HELP...one of my cylinders is not running

[drift_ricer]

hi guys. here the problem. right now my car running 3 cylinders. one of my cylinder is not firing. I don't know why, so I tested. I tried to change ignitor chip from a friend, and still not work. then I tested sparkplug, and coilpack, and still not work. I also tried change ecu, and still not work. I am guessing right now is the wiring harness problem...U guys have any idea? thanks

check fuel, spark and compression and go from there

Once upon a time my #2 cylinder quit firing. My injector quit spraying. If compression is good check the injector plug and the injector itself. Hope you fix it.

I checked already, compression is good..even though no firing, but there's fuel around the sparkplug..help please, this problem bugging me for 3 week already...
