Default Cranks, Starts then Dies

Ok. Here is the cenario. Started bike heading to gas station. I was very low on fuel to the point that when going down hill bike sputtered. Made it to the station. Filled up started the bike, turned around heading out of parking lot. Just about to pull out bike dies.

So now I have siphoned the gas out. Put 2.5 gallons from another fuel station. Replaced the battery still same problem. You can hear the fuel pump running when you turn the key on. I placed my ear on the tank when bike tries to idle. You can hear the fuel pump but it surges. So is that my next issue or is there possibly something else?

What kind of bike do you have? If you suspect the fuel pump is not supplying fuel properly for your bike to run, you can confirm by using carb cleaner. It's much easier on a car but the principle is the same. Gain access to the air filter, pull filter out and spray a lil carb cleaner over the throttle bodies. Hit the starter button and if/when it fires up, spray the carb cleaner at throttle bodies in short quick bursts. If you can keep it idling this way but not with the fuel pump alone, then you confirmed the issue is lack of fuel.

He's riding a Highball according to his profile. It doesn't matter though. It sounds like the pump isn't pumping.
Try a fuel pressure test.

I've seen many a bad fuel pump get suspected then "eliminated" based on a pressure test. You can't completely diagnose a fuel pump on a pressure test alone. You can have high enough pressure but not enough volume. Pressure does not equal volume. Quicker just to go straight for the carb cleaner method.

I've heard that running a tank to empty sucks any dirt or debrie into the fuel system clogging it or forces fuel pumps to fail prematurely.

Could that be what happened here?

Unfortunately I have ran the bike out of gas on two previous occasions. Anyone know if you can order a new pump only or do I need to get the whole assembly from Victory which is $365.00. Also with the recall on 2013-2015 bikes what is the new part number on the fuel pump so I don't get a bad one?

I think your options on fuel pumps are to buy the entire assembly or send it to The Vic Shop (or similar) for rebuild.

go to auto parts store rent a fuel pump tester. You want 50 pounds of pressure. The vic shop might be able to rebuild it cheaper then a new one. By the way never run it low it burns up the fuel pump

Your getting some good advice.

Have you tried the factory procedure of priming the pump?
I'd start there. I'd try it a couple of times by the book.

It must be in both manuals for a reason. Perhaps what you are experiencing is the reason. Don't know till you try.
In the manual there is about 20 pages devoted to diagnosing what would seem to be a bad fuel pump. Would be worth your time to download a manual and pick your way through it eliminating the other possibilities one by one.


I would try the carb cleaner method of keeping it running as was recommended.
I always use gas in a good very small pump spray bottle.
I fill it completely with gas to keep the amount of air in the bottle to a minimum. ( don't tell anyone as it is probably unsafe) I do it outside with a fire extinguisher with the pin pulled out next to me.
I keep 2 fire extinguishers in the shop.
I do it away from the house, and the shop out in my gravel driveway. If I lived in the suburbs I would have an empty metal container with a lid handy to set the be spray bottle in should something go wrong and a lid to smother it or contain it. Metal trash can would be good.

I also cover up with a heavy jacket and gloves when I do it. However do unsafe things at your own risk. I'm in no way recommending you do anything you feel is out of your comfort zone.
Especially things that could lead to your own death should things go terribly wrong. I've never tried it with carb cleaner and that will be my first go to in the future. However I can't comment on how well that works as I have always used gas. But either should accomplish the same thing. One sounds a bunch safer than the other.

So if it continued to run with me spraying gas as needed or carb cleaner as needed. I would consider that proof that the pump or injectors might not be providing what is necessary for the bike to run. I would then glance at the injector plugs just to be sure everything looks plugged in. I'd also keep in mind that there is a fuel pressure pulse damper on the rail too.
No idea how to check that?

I might next throw in a new fuel pump relay or swap it with an identical relay (on a x bike the accessory relay) to see if the problem goes away and I would replace both the fuses associated with the circuit cause they are so cheap. (see manual) Don't forget to really inspect the plug that powers up the pump, under the tank. Maybe it never got plugged in all the way and has become damaged by arcing internally and is showing up just now. There is more in the manual to try.


If the relays etc did not fix it I would figure out how to rig up a pressure test without the required vic adapter. Harbor freight has a cheap auto fuel pressure gauge that you might be able to butcher to make it work on your bike? (Don't forget to ask around for 20% off coupons). If you buy a Harbor fright gauge you might want to hook it to your car first to be sure it works as advertised, before you start cutting it up if that becomes necessary.

Or just call a dealer and haul it in on a truck and have them do just the test. That can't be too expensive and it will tell you if the problem is really a lack of pressure or not.

If it turned out that it was a lack of pressure I would pull the pump and inspect the pump inlet filters to see if they are clogged. No gas in, no pressure out.



At the end of all that and the other tests in the manual, if it still wasn't running I might consider buying a new pump. But that would be down the road.
Right now you are assuming it is a fuel problem and it could be, but it could also be electrical, clogged filters or a connection or contact. Stuff happens.

Joe
he can here fuel pump run so I'm guessing its shit. He did say he ran it dry a few times so you can believe he burned it up
