Car started ok this morning. Got about 1/2 mile down the road and she died. Now refuses to start! Put key to position 2, all dash lights go out and then 3 amigos (but they are always on anyway!), ACE, rear susp lights and flashing M and S, water temp gauge goes back to the parked place and water temp light on. No sound from fuel pump. Engine will crank but not fire. Called out RAC and he could not get his computer and the car to talk to each other. Removed ECU and red plug was full of oil. Cleaned it with contact cleaner but no difference. 2000 Disco 2 TD5 in Swindon.
