Hi everyone, I have a 2004 VFR800 ABS with very low kilometers in great condition. It has not been ridden for a few years, and has a full tank of fuel with fuel stabilizer. It has a Power Commander and O2 eliminators, but everything else is 100% stock, no PAIR valve mods etc. It has not had the wiring harness recall, or any other recalls etc. I'm going to install a brand new battery in the next few days. Last year when I tried to start it, the motor would turn over, but would not run unless I put a few drops of fuel into the intake, and then only for a short bit. This year who knows, but I’ll report back and thanks so much in advance for any advice you have!

Does the fuel pump prime when you turn the key to start?

Ignition spark at the plugs?

Fuel pressure regulator?

Blocked injectors?

Those are the things I would check

Sorry, grasping at straws here. I'm sure others with more experience will chip in.
