Hi My Mini stopped today for the second time symptoms - blows a fuse not sure what fuse feeds, engine stops and starter fails to turn over. Replace fuse, fuse does not blow imediately car sometimes will start and sometimes wont. When it won't start its like the immobiliser is not switching off with fob but you can hear a few clicks under bonnet when fob is pressed any ideas?
Has anyone got a fuse number list so I can find out what the fuse is for. Thanks Dave

Hi again the blowing fuse is the fuel pump fuse, however this doesn't explain why it won't actually turn over sometimes or un-immobilise itself. I suspect the relay module a trw unit 4 relay unit as this has the fuel pump relay as well as the starter relay, any one had problems with these?

Hi I took inertia relay off and shorted the two wires to bypass this. However I still have the same problem. I am being lent a YBW10022 relay block - engine management relays and I will see if this does anything. Also what does the immobiliser key fob trigger has it got a receiver in the ECU? As I wondered if this has an intermitent fault (I have put a new battery in fob). Dave

Hi Checked this it appears that I have an intermitant connection/wire brake fault from the alarm ecu to the engine ecu. As when I move the alarm ecu around I can cause or remove the fault, just need to find which wire or connection is faulty, homing in on the fault though. Cheers Dave
