are you getting a spark?

remove a plug, rest it on the rocker and turn the engine over. does it spark?

if you are its all ok. likelyhood is not.

If the starter turns and the fuel pump primes then the immobiliser is at least partly working as these are both also controlled by the immobilser. It could still be faulty but you'll need an expert on the immobiliser to check it.

The coil is powered conventially (i.e. distributor and points), there is an ignition amlifier that is a fairly common failure item.

I presume you've checked that there are no loose connectors then I would check the distributor, has the rotor arm failed? all the HT leads firmly connected?

Do you have the Bible there is a section on ignition fault diagnosis.

Do you have +12v to coil +ve when the ignition is on?

If so, do you get a spark on the king lead when you briefly short the coil -ve terminal to earth?
