RC won't start

I have an RC51 SP2 that I bought used and had to repair the tank. The bike sat for the winter and some of the summer (it ran fine before that). I drained the fuel for storage and the like.

Now I got the tank done and installed it on the bike. Filled it up with fuel and nothing. It will roll over, but won't fire .

I'm not smelling any gas. Do you think the injectors may be clogged or do I have to just keep up with trying to start it? In other words, "is it normal to take some time to get the bike to start after some storage time?"

Any info would be great. I'm getting no fault codes from the FI.

Is the fuel pump priming when turning the key on?

Yes it primes. That's why I'm so confused. Do you think maybe plugged injectors? I'm going to check out the spark plugs soon to see if they have gas on them, but I don't think that they throttle bodies are pushing out any gas because I smell nothing when I try (normally you can smell gas if the bike is flooding or not firing).

Make sure all the connectors are intact. Maybe something got bumped!

Probably injectors clogged or possibly not getting a spark so check the plugs and clean em real good or go ahead and get new ones. Just an FYI the bike is fuel injected so it won't flood, only carb motors do that.

Fuel injected cars/bikes can still flood if there's no spark. It keeps spraying fuel until it starts.

Check the spark bro. Take off a spark plug, connect it to one of the ignition wires and hold it towards a ground i.e. the frame, motor ect. and crank it. If a spark jumps the gap, spark plug and coil is good but remember that you need to do both.
