hi,
there is a black box on the back of the pump, which is held on with shear bolts and has three wires going to it.

You can break this black box box off, it can be a pig of a job, and behind this black box you will find a stop start solonoid, one of the 3 wires to the black box is an ignition live, connect this to the stop start solonoid. This bypasses the immobiliser and hopfully allows the engine to start.

Good luck Simon
