Hi, i left my 1998 bmw 328i parked for quite some time, eventually i got around to starting it, suddenly after 20mins the car shut down and never started since, ive tryed everything. can it be the key programme/ ecu.
Come on give us more information. Think if you were trying to fix your own problem and you had to explain the problem to someone else with exactly no knowledge of what's going on.
1st off....a key with bad electronics and reader will open the door and that's it.
So that being said does the key turn the engine? If so the key, the program and ecu are ok. Say the engine cranks but doesn't start. Fuel pump. unscrew the access plug on the fuel rail and see if any fuel squirts out. NO......don't ever do this when it's hot..........not that yours is because it doesn't run but I had to say that. The millisecond you turn your key over to get it to try to start...the fuel pump comes on and pressurizes the entire fuel system.
Got fuel pressure, the engine turns but still no start= ignition spark plug engine computer problems.
