I just bought a 2000 V Star 650. It needs a lot of work that I am getting through, I just replaced the pick up coils, spark plugs and rebuilt the carbs, I was able to get her to fire this weekend by spraying starter fluid into the intake but I wasn't able to keep it running. I think it might be the fuel pump but I wasn't sure so if any of you know or have any tips, that would be appreciated. Thanks.

I renewed the fuel pump on my 2007 V Star after checking every thing else ,even though the fuel pump was clicking away as it should. To check I by passed the fuel pump and put a fuel pipe directly to the carbs and poured fuel into the pipe with a funnel and the bike ran normally , good luck.

If the bike was left with fuel in it, the fuel pump could be stuck. I put a blast of compressed air into the fuel line towards the fuel pump and it made a weird pop and then the fuel pump worked again. This corn fuel is sticky.

suggest reading the attached post.

drain your tank
inspect fuel tank internal for rust
fill with fresh gas
check for fuel flow at outlet of petcock valve in run /reserve positions
consider replacing your fuel filter
disconnect fuel line to carbs and check for fuel flow by catching in bottle by turning key on to ensure pump is working
check the other guidance in the post below

let us know how you make out. If you get it running, sync the carbs. Look in the main VStar thread for a link to shop manuals.

Check your shut off valve for flow, pull the rubber hose off on the outlet and see if any runs out, they get plugged up from bad petrol,... work down from there.

Thanks for the help everyone! I did the fuel pump yesterday but my battery died so I threw it on the charger and will try it when I get home from work. I really appreciate it and will let everyone know what happens and likely come back for more help, this is my first v star so I'm sure I'll need it.

Alright, she still wouldn't kick over last night, even with some starting fluid. I've got fuel flow coming from the tank and it seems to flow through the fuel filter, I disconnected the filter last night and emptied some fuel with it passing through the filter, do you think that means I should still replace it?

It cranks but will not fire up right? have you tried hitting the carb bowls with a wrench? You may have stuck floats. If not starting with starter fluid is maybe a spark problem. check for spark.fuel pump sounds like it is working pump will only run for 10 secs. when key is turn on and only if it need to. so it never runs all the time.

Also, check the kill switch!

I haven't hit the float bowls with a wrench, but I'll try that tonight, correct it cranks but won't fire up. I'm reasonably certain it's not a spark issue, I just did the spark plugs and coils last weekend and made sure they were gapped properly. And the pump does only run for about 10 secs before it kicks off, then when I try to start it, it doesn't start and then I when I come off the button the fuel pump comes back on for a couple seconds before it kicks off again.

Go to Harbor freight, you can buy a very cheap spark checker, if it won't fire using starting fluid it is not the fuel system.
If the starter turns, it's not the kill switch.
You only need 3 things for it to fire, fuel/air mix, spark and compression.
You can tell if you have some compression by removing plugs ,put a finger on the hole and turn it over, you will feel it push your finger. You know spraying starter fluid it has fuel.Last is spark, I use a spark checker just because I always get zapped using any other method and I just don't like it.

Hello everyone, it's been a long time. I got the sparking issue sorted, fuel pump done, working on rebuilding the carbs once more but far more in depth. I think I cleaned the major components last time but didn't do a detailed enough clean. So in that endeavor I discovered a couple things, first of all one of the screws that is on the jet side, the head broke off. As far as I can tell the screw is primarily used to hold the float pin in place, so I was wondering if any of you knew what that screw was called and if any of you had a good link to a parts manufacturer that would have that kind of thing. I have pictures of the location if you need that. But also I had to use some forceful means to get the carbs separated from the mounting brackets, so if y'all know where to get hardware like that, that would be lovely. Thanks everyone.

V Star 650 Carburetor issue?

Hello, everyone. I hope everyone is having a good day/night. I just recently bought a V star 650 Classic (01) for $1,500. The person who sold it to me said he was selling it for so cheap because he said he messed up the carburetor trying to do a DIY job. Something to do with either the needle...
