recently bought 1.7 diesel corsa (isuzu engine) and have had problems starting it...now it will not start at all, the A.A. man has tried but it appears the immobiliser has shut down the fuel pump...could be faulty transponder... there are two solenoids on the fuel pump, is it possible to bypass the immobiliser? Apparently it is a common fault and a right pain in the a**e
go to fuel shut off valve at rear of pump,it may be hidden under a cover,there are two wires into the valve. live one wire and earth the other you should hear the valve click when you live it.find a permanant live (when ign turned on) use that as ur live and use engine as earth.
hope this helps.
