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, spark plugs are still good changed one coil. and still nothing.

thank you
kaye

 

Hi Kaye. Your no start problem could be caused by many things, so you'll need to start by getting it diagnosed. Will you be doing the diagnosis or will you be taking the car to a shop?

I would look at the basics first ... is the sufficient fuel in the tank, are you getting sufficient fuel pressure to the fuel rail? Your spark plugs may be good (good not defined), but are they firing? Are they firing at the right time?

How many miles are on the car?

 

i just checked the fuel rail pressure on the torque app. it indicates its at 82.7 psi
is that normal?

 

Was that reading with the engine running?

The high pressure fuel pump should produce 725 PSI at idle; reference is below.
