Ive been dealing with a P0200 injector open circuit code for a few days now and im completely stumped. Today I checked the ohms on the injectors and they were fine, I checked the voltage of the voltage feed wires and they all read 12v+.
I ended up finding a signal wire that was broken off from the injector connector, so I soldered it back on and checked the rest for safe measure and they all checked out fine. I started the car and let it run for about 10 minutes and it ran perfectly and the codes disappeared as well, so i went ahead and loomed the harness back up and started the car again.... bam the code is back and it has a very rough idle. I removed the harness again to see if I accidentally pinched anything and I see nothing wrong with it, anyone have a clue of what could be going wrong here?

 

Update* I fixed the issue turned out to be a cut in two wires and they were touching each other so i heat shrinked each one and it works perfectly now
