The engine had been stumbling and seemed only be running on one cylinder for the majority of the time and the check engine light would come on after about 15 min of riding. It got really bad so I took it to the Harley dealer to have them read the code and diagnose it for me. They told me that it is the fuel pump and possibly the O2 sensor as well. After they tested it they couldnt get it to fire so I trailered it home. When I got it home I pulled the plugs and they were black and wet. I installed new plugs and I can get it to fire now but it wont stay running and it runs pretty much just on one cylinder. The thing that puzzles me is that the pump engages and primes and sounds fine. My question is do you think its really the pump or what do you think it is before I go and spend the time and money for the pump. Thanks | ||

i do not know much about that but what about the injectors? | ||
| Snafu5962 |
the guy told me when i bought the bike a few weeks ago that he had just gotten them cleaned but who really knows... | ||

Now you know why "i" tell you BUELLers to get the FACTORY SERVICE MANUAL and PARTS BOOK for your YEAR/MODEL BUELL and be your own MECHANIC !!! If you want the HELP "INFO" how to pull your CODES, just PM me for a copy ... If you have a bad rear header exhaust gasket it will confuse your O2 sensor ...

ahh i c u r from york pa.. i im over by easton.. i have ecmspy cable/ and laptop. | ||

Did the dealer check the fuel pressure? What is the pressure? Should be near 55lbs. Low fuel pressure will set O2 codes also. | ||

01x1: i am from york but im away at college in Slippery Rock, Pa but if i cant figure things out by next weekend i will bring her home and hopefully link up with you. bpt: they said they checked it and it was at 3lbs. we all know dealers lie to get you to spend money thats why im asking before i buy. | ||
| 01x1buell |
snafu i have no idea where slippery rock is, and yes if you need a cable just pm me and i am sure i can meet up with you. | ||
| Snafu5962 |
Update: i sprayed starting fluid on the front and rear intakes and the bike runs well when i spray the front intake indicating the seal is bad so the H-D dealer lied to me. where is the cheapest place to order seals? | ||
| Buellistic |
INTAKE SEALS Class 101, just PM me if you want a copy ... | ||
| Snafu5962 |
PM sent. not sure how to check my PMs if u send one though because I am new here and never got one before... | ||
| Snafu5962 |
Just installed new seals as instructed and I'm still having the same issues as before. The bike will not run on its own. I'm totally mind boggled by this point so I guess I will be trailering it 5 hrs back to to get to 01X1's ecm spy. 01x1 i just sent you a PM | ||

Your bike was running lean as a result of your seals and ECM "learned" and applied a bunch of fuel to overcome the lean area making your bike foul plugs. O2 sensor code then for over rich. Bad fuel pump will make bike real lean.It would never even fire at 3 psi. Check your AFV, betting it is way above 100,needs to be reset so bike can run properly. | ||

justin, damn i thought you where closer turns out you are about 120 miles from me.. i e mailed you. | ||
| Snafu5962 |
I tried just the fuel filter and I still have the same results. Working on ordering a fuel pump now and going from there I guess. I'll keep everyone posted. | ||

Since the plugs are black and wet, it would seem the pump is working. I might choose to look elsewhere, for the time being. As an aside, fuel injection systems are so prevalent now, there should be lots of places nearby to allow you to get a second opinion. As to the running issue, with the light coming on after running for 15 mins or so, look into checking/replacing the engine temp sensor. If they get into a pre-fail mode, or they 'shift' calibration, they can cause all kinds of running issues and throw codes, none of which will be an ETS code. | ||

sounds like I need to buy ecm spy or find someone in the Pittsburgh area that has one before I do anything else... | ||

If the engine trouble light is coming on, you can read the codes without ECM spy. All you need to do is short two of the pins in the data connector and turn on the ignition without starting it up. http://bcrider.com/DDFI.html You can use a jack knife to short the pins. Just don't bend them! If you had an intake leak for a few miles, your ECU will crank up the fuel mixture to compensate. If this is the case, get it on the highway to let it relearn. | ||
| Snafu5962 |
it starts up but shuts right off. I cant even baby it to run anymore so taking it on the highway or even getting it to throw a code is out of the question. I am mind boggled and dont know what else to do other than get ecm spy unless someone can shine some telekenesis on my bike  | ||

i wish i could help you man, hope you get it fixed soon, and again if you come home again let me know ahead of time and i can do my best to free up time to help... sorry about last time i had to get my truck fixed( u joints blew out ) had to replace all of them. | ||
| Snafu5962 |
01x1 I might just make a special trip home to link up with you soon maybe in the beginning of November sometime because even if i get ecm spy i dont know how to use it and will prob mess my bike up worse | ||
| 01x1buell |
ecmspy is pretty simple, i bought mine off of ebay and it came with a tuning guide and basic instructions and i also got alot of help from guys here.. just let us know how everything works out. | ||

Just because you put new intake seals in doesn't mean you fixed the leak. Easy to re-do just to make sure, when you get the chance. DO NOT BUY A NEW FUEL PUMP! When I bought my '00 X1 last December, it too was running on one cylinder. Turned out to be the engine temp sensor and then I also replaced the O2 sensor. Here is what you want to do to read the codes. Your data connector is a 4-pin connector. It is located in the steering head area and has a gray rubber boot over it. Position the connector so that the connector lock is facing to the 12 o'clock position. Then, jumper the right two pins together. This will allow you to observe the DTC's or better known as the Diagnostic Trouble Codes, at the check engine light in your tachometer. Once you've done that, turn your ignition switch to RUN and your kill switch to the start position BUT DO NOT START THE BIKE. You'll now observe, via the check engine light, a flashing code that will tell you what, if anything, may be giving you DTC's. Make sure you have pencil and paper handy and write the codes down. The first sequence will be several flashes followed by the FIRST DIGIT of the code (count the flashes and record), then a pause followed by the SECOND DIGIT of the code (count the flashes and record). WRITE DOWN THOSE TWO digits and wait to see if you have any more DTC's that count out. Mine had two. You may not have any. Let us know what codes, if any, you record. Another thing to check is your engine temp. sensor wiring for fraying. On your '99, the ET sensor is located down through the rear head rocker cover and the wire that comes out of the rocker cover sometimes chafes enough at the "bend" to cause a short, resulting in a poorly running bike. Report back when you check your engine temp sensor wire for chafing and have jumpered your data connector pins and read out any DTC's you may have. By the way, I'm at work or I'd give you all the DTC codes but the service manual is home. (Message edited by two_seasons on October 18, 2011) | ||

the engine temp wire looks pretty haggard. I will jumper the pins and see what comes up tomorrow or thursday sometime and report back. thank you for the helpful info. | ||
| Snafu5962 |
wait, what im thinking of may not be what you are talking about. The wire im looking at is right next to the rear spark plug and is wrapped in a weaved jacket... | ||
| Two_seasons |
That's the one. Black nylon weave of some sort. It goes down into a recessed hole on top to the sensor. | ||
| Snafu5962 |
I jumpered the connectors and it looks like its throwing code 11 which is the TPS. What should I do now? | ||
| Two_seasons |
I'll check code 11 when I get home. | ||
| Snafu5962 |
or do I add the 2 codes together making it code 23 which is the front injector which I have been suspecting was the problem most of the time? | ||
| Snafu5962 |
well I was reading the how to on getting the codes and it seems that maybe all im getting is a bunch of flashes and no codes. Im confused and frustrated. I guess I just need to give it up and get ECM SPY or something  |
