I've tried a couple of crank and cam sensors from a scrappy. I know these can be hit and miss but have also tested them with a multimeter and they are all working within the ranges that are advised in the Haynes manual.

I've had every fuse out, checked, cleaned and put back as it should be so no joy there.

I couldnt find any dodgey connections with the ECU. Any ideas of where they would normally break?
