Hey guys,
2002 F4i
I had a dead battery.
I charged the dead battery and the bike fired right up.
I received a phone call and hit the killswitch <10sec following aforementioned fire up.
After phone call I attempted to start bike again.
Bike will not start.
Bike just whines with no ignition.
Bike battery holds a good charge.
I proceeded to check the plugs (not fun or easy)
Spark plugs were not wet
QUESTION: Are these plugs fouled...Or do they appear to be fouled...Or is there something else I should check out?
THANKS!

 

Those plugs look fine to me; much better looking than the ones I pulled out of mine at 12K miles. It's always been my understanding not to use the killswitch to shut-off the bike, but rather, turn the key to the off position. The Honda dealer told me that using the switch repeatedly may cause it to become faulty, resulting in the fuel pump being disactivated. Seeing as the bike started fine after your battery install, and your last action involved using the killswitch, I would advise you to start troubleshooting it there.

 

The plugs are in very good condition, expected with fuel injection.

I bet it's some sort of electrical issue. Try to override your kill switch (unplug batter for any electrical work!!)

FYI, the basic method is to find the wire the switch is breaking the continuity to and jump it across the switch, bypassing switch. This is the simplest thing to check first.

 

Thanks Gevo, I am going to attempt that right now!

 

Hey Again,
Everything is sparking just fine, all plugs and all coils.
The starter motor is working great too.
I would assume now that this can have nothing to do with the killswitch, it operates, switching the fuel pump on and off ,priming...all the usual.
I sprayed some "starter spray" into the engine...nothing but some smoke puffing out of the exhaust similar to if the engine were to start.
After about the millionth failure to start I think I have finally killed the battery and will need to purchase another.
ANY OTHER IDEAS?
Thanks guys!

 

i dont know but mine is doing the same thing

 

hmm, thats tough then. It's not too many things that can so abruptly change the bike so it doesn't start all of a sudden. All the usual things don'e REALLY apply in this situation, such as air going in, oxygen sensor going bad, fuel pump/filter acting up.. Those thing you usually notice due time.

Look, to make the bike fire you need the spark, fuel and air. Now if you are certain the spark is proper and adequate (cause you may see some week spark and think it's working) then check your fuel system operation and air intake, which has very few moving parts.
The way fuel injection works is by sensing the location of the throttle body butterly valve (i am not sure if it's butterfly valve or other type of valve on these engines, regardless) and send that signal to the computer, which tells the fuel injectors to spray so much fuel in the cylinders.

You are not getting any error codes right? (does your model year have error codes?) cause it is a possibility that the computer is at fault, unlikely, but possible.

I'll see what else comes to mind about this.
You shouldnt have to get a new battery, you should be able to charge it again.

 

also, I believe you have a bank angle sensor, im sure there is a way to test if tht is working.

also, i read around a little, and it seems some people have had fuel pump relays go out on them, causing similar problem as yours.

 

No error codes.
I went to purchase a new battery but they tested mine and said it was fine.
I finally got it started today by jumping it with my car.
It took forever to catch, but I have since noon started/shut off half a dozen times w/ no issues.
Right before it originally started today i did spray some "starter spray" under the spark plugs and after 30-45 seconds of stuttered coughing (previously it did not even stutter) it fired up...So maybe I had bad gas?
Thanks All for all of your input!

 

gas is a major issue for me. I learned the hard way when storing a bike for a few months, draining the system is not enough. I have had to clean my dirt bike's carbs because of this. I use fuel stabalizer now for storage, it helps a bit.

Put fresh gas in their.. maybe some proper fuel injector cleaners to clean out some gunk.

glad it's alive!!!
