2001 yamaha v sta 650 ran out of gas. And wont start back


I know that quite a few of the V-Star's have an issue with fuel that has Ethanol additives. What happens when the bike sits, even for as little as two weeks, the fuel start to "gunk" up in the carbs. If you had any trash in your tank, you could of clogged the fuel filter.

Something you can try, without a lot of diagnostic testing, is to add SeaFoam to the gas tank. Use the recommend amount of SeaFoam for the amount of gas it takes to fill it up (I believe it's about 4 gallons or a bit more). Also add 1/4 ounce of carb cleaner (B-12 works great).

Before doing any of the above, I recommend that you check the fuel filter, fuel lines, fuel on/off valve and remove the carb bowls to check for any trash or gunk.

Now you can try starting it again, but put a trickle charger on the battery to help keep the battery up while starting. Start out with the Choke at full and try to start it for a few minutes. If it starts, let it idle for 10 - 15 minutes to allow the additives time to run through and clean the fuel system. Make sure not to run the battery completely down.

If it still won't start, pull a fuel line off a carb and try to start it. If you are getting fuel through the line, it's, more than likely, not the fuel system and could be electrical. Although I've never heard of an electrical issue when running any bike out of gas.

One other thing... try starting it with the fuel on/off valve in the RES (Reserve) position.

This may sound silly, but check the Run Switch to make sure that it didn't get knocked out of place - even slightly.

I've been racking my brain since your question appeared over 3 hours ago. I hope the information that I have given you, will give you enough of a starting point that you can figure out the problem.

If you find this information useful, please vote. Thank you.



NOTE: I have done this, but I do NOT recommend it. Do this at your own risk. Get a spray can of starting fluid, find your air cleaner and give it a quick shot. Back away from your bike and try starting it. It will either start, or pop and backfire. If it didn't start, try one more quick shot, again backing away from the bike while trying to start it. Once the bike starts, and you have added the above chemicals, you shouldn't have any trouble starting your bike again. One more thing, if you use low octane fuel it will have Ethanol in it... use the SeaFoam every other full tank. Only use the B-12 once. If your bike is going to sit for an extended period of time, get a bottle of Sta-bil and add the recommended amount to the gas tank. Run it for a bit, shut it off, and shut off the fuel valve.

Heavy gas smell but no apparent leeks, when starting the bike does not turn over the first time and the clock zero's out then starts on the second push of the button.

Fuel tank on your bike is vented to the atmosphere, and especially when the tank is full it is commom to smell gas.

If the clock zeroes on starting, your battery is weak. Check the battery terminal connections by removing the rider seat and looking in at the battery. Try to wiggle the wires connected to the battery and make sure the connections are tight.

Next, put a small charger on the battery and let it charge up for several hours.

If clock still resets on starting, you will need to replace the battery on your bike.

Good Luck

Bike did not run for a few months , and now when I am starting engine runs and then stops after a minute or two.any help? bad fuel?

This sounds like a typical case of gas going bad and possible rust in your gas tank. Best to drain ALL gas from your tank - if you can easily remove it - take off the petcock and rinse the tank with fresh gas - look for any flakes of rust in the gas you drain out. Once you have the tank fully flushed - clean or replace your fuel filter and I would suspect that it will run just fine.
If you are not going to ride for an extended time frame - add Fuel Stabilizer" to the tank before putting it up. This is available at your local auto parts store. You will thank yourself for taking this precaution.

2004 chevy 2500 wont take gas into gas tank

I am having the same problem. When turning the pump on full speed it will pump for a few seconds before kicking the pump off like the tank is full even though there is no gas in the tank. I can pump gas if I barely start the pump and hold it by hand but very very slowly so it takes about 20 minutes to fill up. Its not the gas station or the way I am holding the nozzle as I have stopped 20 different places and tried every way imaginable to hold the nozzle. I have changed the filler neck, charcoal canister, and the sensor/filter that is on the side of it that I believe opens to allow fuel vapor to escape and let pressure off the tank when the truck is not running... still no luck. When I had the fuel next off there is a check valve that is made into the top next part of the tank that is spring loaded. I figured this was to keep gas from running back out in the event of a rollover and possibly keep someone from putting a hose down the next and stealing gas. At this point that is the only thing that could possibly be causing the pump to contiune to kick off every few seconds when filling up the tank. Next is to change the tank I suppose unless someone has already ran into this issue and can tell me what I need to do to fix the problem.
