Hi there, my vectra 2.2 dti sometimes cut off when u push it from a low gear n cuts at around 3000rpm. i have read here a bit and it sound like that could be the High pressure fuel pump, is that right? how could i check this. i can push it in 1st/2nd without any problems n also i can get up to 80/90mph without any problems but will get there slowly lol

cheers rick
