Please Help! Any assistance would be greatly appreciated
Last year in September, in 2011, I rode my bike 110 miles to the beach. During that time it ran fine from my home to the shore rental, next day while on the beach a quick but soaking rain storm came thru and wet the bike 1-2 inches of rain hit the bike. Bike cranked over but wouldn't start, wound up towing it home on a trailer. I have not been able to start it in 7 months, since that day I have drained the fuel, oil & filter replaced with fresh ( no trace of water in gas or oil ) all fuses were good yet I replaced the fuses anyway. Replaced plugs, replaced the battery & reads12.8 VDC. While bike is in Neutral, I OHM'ed out the side stand switch from the connector side to the stand- OK, I pulled the diode and OHM'ed out -OK, While the Air filter was removed. In addition, Ignition Fault codes are as follows; 1 - 7 - 9. The 1st flash doesn't appear to be a half second flash yet it appears ( in my opinion ) longer than the flashes associated in the string of 7 and the string of 9, yet not the 1.3 sec flash thats required for a double digit code I have a 3 mg., 19 second video which I will attempt to attach. That being said, I removed and installed a new pulse generator, per procedure in the Haynes 4060 CBR 954 Manual. Also The bike is equipped with a Jardine Exhause with a Power Commander. I did attempt to remove the wiring of the power commander out of the scenario thinking this could be the Issue? Is there any way to test the ECU
No change I am beyond frustrated, Please HELP????

The IAT sensor & ECT sensor were not the issue as they popped up due to the Air box removed ( I THINK ) as those sensors needed to be disconnected while the airbox was off. during this time I attempted to start the bike by pouring a small cup of gas down each cylinder (Didnt work). Any way, I was thinking the 1 in the fault was actually the begining of a double digit fault making it 17 or 19, there is no 17 in my fault code definitions but there is a 19 = Pulse generator, which as I mentioned previously that I changed out with a known good one. I reinstalled the airbox re-connecting the sensors and cleared the faults. My baby still wont start and the faults stay cleared. I can say for what its worth, I am somewhat mechanically inclined and Im confident when I say that most problems will surface in an area that people are generally working in. Despite how carefull I am I starting to question everything that I have done thus the reason for posting this. This is the first time I have every done this in my life. Im over 40

Thank very much for replying. this site is a very awesome tool for help. I will pass the word. Again thanks in advance. '

When the airbox sensors are plugged in, does the code remain? You're right about there being no code 17, that's what made me lean towards codes 7 and 9.

No to you question re: the airbox reinstalled & I am in agreement with you however due to the way its cranking The Pulse generator seemed to fit, as I mentioned since the rain storm she would not start. it was running 2 hours before that very storm. Also I have a Jardine Exhaust With a TFI Pwr Commander, Removing all wires & traces of the PWR CMDR Same condition while attempting to start. (I did this under the assumption of the pwr cmdr getting wet.)

HWAP, while I appreciate you taken the time out to review my thread at the same time if I were in a position to do so I would however with that said my reply to your statement can be answered two ways, 1st: Welcoming a challenge is always a good thing especially when it gets accomplished, with assistance is good & without is that much better. 2'nd: A Motorcycle dealers hourly rate is absolute robbery, not to offend anyone that is a mechanic for a Dealership on here. Although young then, I was a mechanic back in the late 80s for 3 separate dealerships I'm somewhat familiar with their practices. A certain trust factor comes to play!
Anyone else out there that could offer some assistance? I would much appreciate it.

Yes sorry, I should have mentioned that. The pump does prime, Question for you tho? Does that eliminate the Key portion of the ignition switch. I believe Honda refers to it as HISS? I'm not 100% on the technical term. Do all 2003 954's come equipped with the Ignition "CHIP IN THE KEY" Safety feature? if so once the priming sound is heard, Is the "CHIP IN THE KEY" to the ECU portion of the equation eliminated?

I don't believe American bikes have HISS. If yours does, you'll see HISS written just above the ignition lock, and you'll have a key symbol and light on the dash.

Crazie929, yes I do infact have spark on all 4 coils however the spark that I see is a small dim like dash ( 1/4 inch or so) and according to the manual that I just re read again for a better understanding, i am supposed to have a bright blue ball ! Is this correct? If so I do not. Again this is began when the bike was parked after a rain storm

Th spark should b a small, but bright, arc. My 929 recently sat thru a severe thunderstorm that brought 70mph winds with rain an hail. Th issues I had was no turn signals or brake lights. Turns out water had gotten into th relays causing th malfunction. Air dried th relay an everything was good again. I decided to redo th main wire harness cuz mine is a streetfighter but upon removing all th "tape", I found moisture in th wire harness. Not that it caused a problem but I wouldve never figured to find moisture in those areas. I guess what I'm trying to say is that u might have water/moisture lingering around some area causing a short of sorts. Have u thoroughly cleaned all connectors? An by clean I mean checking for moisture an drying th little suckers out?

thanks for your reply crazy929, yes infact this happen over 6 months ago and to my benifit the bike sits inside a climate controled garage. I have taken apart connectors from the steering area along with below the gas tank in addition to removing the ECU protector and the connectors in front of that area. In addition, I sprayed a contact cleaner (CRC) the type thats made for corrosion in the plastic connectors. Still nothing. I may need to look into replacing the ECU or wiring harness

Have you sprayed any starting fluid into it? If you do, and it tries to start then, I would think its a fuel issue. Just my 2 cents. :rolleyes:

Yes I did try starting fluid Blues, and thanks for the reply, in fact, I attempted to pour approx an ounce of fuel down all four cylinders. that did not work. Based on my minor experience on bikes Im leading towards the week spark theory, And Im begining to believe that I need an ECU. Anybody have a spare working ECU for sale

Sorry, I missed the spot where you said you poured some fuel in.:mad:

My last guess before the ECU, would be to check the coils, since you said your spark seemed weak. Maybe they got affected by the rain storm and I have had coils go bad before...even new ones.

Sorry for the Late reply Blues as I was awaiting an ECU/ECM to come in as I decided to order one from EBAY. I have not replaced the coills however I did try and get spark off each one individually by attempting to start it on the frame. No luck on all four seperate coils. I thought what were the Odds? And of course, as my luck would have it, the ECU was not the issue. Please correct me if im wrong? the wiring issue is the only issue?

I'd have to say, it sure seems like a wiring issue from all you have done and the direction it seems to be headed.

I will check my manual and see if there is anything that might have been missed. :huh:
