Apologies, I am a non-mechanic.
M3W carcooned over winter and not started (sorry, weather been rubbish).
Battery OK, can hear the fuel pump, plugs appear OK to me, topped up with fresh petrol (20% space left only) and finally tried one of these air inlet easy start sprays.
All I get is a rat-a-tat of the starter motor. Perhaps a very slight flicker after 5-10 seconds.
What next? Should I spray the plugs, replace, call a friend? Help
