Okay with a cooler head, and warmer weather I went and tried to start it again. No dice. Turns over great, all electronics seem to be working as expected. I tested the following things, and I'm still at a loss of what to do next.
1. Overall voltage. I've got it connected via jumpers to my car, so we're at about 14v.
2. Fuel injector coil. All coils are sitting at 16 ohm as specified.
3. Disconnected the TPS, some corrosion on the connector, but even with disconnected it doesn't want to start.
4. Disconnected one fuel injector plug, turned the bike over, and couldn't see an voltage getting to the injector.
5. Tested all the fuses, continuity across them all.
Seems very much like a fuel issue, and I am unsure what would allow instruments, crank, and spark, but no fuel. As I mentioned if I remove the hose from the rail, it'll push a stream of gas through, and I can hear the fuel pump recharge the system when done cranking.
Sad day for my K!! Want it back on the road!!
