So I went on holiday for about a week and when I came back bike won't start. Starter turns, engine pump pumps, spark plugs are sparking. I have noticed now after a few tries that the fuel line is shooting out the top when the pump gets pumping. Tried to dry it out by unpluging the power from tank and turning it over a few times. Still no fire. Have the tank and airbox completely off bike right now and am awaiting suggestions. Thanks, and I appreciate the help.
I'm confused by what you mean when saying that the fuel line shoots out the top. The top of what, and is the fuel line coming loose?
Have you checked your battery voltage? The battery could have enough juice to run the starter and coils, but it may not have enough for the ECM to operate. What do you instrument lights and gauges do when the ignition and kill switch are on?
All gauges and headlight turn on fine. The gas shoots out between the connection from the fuel line to the gas tank. At the connection almost like the line is overflowing.
Before I had gone on my trip I had been having issues at startup where the bike wouldn't stay running on the first crank. It would cut out and then on the second startup it would stay running with a little pull in the throttle. I had thought it was that I needed new sparkplugs. So new plugs are in now but no startup. Since I was gone for a week is it possible that something could buildup inside the gas line? This bike is an every day ride so it rarely sits for more then a day. When I get home I'll try to remove the gas line and see.
It is highly unlikely that spark plugs would cause the running issues you describe. Spark plugs rarely fail over night, and I've never seen four plugs totally fail at once, causing such running issues. You are more likely to start seeing misses for some time before major issues occur. Of course, fouled plugs can happen all at once, but there would be issues other than the plugs if they were fouled.
What you describe could be a number of issues, and I'd start with looking into the fuel leak. The plastic quick connectors commonly break, so that's where I'd look first. I'd then check the fuel hose orientation, as crossed lines will cause back-pressure and starting issues.
I agree with Bombfactory. While it may not be the fuel quick-connects causing the problem, it certainly is not a good thing for fuel to be spraying out all over the engine! Also, definitely make sure that the hoses are connected properly (white to white, red to red...)
I replaced my quick-connects with stainless ones (bout $50).
Interestingly enough, not all the male and female connectors share the same color (i.e. w/w, r/r). Many dealerships switch the colors when changing the male connectors to aluminum, maybe to tell that the change was made or something. So many fuel hose hookups run red/white, white/red.
If the female connector colors are factory original, the left hose from the fuel rail (feed) goes to red, the right hose (return) goes to white. Or one could replace the colors, like you've done supaevan, to where they match up and make sense.
I'm sure it's something really easy but I can't figure it out. Going to take it to the shop Thursday. I'll let you guys know what the problem was when I find out. Thanks for all the help. Man I'm itching to ride. Been almost two weeks. Thanks again. Glad I found this site. I was a daytona600.org member and went to find it was gone. Here now, thanks!
I happen to have a picture of the bottom of my D6 fuel tank.
Think it might help in identifying your problem as people seem to think the connectors on a D6 are the same as those on an S4/TT
That is of course assuming that mine is standard and hasn't been changed
For what it's worth, the white plastic connector is the power for the fuel pump, the brass elbow is the main fuel connection which goes to the TB's, the 2 nipples on the left of the photo, one goes to a drain tube, the other is not connected to anything (at least on my bike)
The main fuel connector on the female side is a black plastic quick connect (button push)
Yes, Hippy, you're correct; the later model S4 and all D6 have only one fuel connection at the pump, whereas the earlier S4 and all TT600 (from what I know in oem form) use two connections. My cross-line comment is a brain misfire.
It could very well be a clogged fuel filter? Chances are that the shop will let you know that many expensive things are at fault regardless of validity
Took it to a shop that usually doesnt charge to much and treats me well. Still have no idea what it's going to cost. I took it in last Saturday finally and here it is a week later and they haven't even started on it to my knowledge. Told me they got a lot of bikes in. Which there were a lot there. Everything from kwaks to ducs being worked on. Going crazy not being able to ride. Been three weeks not riding other than riding my buddy's supermoto around the publix parking lot for a fix. By god I hope they're done soon!
The fitting on your bike is like the fitting on my 675. They are a PITA to get seated, so it is possible the fitting just wasn't fully engaged. I had the same problem at one time. Some, like mine, are more of a problem to disconnect and reconnect than others. Yours may be one of the ones which doesn't like to get taken apart or reassembled.
