Need Help Bike Wont Start (occasionally) Fuel Pump Not Priming
Alright latest issue, If you dont feel like reading my long story heres the short version
Bike started off by having trouble starting sometimes, would turn over but not fire, usually id give it some time and try again and it would fire up.. (Happened the day i bought it about last weekend, and a few other times) Now yesterday it stalled on me while I was riding and wouldn't start back up again turned over but wouldn't fire... Eventually I realized my fuel pump wasn't priming, so im guessing it wasn't running while I was riding that's why it stalled also.. Since its stalled now my blinkers aren't working either.. any ideas, Skip the story if you want and my questions and ideas are below it...
If you think you can help maybe read the story too so you get a better idea..
So the night i bought my bike a 03 Honda CBR 954 rr, I stopped at the gas station to fill up, and it wouldn't start (turning over but not firing) I tryed and checked everything I could think of, Kill Switch, In gear, in neutral, kickstand, ect... eventually after a little while of sitting there looking like an idiot i tried it one more time and it eventually fired up. Like it was nothing rode home and it was fine.. Then later that night it happened again same thing it would turn over but wouldn't fire up, let it sit for a little while and bam it fired up... I cant remember if it happened anymore after that, I think i charged the battery, and it stopped (or so i thought)
So last night i was riding home, at a stop light my horn starts faintly going off by itself (I thought i heard the bike doing this before but this is the first time I noticed it for-sure) then i make it to the last turn to my street a red light, im sitting there sweating my but off cause its so hot and humid and i just got done running around.. I was first at the light with a line of people behind me, so when the light turns green i start to release the clutch and give it some gas to take off but to my surprise the bike stalled, i thought it was because i had let the clutch out to fast (which i hardly ever do) but then i go to start it back up quick because i got a bunch of dummys behind me in a hurry to get home yelling crap.. and the thing wont fire just turns over but not starting (it started a couple time but would just stall real quick) So I walk my bike out of the lane so they can get around me (middle of a 6 lane road with a divider in the middle, and i was right in front of the divider, but anyway) i let it sit there for a minute tried it a few times still nothing so i say screw it and walk it over to an empty parking lot across the street, tried it a couple more times still nothing.. let it sit for a few minutes still nothing.... so i decided since i was close to home ill just walk it home... (tried it a few times on the way down the road still nothing) would just turn over but not fire up... By the time i got it home the battery was dead, (Probably from trying to start it so many times.) so i hooked it up to the charger. Went inside, came back a little while after tried it again and it starts right up..... So i turned it off and let it finish charging thinking it was just a dead battery or something.. (Obviously not the case)
So today i pull it off the charger me and my brother were going to go somewhere started up fine no problems, except now i notice my blinkers are no longer working (I have integrated taillights, and flush mounts up front) the blinker light on the dash comes on but it comes in faint not the bright orange, its not blinking on the dash either, just stays there the dim orange... When we stopped for gas i shut it off or it stalled cant remember, i think i shut it off then i started it and went to take off and it stalled (pretty sure thats how it happened) so me being the smart person i am try jumping it with jumper cables cause charging it seemed to fix it last night.. but nothing just doing the same thing turning over but not firing.. I put gas in because it was low after that figuring might as well rule out that im out of gas... go to start it and same thing... but after a couple trys it started up... Then we continue on our way to where we were headed get about half way there and as im coming to a stop sign it stalls....! So we pull over look at each other like were idiots thinking to myself i should have just turned around and went home.. but this time I figured out the problem!!!! The damn fuel pump wasnt priming there fore the engine isnt getting any fuel.... So to make this long drawn out story short I turned around after that and headed home! Having to stop and wait for the stupid pump to start working 2 more times....
So my question is.. WHAT IS CAUSING THIS???
Im not very mechanical I mean I can do something if im given good instructions but I dont know how to figure out whats causing this..
My ideas, It must be something electrical, because that would explain why the blinkers arent working and the horn randomly went off (which hasnt happened since)
Or maybe its just the fuel pump? but then why arent the blinkers working all the sudden?
Could my power commander be causing some sort of problem?
The guy i bought it from wired something wrong and its causing things to short out? (Has HID head lights, Integrated taillights, Flush mount blinkers, Power Commander, and i think theres a couple other things im forgetting to name but yeah you get the idea..) If thats the case where would i even begin to fix that mistake and or how would i trace where the mistake is?
I thought it might be the batterys bad but im pretty sure thats not the problem now?
Or maybe its something with the ignition?
I've checked all the fuses that I could see at least (under the seat) They all looked fine.
I dont really know how to check weather or not things are getting power to them so...
Please help me figure this out because this really sucks...
