Hi Guys

Anyone know where I can find a wiring diagram for my 2002 Astra 1.7 DTI 16v.

I can't get it started and I have traced an issue where the glow plugs aren't getting hot when the ignition is on. I have changed the controller but its still the same.

I have a Haynes manual but the glow plug circuitry doesn't appear in any of the diagrams.

Any ideas?
