I have a low mileage 2015 Commando Cafe Racer that was running fine and now just won't start. The starter works fine, and I replaced the battery. It fires with starting fluid sprayed in the cylinders. The fuel pump comes on and pushes fuel when I disconnect the fuel line. I checked the fuse that controls the ECU and the horn. The horn wasn't working either so I tried replacing the ECU/horn fuse a few times. Once or twice the horn would come back on but when I tried the starter the horn stopped working again so am guessing its a problem somewhere in that circuit. Am wondering if anyone has seen this one?

Welcome Don. If it fires with starting fluid, and the fuel pump is working, it sounds as though you have blocked or gummed up injectors? I’m not sure when they changed, but early bikes had a tubular steel fuel rail which would rust inside and cause blockage. If yours is not tubular it’s the later alloy version. I’d also use a multi meter on the horn wires, as it may be just a faulty horn. Also worth checking the connections on the battery, as there have been some poorly made crimps seen in the past, and the two fuse holders under the tank have been known not to grip the fuses properly, so just make sure they do.

My bike is a 2015 Cafe Racer - it has a steel tubular fuel rail.
I had a similar (not the same) fault that kept me puzzled for weeks. My bike had two cables crimped into a single non-insulated terminal end @ the positive terminal. It failed but maintained contact less periods of greater vibration, causing all sorts of problems. Not the same fault but worth checking.
The main fuse is a couple of inches down cable from the positive terminal. It needs to be cable tied into its housing, as it can become dislodged.
Does sound like clogged injectors though, or a faulty fuel pump.
