welllike i said we have no info n vauxhalls we dont' h ave them in the u.s. but anyhow have your battery checked. it should read 12.4 volts at least with engine off then have it load tested. clean the terminals if it tests ok then check your starter relay and fuse it should be in your under hood fuse box. if it still won't startthe check your cablesbut you shold know a lot by the time you test what i've said. it cold be possible it's an ignition switch as well. one other thing don't let your mate touch your carunless you are giving him a ride lol......
