hi I have a transit motor home 2000-2006 model 2.4 diesel about 4 months ago it would not start it would crank but not fire up and the little red light for the immobiliser just flashers like mad , the garage repaired the fuel pump module , about 1 month later the same thing happened and the immobiliser code had tripped out of the module recoded and all ok ,I was advised to do something with the fuel pump so I had the pump totally reconditioned , yesterday same again , ant ideas on what would be the course of these problems ... thanks rob
