diagnostic test showed that the fuel pump is faulty. It was changed. The fuel rail pressure sensor was also changed.
The problem occurs sometimes when the vehicle sits for very long hours - engine not running and also during accelleration or crusing. The vehicle was serviced regularly.
Please note that the problem continued even after the fuel pump and fuel rail pressure sensor was changed.

Masterthere is no code for a bad fuel pump. there is one for the float sensor.
a code never identifies a failed part, just a failed system. you need to have a diag from a shop familiar with these repairs. i would not throw any more parts at it till you get it identified.Roy
