Thanks for your replies.
In answer to JuiceyV8 the starter does turn over
In answer to disco mike not sure what you mean by the injectors switching (bit of a novice i'm afraid)but can say that there is fuel there when you take the plugs out and a strong smell of petrol/ gas, depending on which i am trying to start it on from the exhaust.
And in answer to yoda-says the lights on my switch are green but they are all illuminated.
Once again thanks for your comments and time.
