Long process and post
I did think about the inline fuel lines and did check them with some air pressure, but couldn't really see any thing. So I made sure the tank was full and still won't run more then 5 seconds.
I will check the o-ring next. Every time I have taken it apart there is always gas there, but never checked the O-ring. Didn't know there was one.
I was hoping putting in the clean map again would take care of the lean part to the gas. The map is # 769 cause as soon as I got the bike I put in gear drive and Reinhart tru duals and big sucker air filter.
Good info and will check it all out

Did you pull each spark plug to check if they're getting a healthy blue spark? Friend of mine had a similar problem albeit on a Yamaha, surging power, wouldn't start, etc. I pulled the plug and grounded it while starting the bike, observed a weak yellow spark, put in new plugs and voila, problem solved! Even though you've changed your plugs, perhaps they're not getting enough voltage or current from somewhere down the chain.

+2, same exact thing happened to my 2003 Road King. It developed a small hole in a fuel line, and it continued to get worse and worse then finally ran so bad you couldn't ride it. Replaced the fuel line, which HD says is a very common problem on the earlier FI bikes, and good to go. I guess the line after the pump lays on the inside of the tank and ends up rubbing a hole in it over time.....Cliff
Just took out the O-ring in quick disconnect, the one that is attached to the injector tube. I didn't know if there is an oring on the tank side of quick disconnect. The bike has wanted to run more times as if I hit the starter button 10 times it now wants to run 6 times compared to one b4 I messed with the o-ring. Will keep trying though.
The air leak in the intake was something I thought of just wasn't sure where to start looking, I thought of this cause if I plug the IAC motor hole with my finger it seems to throw out a different noise that makes me think it wants to run, but that is still up in the air though it was just me goofing around.
Couple of questions.
1) what if fuel pressure shows to much what would you do?
2)what if fuel pressure shows to little what would you do?
I don't have a fuel pressure gauge or the attachment to make it work to the bike, if it has to be I will go get one, but thought if I knew what to look for on both questions above I would start there also
Here is another thing I'm getting a lot of back fire from throttle body a lot of popping and all the chrome around the air filter is completely black, I wiped it off.

I will check the spark plugs again. All I did last time was take them out, left them hanging and turned the bike over. I don't know how often the spark should appear on each turn over or a sequence of turn over, but did see a spark every couple of trying to start it.
Here is something I just came across, might be of interest. I turn the bike on let it go through the fuel pump noise etc... try to start it and it tries to run for a sec if I don't turn it off and keep trying it takes several tries to get it to try to run, but if I turn bike on let it run the fuel pump try to start it and it tries to run then turn it off and then back on and let the fuel pump make it noise and try to start it, it tries to run, every time I do that scenirio

I'm not going to say just cause I checked something it isn't the problem. I may buy a new fuel tube that connects on to the injector tube. I took that o-ring out and may have put a few knicks in the piece that fits on top of the spring. I see two lines in it that may have been when I was pushing it down to get to O-ring. Side note with all the O-rings I have messed with on my breathing air compressor and my regulators for cave diving (hundreds) this one on fuel tubing was interesting.
Once you turn the ignition on and hear the fuel pump wind up the bike should start and run. If it stops running and you cycle the ignition again you should NOT hear the fuel pump wind up again IF the bike is maintaining fuel pressure. On a normal shutdown the system pressure will maintain around 55 psi for quite some time.
Cycle the ignition 5-6 times in a minute, if the fuel pump winds up every time you have a pressure leak somewhere inside the tank.
