Bad injector or bad injector plug

I've been chasing the issue of code 27 I tried swapping plugs on the injectors seems like nothing changes I have approximately 14 volts on the one plug I can get my fat meter probes into. I'm leaning towards bad injector.

Any help would much appreciated.

Well I swapped injectors no change looked over my injection harness and nothing is standing out. I'm picking up my Oldmans compression tester tomorrow maybe I lost a valve. My spark plugs look good wires are like a year old tonight I'll fire it up and look for sparks. Any other advise would be great.

I fought a miss for quite some time. Every time I tried to isolate, it went away. I finally just replaced all six injector connectors (Rock Auto, $3 each, with 12" wire leads), and soldered the new leads into the harness.

Problem solved.

Damn Ok I'll order some connectors I'm running for 24# injectors and they work I stuck them over 6 glass jars they all squirted but I'll keep them in mind too.

Thanx

Problem not solved any other advice anyone. I'm feeling like buying a new jeep and swapping stuff over but I should be able to fix it but I have no correct direction.
Like 400+ for a reman computer are they really worth it?
