You need to read the fault codes first, paperclip trick should work:-

The lack of rev counter suggests dead crank sensor to me.

I didn't think the paperclip trick worked on the facelift Vectras?

mmm ...not sure to be honest DD, I'm assuming the facelift still has the X20XEV +Simtec ECU combination as my '99 pre facelift, but maybe not.

Ah, now you mention that it's a diesel, don't bother trying the paperclip trick as that only works on petrol engined Vauxhalls. You'll need to get it hooked up toa diagnostic reader to have the fault code read out.

The reason for losing the rev counter is that it relies on a feed from the alternator. Not sure if the alternator belt on diesels has its own tensioner (it does on petrol engines) but it sounds like the alternator belt is either loose or worn; maybe both.

it has a metal cam belt

Its actually called a camchain.

not bad 8 post's in and we finnaly get the details sack the moderator i say lol

right the belt tensioner is self adjusting that said the belts get old and hard but the tensioners tend to wear also and tip slightly causeing the belts to fail the revcounter is read from the alternator so thats where you should start if it only starts to play up after a bit of a run then when its present (the fault ) then test the output of the alternator regards TB

you have two problems here squeek is due to belt or tensioner or both second is the rpm this comes from the injection pump on these (contrary to previous post) thats why you get a cam code come up, its built into the injection pump and is not changeable (sensor ! not pump) these pumps are notorius for failing have a search to see what i mean , Regards TB
