Ill check that in the am. I did check to make sure it was connected all the way and it was. I unpluged with it running amd no different...

I had the same code on my '98 XJ a few months ago. The some of the wire ties that hold
the wire harness that runs across the firewall had rotted away and the wire harness had
slumped down just enough so that it had been rubbing into the rear-facing end of the fuel
injector rail tube. It had worn through the wire insulation and caused an electrical short.

Swap the injector from cylinder 2 to a different cylinder. If the misfire follows with the swap, you have your smoking gun evidence of a bad injector.

Even easier is to swap the #1 & #2 connector plugs. If the #2 injector fires with the #1 plug, then the injector is good. If the #1 injector now fails with the #2 connector, the problem is in your wiring harness or pcm. If there is no change after switching connectors then it is a bad injector.

Ok so something weird about all this... it says its number 2 injec but its really number 1 not working... also I checked voltage on injec plug and found number 1 to be getting 14-15 volts and 2-3 getting about 2-4 volts... any issue here? Lol what should be my next step? I swapped the asd relay just because also...
