ok he was sat in a car park heater on engine running, and it dies on him, wont start again. at all. so bit of investigating thinks its the immoboliser, has the alarm and immoboliser removed ready for new one anyway, still wont start. has the relay changed for the fuel pump and vroooom it starts! goes down the road over a speed bump. STOP, dies again. wont start and everytime he turns on the ignition it blows the 30amp fuse for the engine managment (the fuse box under the bonnet. middle row at the end).
now hes well lost on wats wrong! any ideas?
thanx
