BMW Repair: misfire on 5th cylinder, volts and amps, coil pack

Question
i have a 1994 bmw 325i with a 2.5 six cylinder...

my question is my fifth cylinder is not fireing at all whe i switch the coil packs it does not make a difference i have replaced the fuel injector spark plug and coil pack, with no luck the car still runs on 5...  so i removed the coil pack from the problem cylinder and started the car and the spark plug was not fireing but i moved the coil pack to the 2nd cylinder and it fired fine ive checked all the coil packs they are fine....  any idea on why the 5th coil pack is not fireing?

Answer
Given your information, the other possibilities are wiring or computer problems.
All coils have 12 volts feed to them on the red/white wire.
Number 5 coil firing wire  should be brown/green.
Use a test light to check,not a voltmeter as that will give you a rough idea of volts and amps.
