07 990 fuel pump

Ok, so I just read most of the fuel pump related articles over on the OC Hall of Wisdom and still have a question. How do you test if the fuel pump\fuel filters are in fact a problem? Mine will turn over fine but never fire unless I spray a little starter fluid in the throttle bodies. Then it will kind of run for a few seconds. Is there a basic way to test? Mine has about 35k miles with no problems in the past. However, over the winter it wouldn't start after sitting for a month or so. Guessing the filters could be an issue with my miles.? Also, maybe it is my imagination but the sound it makes when you first turn on the key might have slightly changed since I road it last. I would guess that sound is fuel related.?
Any ideas or good threads anyone can point me to?
Thx Jim

I guess you could test fuel pressure with a gauge. But for my 2 cents worth, at 35k miles I would change the filters and pump just for peace of mind. I did this on my '07 before an Alaska trip last Summer. I got the pump and filters from Gefr, a vendor here on AdvRider--'bout $100 for all as I remember.

Good luck

start by replacing the filters. If that doesn't fix it then replace the pump

That would save you $60 if the pump hasn't gone bad yet. Otherwise, you're back in there to change the pump. It's only time and money.....

FWIW

Check the pressure. It is either up to correct pressure, or it's at zero.

Pop the quick connect loose, push in the ends to release the pressure from both hoses. Then re-connect. Now feel how 'squishy' the hoses are. Turn on the pump and feel the hoses. If they are very firm, it is probably ok. Still squishy, not ok.

Move on to the injectors next. They can get clogged. Take them to a FI specialist to clean. Like:

Thanks guys. I haven't tested the pressure in the hose yet but I will try that tonight. However, I need to get it on the road for this weekend so I went ahead and ordered a filter kit and rebuild kit off of eBay for $139. They should arrive by Staurday. Guessing if I don't need them now I will eventually need them. I looked up the Gefr guy and saw his replacement pump but he appears to be in Greece and it can take 3 weeks to get the part. So I decided against going that route.
Hopefully this is the problem.
Jim

Thumb Get

a filterkit from Gefr as well sooner or later you'll need it, and it's of no consequence it you have to wait a while to get it now.

Gefr gets parts to me faster than the local dealer does.. He is a real good guy to deal with.

Are you sure the fuel line quick release is fully engaged?

Fuel filter problems normally show themselves at high revs, not at startup.

Can you hear the fuel pump prime up as you turn the ignition on?

If you have had the tank off and this fuel line apart making sure it is seated properly is a must.

I haven't pulled the tank yet but I will when I get home. That being said it ran fine a month or so ago so I doubt they became dis engaged. Worth a check though.

I can hear the priming but it "seems" to be slightly different sound than I remember. Not sure if that means anything or if it is my imagination but it sounds kind of sickly.

OK I pulled the tank tonight. Unplugged and replugged and verified the connector is fully seated. Same thing after.

Yes verified the release.

Was also thinking that about the filter but thought maybe the pump itself could cause a no start problem?? Bought both since I had 35k miles without ever touching the filters. Figured it was time.

Yes I can hear the pump prime but does it sound right? Listen below. I have put 35k miles on this bike and something tells me it sounds a little different than when I parked it in late November.

Ok I tried this. It seems the tank side was a little 'squishier' than the bike side of the release. That being said I didn't see either side getting considerably harder after priming the system.

So what does that tell me? The pump isn't pressuring up enough? I bought a pump rebuild kit with filters from eBay. If I replace these parts would this most likely resolve the problem.

Here is the link to the kit.

Thanks for everyone that replied. Much appreciated. There is always someone that has been there before.

That doesn't sound like the pump. It sounds like your butterflies that are sticking. Check them and the ISC as well.

The pump noise in the background sounds normal.
