Just picked up an 03 919, now it's not starting..

I am new to this forum, but have browsed it quite a bit.. Recently I bought a 2003 Honda 919 with 15k on it. It ran without problems and the previous owner did regular maintenance. However when I get something used I like to get it on my schedule. I did an oil change, no problems. Since its close to 16k I wanted to change the spark plugs. Everything went well except plug three, the rubber boot was damaged, but still clicks on to the plug, new boot on order. When I put everything back it just turns over and will pop every few seconds. HereS what I have done so far to trouble shoot and no luck:

1. Checked that the coil spades are connected and that the correct coils are hooked to the correct cylinders (1-4 on one and 2-3 on another).
2. Triple checked spark plug gap and even tried again with old plugs, same results.
3. Checked the spark to each plug, and every one has a good spark.
4. I can hear the fuel pump kick on when I turn key on. I
5. Checked all fuses and electrical connections, also fully charged the battery

Does anyone have any ideas of what else to try? The bike was running fine before this and the plugs that came out 2-3 were not fouled. I did notice while takin the plugs in and out after turning engine over there seems to be a small amount of fuel on the bottom of the plugs.. Any help would be greatly appreciated! Thanks

hmm the only thing i could think of is that you have the coil thats spost to fire 1 and 4, hooked to cylinders 2 and 3... and visa versa.

if i remember correctly (but dont quote me on it... i can look at my bike if need be) the coil thats on the clutch side of the backbone... fires 1 and 4.... and the coil centered under the frame 2 and 3.

as even if you did have one bad wire thus only 3 cylinders firing... it would run... hell the 919 will run on 2 cylinders.

I know you said you checked it but double even trippel check the coil wires. 1-4 should fire first then 2-3.

Dodge2589 03-25-2012 10:50 AM

I have the coil on the clutch (left side) to 1-4. All stock except exhaust and a speedometer corrector..

Check the fuel pressure regulator?

07919Dave 03-25-2012 01:09 PM

Oooohh that's a common one. Any else have theirs go out? Is this the same symptom that Dodge is having?

ideajones 03-25-2012 02:03 PM

Check the kill switch? Guess if it pops that's not it.

Dodge2589 03-25-2012 02:07 PM

Have not checked the fuel regulator, where is it located? And by kill switch do you me the one on the handlebars? Thanks

ideajones 03-25-2012 02:32 PM

Yes but if your getting spark that's not the problem.

nd4spdbh 03-25-2012 02:48 PM

its possible if its the FPR.... try cranking it while holding the throttle open a bit.

But i still believe its just a small mix up with the plug wires on the wrong plugs.

HeliMech 03-25-2012 03:00 PM

Its gotta be the firing order, it is very easy to mix them up. They are routed in a very unnatural order, it goes against common Honda logic. :laugh:

Dodge2589 03-25-2012 03:54 PM

I have traced the plug wires several times, the coil on the left side goes to 1-4 and the coil in the middle goes to 2-3. No luck with giving it gas..

Dodge2589 03-25-2012 04:37 PM

I also tried cranking with the throttle open, and also the procedure for starting with a flooded engine. I will say that when normally trying to crank it pops one after another. When trying the flooded engine starting method (holding the throttle at full open) the popping stops and clear smoke comes out of the exhaust.. Still no luck though

Januik12 03-25-2012 04:55 PM

The plug wires are numbered 1 to 4, they are really easy to put on properly...that's cant be the problem

Dodge2589 03-25-2012 05:22 PM

Just check all electrical plugs... I'm stumped.

07919Dave 03-25-2012 05:59 PM

Try doing a search for the FPRand see what others have done. Dumb question but are you in gear and trying to start it with the side stand down? or it wouldn't turn over either like that, huh?

rmb 03-25-2012 06:00 PM

Are you absolutely sure your battery is good and fully charged?

Dodge2589 03-25-2012 06:06 PM

I did read a lot about FPR, but it seems like even with these problems it should still start... As far as the battery goes my battery did die and right now to turn it over I am using my durango as a jump vehicle (not started). DO you think this wouldn't be sufficient?

Bike is in N

Charge your battery overnight and try again. The 919 is known for being very finicky with battery voltage.

nd4spdbh 03-25-2012 06:28 PM

hmm... sounds like you got em completely backwards... try putting the 2-3 plug wires on 1-4 and visa versa. tho it could be your batt.

Just take the 919's battery out of the loop completely, and run straight off the cars batt (no need to have the car on)

Dodge2589 03-25-2012 06:41 PM

Bam that was it. I switched 1 and 2 and 3 and 4 and she fired right up. So I guess my middle coil controls 1-4 and the left, 2-3..

Dodge2589 03-25-2012 06:42 PM

Thanks for all the quick assistance!!!

called it!

thing probably fired right up and purred like a kitten.

technically it should be the coil on the side of the frame firing 1 and 4. and under frame should be 2 and 3... as per the service manual and my bike (just checked)

its very possible the PO unhooked the leads from the harness to the coils and swapped em accidently... no biggy... either way works so long as the properly firing coils go to the proper cylinders.

Its just you PROPERLY put back the plug wires... and in doing so swapped the swapped order that made em work.

Dodge2589 03-25-2012 07:44 PM

Yup just gotta get my batt. charged back up and i'll be good to go. Thanks again

07919Dave 03-25-2012 08:48 PM

WT solves another problem. Now get that battery charged and enjoy the spring!!
