Exclamation 2003 CBR600f4i - Not starting

Whats happenin CBR fam...So I'm working on my recently acquired bike, however I've encountered some issues along the way.

Novice mechanic --- Manly 4 wheeled cages, also known as cars and trucks

2003 CBR600f4i about 18,000 miles on it
-Sat for 1.5 years in garage
-Only need a regulator rectifier per previous owner, who happens to be my lil bro.
-I also have the Haynes manual in color for this bike

So work that I've done...

-Replaced Regulator Rectifier
-Replaced Spark Plugs (NGK iridium of course)
-Replaced Gas Full Tank (87 to start)
-Oil Change (Full Synthetic)
-Coolant Flush (Engine Added)
-New Battery
-Bike is currently in my garage on bike stands

Of course after doing all of this, the bike won't start
-Fuel Pump does not prime
-Tried jumping fuel pump relay, nothing
-Did feel fuel pump relay "click", but not priming
-No rust in gas tank either
-No gas going to fuel rail
-Fuel hose looks/feels dry
-Took hose off of fuel rail, no leakage from tank?
-Checked all fuses...none blown
-Wiring Harness looks good
-Instrument Cluster lights up normally
-Headlights work, well the high beam does currently
-Thinking the normal headlight is out?
-Kill switch relay works, hear click
-Bike does crank/turnover
-Bike does not start

I think that's it...any assistance the CBR fam can provide is greatly appreciated.

Dee

Fix the low beam headlight. IIRC, the BAS runs through it.

Update...so in looking at the headlight wires they looked ok, once I actually felt it, I knew something was wrong. The wire was way too stiff, and the connector on the ends starting breaking off while try to unplug the connectors. I will update with more info once completed.

UPDATE...so I replaced the headlight wires...had one of my boys, who actually works on and races bikes, take a look at it. He said I need a fuel pump. Ok I called Honda and they said 480 for the fuel pump...$480, it's for a bike not a car...Any other suggestions on where to get a reasonably priced fuel pump in working order for a 2003 honda cbr600f4i???

BTW, apparently the fuel pump went bad because of the old gas sitting in there for about 2 years. I did try to jump/bypass the fuel pump to see if it would prime, no dice.

How does that change anything? Car or bike its still an electric pump that moves fuel at a pre-determined rate and pressure. Besides, bikes are low volume, so price per part is higher.
Either find a used one or buy oem. Don't get a chinese ebay one if they are even available.
