Posted this before but I guess with the site down it got lost somehow. But here is the skinny, went out about two weeks ago tried starting the S4 when it was cold. All it did was sputter when you first started to crank it over. I wore the battery down so I charged it. Went out Saturday to try and start it same thing all i got was a sputter once you tried to crank it over. The kill switch is in the right spot. pulled a plug to see if I was getting spark, I was getting spark. I can smell fuel so I know its getting fuel. So any ideas to help or to go by.

WhRe: S4 wont start

Not sure if this will help or not, but I had the same problem. Make sure all cylinders are getting spark, my connector fell off one of the coils to the #2 cylinder and the bike wouldn't start. A good indicator of this is the tach which won't work if this happens, you should be able to see the tach jump a bit when turning the bike over. Other than that check all your injector connections. Have you recently done work on the bike?

Good Luck!!

well, are you checking your battery with a volt meter? maybe its the charging system. My bike needs a strong battery to kick it over when its cold. I have an Oddessy battery and I keep it on a tender when its in the garage.

Oh, I just re read your post, did you not get it started the first time, and then it still would not start with a charged battery? If so, make sure your battery is getting to full charge and holding.

It didnt start after I drained the battery. I put it on the tender and it has no problems turning over, but still wont start.

I had some prolems with my S4 not starting a while back and came to find out it was the dam security key.
Guess you've already checked this ?.

I think that after a long winter's rest, the extra urgency of an auto-battery jump is a good thing to try.

Woke my bike last Sunday. Thought she wasn't going to start either. The battery was almost spent when she kicked over and ran like been out just the day before.

It has been in the 50's here in Maryland. Tried the jumping it off with the truck but still nothing it will just crank. When I first tried it last week it would sputter on the initial crank but it wouldnt catch. Now it doesnt even do that.

Do you have only 1 key up at the ignition.2 or more keys will confuse the imobliser. Be sure to have only 1 key. Tim

i was told to NOT stick the red key in the ignition under threat of torture by the duck dealer. I forget exactly why, but maybe to reset the computer. or some such crap.
I just remember the salesman said If I stick the red key in the ignition it will cost me 1200.00 for new computer. 2002 s4. Was I fed a line??

The 2 black keys are for normal bike operation the red key serves the same functions as the black keys also it is used to reprogram the black keys if needed (page 14 owners manual). If you loose the red key and have imobliser problems that might cost you the 1200 that the dealer was referring to.

If the bike is cranking, the immobilizer discussion is irrelevant to this question.

Given that your bike did sputter last week, but not catch, you may have loaded up the plugs. I'd pull them and wire-brush them if they look black. Then reinstall and try again.

Used a wire brush cleaned off the plugs real good thought I had cleaned the plugs off good enough before but evidently I didnt. Cleaned them up, put them in and it fired up.

Only 800 miles on it original plugs took the wirebrush to them. Put them back in and it fired right up. Guess I fouled them when I tried to start it around 30 degrees. Some new plugs on the way.
