Do you have any Fault Indication on the MIL light?
Can you hear the relay click when you first turn ignition on?
Note that it should turn on for a few seconds then turn off again. Power will not be permanently applied to the pump so any troubleshooting you do will require to be done in those first few seconds after you turn on.
i.e. connect test leads to the pump connector and look for power immediately after turning on ignition - if you have power, then pump is bad.

i had this problem before,i suggest first replacing starter valve w/ a chinese equivelent part(cheaper than honda but the same),can also replace w/ manual enrichener plunger, but it is inconveinent to access, or what i did was seal off plunger hole and squirted gas through fuel line and a primer bulb, teeing off from main fuel line run spigot fitting into plunger bore and jb weld to seal.now mount primer bulb in convienent location.definitely an unauthorized repair and a little tedious to fabricate ,but works like a charm, as those starter valves are notorious for not working correctly.

Are you adding oil to the gas? (32/1 = 4 ounces per gallon)
Do you still have spark? Install a new stock spark plug.
Clean the carb, but follow these steps >
Remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Let the bike warm up then set the idle speed. This process should get you back on the road.

check your key it has a chip in side it and it may be faulty try your spear and i know it sounds silly but just make sure your kill switch is set to run check the hiss fuse under the seat also swap your fuel pump relay with the fan one the fuel pump relay has brown wires going to it and the fan has black and blue if you have an alarm on it it will be worth checking that make sure that the fuel pump is pluged in under the tank take a look at the hiss light does it go out wen the bike is switched on if it stays on you have a HISS problem any problems let me know and i will do my best to help

check for spark, make sure the test plug is grounded to the engine or it can damage electrics
