Friend bought a 796 that won't start. It's having a weird injector issue and hasn't ran in a long time it seems. The bike only shows 700 miles on the dash.
Things i have checked. Battery fully charged outside of bike(tried 2 batteries.
Bike cranks strong with good compression H: 166PSI V: 168PSI cold.
both spark plugs are firing and dry(leads me to fueling issue)
No codes showing in jpdiag software.
Fuel pump primes when keyed on. I pulled the pump assembly anyway to make sure the hoses aren't split or disconnected.
Fuel definitely gets to the injectors. I accidentally keyed on with the injectors removed and fuel poured out of the lines. Even with low fuel pressure I would think the injectors would spray weakly.
Here's the weird part. When i key off and on then hit the starter, the horizontal injector fires once and that's it. I can't really see the vertical injector due to the angle. It will do this every couple times keying off and on. I pulled the injectors and applied 9v to the terminals and both injectors clicked. I used a mechanics stethescope to confirm both injectors are clicking while cranking the bike.
I poured a small amount of fuel into each intake and the bike ran for a bit so its definitely something with the injectors.
I got a used set of injectors that also click while cranking but won't spray gas at all.
I'm thinking clogged injectors? its weird that they click while cranking but wont spray fuel. Also, the horizontal injector sprays once when first cranked which is strange.
Any suggestions?
