Bike Won't Start, Fuel Injectors Not Firing

The Workshop
1

I am at a loss. I just got a 2013 675r, it was a barn find, it has 12,877 miles on it and it hasn’t been ran since 2017. It sounded like it wanted to start with some starting fluid in the throttle bodies. But further diagnosing revealed the primary fuel injectors are not firing. Here is everything I have checked so far:
-Battery Voltage while cranking is good ~12V
-The engine has good ground
-The ECU has good ground
-Clutch switch seems to be working, 0 Ohms when pulled in
-Kick stand switch seems to be working, 0 Ohms when in the up position
-Has spark on all three cylinders
-Fuel pump works + good pressure at the fuel rail
-Primary fuel Injector plugs all have continuous 12v
-Testing with a noid light shows none of the primary injector plugs are firing when cranking

I think that is everything so far. I am no master mechanic but I get by. PLEASE any input would be super helpful.

Thank you!

Hi and welcome, sounds like you are on the right track. Hopefully somebody will be along to offer some more advice.

From what you’ve said and what you’ve done, surely the only logical conclusion must be that the injectors aren’t actually opening and spraying. If it’s been stood for a long time with old fuel in it (and you’re in the UK) it could be that the petrol has evaporated and left the hard, brown gum that blocks carb. jets and, perhaps, in this case blocked the injector nozzle? Have you taken out and examined any of the injectors?

Wish you luck and hope you come back and let us know the outcomes.
