if engine will not crank, say that.
then say sounds. it makes if any.

Has to be a fuse gone or wires broken

You need to cycle the on/off toggle switch every time you use it....I know...stupid feature eh? Solution? Go into the options and change the "no enable" option to the opposite of the default setting, and you'll be great!

So do i by the sound of this question

check cables from battery to starter. if battery is good you should at least have power to headlights, other electrical.

It is possible that there is no power to the starter motor.
So check from the following:
1. There must be power to the starter solenoid , use a multimeter to test.
2. If there is no power to the solenoid when the key is turned then the key switch is faulty.
3. Check if this is a diesel vehicle that the HEATER TIMER works and then allows power to the starter as the starter works only after the timer allows the heater to work.
4. if the solenoid works then the power at the starter must be checked, if not the solenoid is faulty.
5. finally if there is power to the starter motor but does not turn , it can be a jammed pinion, a faulty brush or a commutator. Replace starter motor if a cleaning wont help.

Give me some more information about this problem. May be i can help.

The nuber one spark plug is on the passenger side of the backside of the engine. The back three cylinders are 1-2-3. The front three cylinders are 4-5-6.

Welcome to FixYa.com Look to where the drive belts are and you will see a cap black with power steering written on it, Regards, Lee

there is a rolling code that goes between the key and ews module. Aligning the ews and the key sometimes fixes the problem. (performed with bmw diagnostic equipment)Usually keys will fail over time due to the fact of how they are treated. If you have battery voltage at the largest post on the starter. I would check to see if while holding the key in the start position if there is voltage at the second largest post on the starter. this is the starter enable wire. if you see voltage on that wire then the ews system is working properly and the starter needs replacement. i would also try using a spare key, if you have one, to see if that fixes the problem
