Fuel pump not working

Went to turn on my bike, didn't hear the fuel pump engage. I just put a brand new one in a month ago. Turns over but won't start. Keep in mind I'm not exactly a motorcycle expert. What's wrong with it?

Check the cables inside the starter and kill switch. Maybe your relay got stock?

Next time your fuel pump doesn't prime try flicking the kill switch fast a few times (with ignition off) and see if that does it...then it's a dirty or loose connection.

If that doesn't do it, pop the seat off and tap the relay. The manual says which is for the fuel, tap it with the back of screwdriver and see if it might be stuck.

That's what I'd do firs.t

That damn killswitch should be removed! I noticed it first on my 2004, then while rebuilding my 2002 I noticed the same problem. Since I had the 02 apart, I went ahead and cleaned it up. Easiest way to tell if its the problem is to set it to run, then tap on it. I was able to get the fuel pump to recycle doing that.

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

The kill switch is a known Honda weak point. People need to stop using it in general and use it only in emergencies.

So I got it running and ride around, but she'll turn off randomly. Once at a stoplight and the other while riding. Where is the kill switch located

Real question though is there a throttle out there which does not have a kill switch? Something sleek simple and low profile?

Lol, don't worry about it. It's taken me way too long to learn that it's better to ask the question if there's any doubt or possibility of misunderstanding.

Every now and then I can get it to start working. Do I need to go ahead and buy a new kill switch? This shit is driving me crazy.

If it starts working when you are jacking with the kill switch just take the switch apart and clean up the contacts....then stop using that switch.

You sure you put it all back together correctly? Check for any loose wires if you can.

I had it back together for over a month and everything worked great. Is there something in the kickstand that would keep it from working?

I haven't been following the thread but, if it does turn out to be the pump, I have have one I'll make you a great deal on. The original owner changed it for a new one because the low-fuel light came on early, don't they all, but this one does the same thing.

He had it swapped when the bike had less than 1,000 miles so this one is like-new.

Fully charged the battery, fuel pump still won't turn on. Cleaned the connections on the killswitch. Still nothing.

If it was way less than $150 and there were more details available I'd certainly be looking at purchasing one. If it doesn't fit the 919 it'll fit the cbr250. Looking at the pictures they have different cam sizes available.

Anyone want to contribute to the fund to see if it'll work with the 919?
