Ran out of gas on my 2001 f4i. I filled it up with gas, then tried to start it. cycled the pump afew times...nothing..cranked the gas a few times.... nothing.... hooked up a battery charger.....nothing... it cranks, but doesnt turn over. Is there a dafety switch on the comp? Did I hurt the pump? Foul the plugs? I know somebody else had to be as dumb as me and run out of gas. If anyone knows what it could be .. I would appreciate any help. Thanks

well maybe this will help even thought I have an F4... My bike hasn't started since my accident in August, and I had everything apart to check the carbs out and make sure they weren't gummed up and put new gas in the tank and changed the fuel filter.. So I put everything back together and killed my battery trying to start it. I'm like what da hell??? So I took the fuel pump off and that was working.. Pulled the plugs out and they were fine and there was even spark.. Now I noticed that the fuel pump only comes on for 1/2 a second. I noticed air in the fuel filter and figured the pump wasn't running long enough to get fuel to the carbs.. I put a cap full of gas in each carb and waited a minute and then she turned over... Go figure..maybe it's the same for fuel injection.. Hope this helps..

a thought

Do you have the kill switch ON? Just something to look at. My Honda will turn over til the battery dies with the switch OFF, but it won't start.:)

Ok, the fuel pump is lubricated by gas in an F4i, running it dry will ruin it quickly. I would try to see if the fuel pump itself if working ( ie. pumping fuel ) and if not swap it and see if that does the trick.

Ummmm yeah.. I know it's fuel injected, but if the fuel system isn't primed your bike isn't going to run.. The fuel pump only runs 1/2 a second until the bike starts.. if it doesn't start the fuel system doesn't get primed.. Putting alittle gas in each runner will give it enough so your bike runs long enough to get fuel into it... Look to see if there is an air bubble in the fuel filter.. If there is then that may be the problem.. If not.. then take the fuel line off where it goes into the fuel rail and see if it's even pumping when you turn the key on.. If it does then the pump is ok.. Take a plug out and crank the engine to see if there is a spark.. Check all the fuses.. That's about all I can tell you other than seeing if it's still under warranty and taking it to the dealer..

The last suggestion sounds good, but I really don't think running out of gas one time is going to ruin a fuel pump. And to buy a 200.00 fuel pump to find out that isn't it and not being able to return it because you used it, to me isn't worth the risk...

What you are probably experiencing is called vapor lock:( It's not a big deal, just open the gas lid, turn the key on two or three times, and turn it over with the lid open. Let it run for a few then shut er off and close the lid. Another quick fix is clamping a wooden close pin on the fuel line:confused: I don't know why it works, but it dose. I never had this problem on my F4i, but my cuzin did on his F4, he used the cap open technique.:D Good luck.

Yeah I thought that too and left my cap up and that didn't work for me... Hence I poured alittle gas down each carb and a minute later she started...

Well it dose work off of gravity, but vaccume will have a lot to do with it also. The bike needs the vaccume that the running engine produces in order to pressurize the fuel lines. But, I don't know if pouring fuel down the Throttle body of a Fulie bike is too good of an idea:confused: . This could cause seriouse back fires.:eek: If opening the cap dose'nt work you amy want to try using compressed air to clear out the vent hoses. Pouring feul down an open T.B. should be the last resourt.:cool:

Well actually I probably wouldn't use a full cap.. Maybe take just soda cap full for all 4 runners... I didn't have any problem with back firing of any sorts.. I guess it was enough gas to get the engine running long enough to get gas through the lines. Or how about spraying ether instead of pouring gas:confused:

I would refrain from pouring fuel down your throttle bodies. Instead, go down to the auto parts store and get some starting fluid. Starting Fluid contains a top cylinder lubricant, thereby lessening the damage of starting.

If nothing else, try push starting it in second gear. Even if it doesn't start, you will crank the engine over faster then the starter. This will develop a little bit of engine vacuum. I think the fuel pump is switched by engine vacuum on that bike. Once there is some vacuum, it will switch on. I don't know if this works, (just a thought) but you could try sucking on the vacuum line that goes to the tank while cranking. Who knows, it might work.

the Starting fluid worked!!! the bike was not getting enough gas from the fuel pump. It energized but wasnt pushing the air through. once I got it started twice with the starting fluid. it stayed on and has worked fine after all day of riding. Thanks guys. when that light comes on in the F4i My advice is to get your ass to the gas station. and dont forget your wallet about 40 miles from your house too would help

There is a section in your owners manual that tells you what to do when you crash or run out of gas. follow the instructions in there and you will be riding again soon;)

Yeah, let's all suck on on the lines comming out of the gas tank... it must be safe to inhale gasoline, after all the bike loves to.

:rolleyes:

(oh, and for those of you who didn't figure out that is sarcasm. If you die from sucking on lines going to the gas tank, it's your own dumb ass's fault.) :p

No twisties in VA Beach, just cops. You have to drive to NC to ride the winders (30 min). A lot of posers out here, but there are some real good tricksters.
