had been riding with my headlights off for about 3 weeks, put them back on a few days ago, rode thanksgiving day for a few hours and didn't like how i felt, so i decided to take them back off, now my bike won't start, but the fuel pump is still coming on so i pretty sure i have the TIP sensor wired right?
here a video of how it sounds when i try to crank it

 

tryed searching "won't start" did get any info on what it could be

 

It sounds like it needs gas. any fuel in the tank? What has changed form the last time you had them off.

 

see thats what i thought but it's got plenty of gas in the tank and the fuel pump is coming on so? and i haven't touched any except the headlights

 

sup bro. it sounds like the fuel pump does prime. did you unplug your tip over sensor? is it bypassed at all? ill call you in a bit

 

the tip over switch wouldn't let the pump prime but im not sure from that clip if the noise im hearing is the pump ....

so i would check all the safety switches [tip sensor, kickstand, clutch ] and the fuses

 

yah the pump is coming on, im gonna try all the safety swicthes and the fuses

 

all the safety swiches and fuse were fine, what else should i check?

 

check the fuel regulator. mine went out and it sounded just like that! this is a pretty common problem on the f4i's

 

check to see if it's getting spark

 

i know another common problem with the f4i is the diode in the ignition going bad but i think that also wouldn't let the fuel pump prime ...

 

i know its getting spark, where is the fuel regulator located? i'm new to working on bike, oh and how would check to make sure its work right?

Thanks

 

id call you but in fucked up right now! haha.. the fuel pressure regulator is on the left side of the fuel rail. it kinda looks like the ones in our cars. ive read that if you unplug the vacuum hose or something like that and gas comes out its bad. some ****. OMR could probably chime in and give exact details.

 

i heard sometime kickin it helps

 

spray some carb cleaner in your throttle boddies, if the bike tries to start, then you know your having a fuel problem. the regulator is on the left side, just follow the line from the tank. i believe it is held on by two 8 mm bolts!

 

thanks crazy636 , sprayed some carb cleaner in th TB's and it started up, i let it run for a min or so then turn it off to see if it would start again and it did but it's throwin the FI light, so how do i check the fuel regulator?

 

i would just buy another one and put it on! im pretty sure its only two, 8mm bolts. you will leak gas everywhere, so make sure you have something to pinch off the fuel line when you take it off!
