are the HPFPs noisy?

 

Pressure form tank fuel pump ok 4-5 psi.yes car does extended crank some times.

 

the problem was gone for a while because i changed gearbox.maybe is a gearbox slipping?

 

Does the pressure hold ok when the car sits? Most likely you have a regulator leaking down and causing loss of fuel pressure, which would set the codes and cause a long crank.

 

low fuel pressure ok high pressure not measured but turbo pressure falling down.but the way this problem only for 1-2-3-5 gear.sorry for bad englis

 

I'd check your fuel pressure at rest after the vehicle has been sitting and under full load, I'd suspect you have an issue with the low pressure fuel pump in the tank or the regulator, causing the low fuel pressure codes.
