09 XTX running on two cylinders. NEED HELP PLEASE!

[603NytroXTX]

Start simple, test for power at the injector clip AND ground when it's commanded by the ECU. I like to use a noid light if you can find one. You can also use a test light during the injector test.

Okay so I ran out and got some Noid lights and a test light. I could not get the noid lights to work on any of the injectors. Not sure if I had the wrong size or bad bulb but tried it both ways up and down with no avail. I used the test light and confirmed that the injector has power, same as the others. Problem with my test light is that the ground is a clamp and not a probe so I can't attach it to the other injector pin. I ran the diagnostic 5 clicks on the injectors with the test light on the left side pin (red/blue assuming it's ground) but it does not blink for any of the injectors. Just keep the light on the entire time it's touching the left pin regardless of what I do with the ground clamp attached to battery ground. I have a multimeter but it's an LCD readout so it's very slow and I can't tell my head from my #*$&@ using one of those outside of basic resistance and voltage readouts. I think I'm going to try attaching a pin the the test light ground so that I can insert into the other side of the injector. Any tips or instruction for what I need to be doing? I really thought the noid light would help but it's not working.

EDIT: Just ran the multimeter on all three injector plugs. Setup was grounded to battery.

Cylinder 3
12.7 volts left pin, .233 right pin
Cylinder 2
12.7 volts left pin, .180 right pin
Cylinder 1
12.7 volts left pin, .179 right pin

Okay so another update. I did a bunch more inconclusive testing with the Multimeter on the injector wiring harness. I ended up pulling the ECU and testing resistance on all the wires running from the ECU plug to the injector harness. It feels like the connection for the green/black wire (cylinder 2) is very finicky and any movement seems to cut the connection more than the other wires. When I have solid connection on both side I gently move the main harness in and out and it definitely feels like the green/black cuts in and out more than the others. I do have a spare wiring harness that I'm contemplating putting in at this point and then I can inspect the ones that's currently on my sled on my own timeline.

Okay final update so I can stop spamming this forum. IT'S FINALLY FIXED. The new wiring harness did the trick. Tried inspecting the harness that was on the sled but couldn't find any damage so I decided to yank it and try the new (used) harness. Injector 2 clicked during diagnostic test and I put the rest of it back together, fired it up and ran like it was supposed to. Also interesting that my thumb warmer adjustment switch actually works now. I thought the switch was bad but obviously my old harness had more demons than I thought. Thanks to all those that helped me with this. @grizztracks @olypopper @Srxspec
