First things first, has it got fuel?
Does it crank at normal speed?

It's got fuel. Cranks at normal speed. There isnt a spark on any cylinder am I right in thinking if it's an immobilized issue I won't get fuel in the fuel rail?

Yes I think the immobiliser cuts the fuel too. One of the other things that will give no spark AND no fuel is crank sensor, but of the two I'd consider immobiliser hot favourite. Check the contacts on the antenna ring and clean thoroughly, and perhaps use a different key, if you have one?

That's what I thought so I've ruled out the immobiliser as I'm getting fuel to the fuel rail

Yes, but are the injectors firing? I think this is what is inhibited, rather than raw fuel pressure. Certainly is in the case of duff crank sensor, probably same for immobiliser.

I tested crank sensor it is all good. Cam shaft sensor is reading 3M ohms saying to me it has failed all though I can't find readings of what it's supposed to be
