2003 cooper s no spark on cylinder 2 HELP

I recently had a p0304 (engine misfire detected) code come up on my 2003 mini cooper s and have read almost every thread I could find. I did notice the same corrosion problems on the poles and replaced the coil, changed the plugs and wires. Now I have p0302 code come up and I have no spark on cylinder 2. I used a timing light on each plug wire and cranked the engine and 1,3,4 all have spark but 2 does not. I place the old coil back on and same p0302 code. I have reset the ecu and still no luck. Is it possible the "faulty coil" could damage the ecu. I am thinking it is the ecu but any suggestions???? HELP

Thanks in advance

Your new coils may be OK but have you checked the new plug lead ? it could be a faulty plug lead.

I swapped different plug wires and still do not get any spark after the coil. By using a timing light on the spark plug wire you can see if you are getting a spark when you try to crank the engine. Changing plug wires still had no effect. 1,3,4 all have spark just not number 2.

Hi ya

I take it you have tried different set of spark plugs or swap your plugs around.
If the spark plug is not discharging the charge from the coil pack ie failed or fouled pug you will not get and indication on your timing light.

Hope this helps

Thanks for the tip but, you can check the spark on the wire without it being connected to a spark plug with a timing light. Just disconnect the wire from the plug and connect the light to the wire. I tested this on each cylinder and it works on all without a plug. any other ideas?

Marque, I want to thank you for your post. I was really confused why the timing light worked on 3 of 4 cylinders not attached to plugs. I moved the plugs from 1 to 2 and the problem did move!!!!!! The plug were changed recently that is why I ruled out the plugs. (stupid on my part, I know better) New plugs and reset the computer and she is running great. Thanks for the help.
