Common problem with the ide engine is fuel pressure regs failing, even new ones have failed after a couple of weeks! Also the sensor and connections to it. The sensor terminals must match the colour terminals on the loom, some have silver some have gold. Also i have changed the odd pump. The regs are really poor quality even the new ones being supplied, as the vectra will probably use a similar reg. good luck with your diagnosis
