Re: 04 mini cooper s won't start
If possible remove the intercooler and remove the fuel line. place a bottle over the fuel line and have someone turn on the key and see if fuel comes out. If fuel comes out I would check fuel pressure on the fuel rail. Set pressure 3.5 bar. if all checks out then try replacing injectors.

The starter is effected by heat. Does the motor spin just as fast when trying to start it when the motor is hot? If it cranks real slow it is the starter. If it cranks over at the same speed it is not the starter.
Get an account on a mini cooper forum and post the question there. you could also try a small spray of starting fluid into the air cleaner. If it starts and stalls then it is a fuel delivery issue. If it does not start then remove a spark plug and verify that there is a spark as the motor cranks over. Check for any blown fuses.
And you know the fuel filter is good? Could be injector problem: just as a check, spray some starting fluid into the intake and see if engine runs a few seconds. If it does, it is a fuel problem. Check injector fuse, as a start. Check fuel pressure. Check injector circuit. If engine won't start with starting fluid, check if you are getting spark. Problem may be in the ignition system.
Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..
Safer is to use 'carburetor cleaner' which is also flammable but a little less dangerous than using gasoline.After sitting a long time, our modern gasoline gets tired; never allow something to sit so long without adding some 'fuel stabilizer.'If possible with your car, I would drain (siphon) the tired gas out and replace it with a few gallons of fresh. Really tough starting problems can also be overcome with 'starting fluid' which is pure ether and very flammable.Any of these may require the removal of the engine air filter so the liquid gets into the intake manifold. Stale gasoline can also gum up the fuel injectors which may have to be removed for service if none of the fluids causes the engine to fire.
starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi
If you haven't done the following please run the tests to get the answer to your no start, the 1st and most common issue is fuel pressure loss due to a defective fuel pump, get a can of starter fluid and spray it into the intake, if you get the engine to run for a moment then the fuel pump has failed, it is located inside the gas tank, you will need to pull the gas tank to replace it, the next issue is a failed component of the electronic engine controls, to determine this you will need to read the trouble codes, the diagnostic connector is located below the dash just in front of the steering column, u can buy a code reader or have the codes read at a shop, this will lead u in the direction of the failed part, if the fuel pump is ok the most likely cause will be a failed crankshaft sensor..
The manual has a mis print, according to MINI the correct oil to use is ESSO CVT Z2L 799 fluid and there are no other manufacturers that use it so sorry but you will have to buy it from the main dealer.
