I have suspected a bad injector on the number 5 cylinder but now I think maybe it may have low compression on that cylinder. Listen to how the engine turns over in this video. The engine was running rough below 1500rpm but now it will not start at all after breaking open the fuel system to inspect the 5th injector. I have been struggling with INPA and have yet to get it working correctly so I have no idea exactly what is going on.
