Vstar fuel pump clicking

when I start up.     I turn key on and turn off kill switch ,   The usual fuel pump noise comes out for a few seconds then yellow light goes out and green neutral light is on.  I pull choke out and hit starter button.  Starts then dies ....  every time I try starting again the clicking fuel pump makes its noise again.   I never paid attention but I thought it only primed once.  I was thinking my battery needs replacing but thought I’d do some research.  Any ideas or experience ie welome and appreciated...

When did first start doing this?
Was it all all once or gradually got worse?
Had it sat for awhile?
Bad fuel, possibly.
What do the plugs look like?
When the engine stops, the pump looses pressure.

You may want to check the fuel presure. While checking the fuel resure make sure the relay stays on long enought. It should run for 3-5sec to build presure. Then replace the fuel filter. What edwin's say's

Well fuel pressure could be it …. especially when I found there was no fuel … added fuel now it seems the carbs need cleaning... will perform a simple cleaning of the jets then test again. I'll post the outcome, thanks for the troubleshooting listed above...

Run some Sea Foam throught it a couple tanks. That will help clean up the tank and the fuel lines. Don't for get the filter.

thanks scruffy and Edwin...will post outcome

cleaned jets on bike procedure... worked like a champ. now I can actually start it in colder weather. need to buy an oem filter though. how much seafoam do you put in your tank?

That is great you got it figured out. The Sea Foam is about 1 oz per gal. If You get a little more it won't hurt any. Try this site for parts www.cheacycleparts.com I have used these guys for several years. The prices are good but some times you can get the parts you need cheaper at the Yamaha dealer. Just have to check on prices.

thanks , the way it revs now I am anxious to see the top speed now... I will try the parts place listed too, thanks scruffy

YOUR welcome and have a great Thanksgiving..
