Hello,
i have a 2008 mini cooper s r56. yesterday morning i started the car to warm up because its winter and its cold outside. I had to turn off the car and then when i came back a few seconds later to start the car, it wouldn't start. it turns over but it just wont fire! no warning lights!
battery is brand new, full tank of gas, spark plugs are still good and changed one coil. and still nothing.

thank you
kaye

 

check relays and fuses. also check the ground wire on the valve cover. get an obd reading even if there are no codes.

 

Did you ever find the problem? Could be fuel pump. I had the same issue and had to change my fuel pump.

 

Turns out it was the timing chain! The guide broke, the common mini cooper curse.
