YES!!! The engine still works! I only made one mistake! I put the ignition live for the Fuel Pump Relay to a dead terminal rather than the relay. Once I had then hooked up another car to the battery to jump atart it as it was flat, and tightened a bad ground hey presto my loom still works without all the other stuff, including the immobiliser. I will wait till it's test fitted to the engine in the roadster before doing anything else to it. Time to put it in a box and forget about it happy in the knowledge it worked before I put it in the box and took the engine out!
