No spark at #4 cylinder

My 1993 325i is having trouble
Well hello everyone , my problem is i changed the plugs, i changed the coil packs due to a misfire in the engine.I ve recently put on new mass air flow and cleaned the I-C-V. The misfire is still there. I have to believe at this point the only thing left would be wiring from the #4 cylinder. I got a feeling this may lead me to the ecm. please help if you have any feedback. Cylinder #4 still has no spark

Is there a crank position sensor on your engine? Could that be the issue? Have you confirmed visually that have no spark, or is just that cylinder for isn't firing? My point is could it be a dead injector?

You need to remove number four plug and connect to its coil, earth it to engine to eliminate plug/coil as fault...
If no spark = Electrical
Good spark = Fuel Injector or valve

If you haqve a spare plug laying around (one of the old ones that you recently changed out is probably good enough) use one of them instead of removing the new plug from the head. It may avoid a small fire from fuel being blown out through the plug mounting hole and igniting on the spark. Hopefully its just an injector issue.
If you have a mechanics stethoscope listen to each injector to see if you can hear it firing, otherwise try screwdriver by putting the pointy tip against the body of the injector and the blunt handle in your ear.
Good luck
