When I say the knock sensor isn't plugged in I mean it's fitted to the block, but there is no wiring plug on the loom to plug it in???

Well it clearly needs connecting, so something is amiss with the loom there. Are the plugs gapped correctly? (common error) though not my diagnosis.

I agree it should be plugged in, but again, it's ran fine before without it?
Further investigation is req'd tomorro

It probably didnt - it may have run better, but it wont run fine when thats not plugged in! It shares a mini loom with the ICV - so try to trace it back and you should see it - its a small black plug.

Low fuel pump pressure can also cause it to miss and run like crap, as I'm finding out at the mo,

Test it by running a perm live to the pump and building pressure up before starting it.

We've tried a s/h pump as the original pump did give up, there seems to be loads of pressure at the rail. Gonna have a full day on it tomorra and if it's still not fixed it will be broke for spares
How can ya check for bent valves without removing the head?
Has anyone else had a cam belt jump a couple of teeth? did it cause any damage or not?

my turbo was running funny, fault was some pieces of rust sitting on one injector inlet, rust from the tank but added a fuel filter now, and a new tank. Took the injector out and tapped it upside down and there was the piece of rust.

Well you'd never believe it, boost pipe from the intercooler had come off!
Refitted and it's back up and running now Still has no knock sensor connected yet either???
Thanks everyone for the help
