Default 2002 Road King Classic Won't Start!

Hi all,
Thank you for looking at my post, I really appreciate it. I have a '02 Road King Classic with stock TC88. It has always started and ran really good, but last year I didn't ride it at all and probably only started it up two or three times the whole year. Now I cannot get the engine to turnover at all. Here are some details of what has/is occurring:
1. I put some fuel stabilizer in the tank in mid 2022 and started it up two or three times for the next 12 months.
2. Earlier this year I decided to take it for a short ride and it started right up but was sputtering a little bit
3. I took it for a short ride but had to turn around and come back because it was sputtering so bad and had very little power to it. I was not sure i would make it back but I managed to get it back in the garage
4. The only think I could think of is that the gas was spoiled/bad so I drained the gas tank completely and put fresh gas in.
5. Now the engine will not start. The battery is strong but the engine will not turnover.
Does anyone have some ideas on what the issue could be? I did put in fresh spark plugs but I haven't tried anything else. Any help sure would be appreciated.


Thank you,
Todd

Soooo:

1- Turn the ignition switch on, you hear the fuel pump build pressure and all the lights come on, including the neutral indicator

2- right handlebar switch to run

3- press the start button and … ? No response of any kind?

Thank you for your reply. The engine cranks and cranks but it just will not start. Sounds like a healthy engine just won't start.

Do you hear the fuel pump pressurize?

If yes; pull one of the spark plugs and lay it against the head, crank the starter and observe if you have spark

I definitely hear the fuel pump. I'll give that a try, I really appreciate it!

People have used "turn over" several different ways, so a clarification is needed. Does the starter fail to spin the engine at all? If not, there are many things to check but not worth going into if that is not your problem. If the starter spins the engine but there is no combustion, there are many different things to check not involving the starter itself. So, does the engine spin when the starter button is pushed? If it does, does it seem to have the normal speed of rotation or does it seem sluggish and slow?

How old is your battery, and do you keep it on a maintainer?

Thank you for responding. The starter sounds/feels strong and the motor is spinning well. Sounds solid and strong and quite normal. The battery is about a year old and i keep it on a maintainer. The battery sounds very healthy.

Very often, when an engine cranks strong but won't fire up, it can be the crank positon sensor. I know the rule of thumb is to go back to the last thing you did, but you already did that.
The good news is that it's cheap and easy to replace. The better news is that you can test it first. There are a number of Youtube videos on how to do this; it's a matter of testing resistance (ohms) with a voltage meter.
Good luck and report back.

A "shade tree" step from here would be to remove the air cleaner and squirt a little fuel into the intake, then crank the starter. If the engine fires (attempts to start and then dies when the added fuel is exhausted) you have a fuel feed problem. The SNEAKIEST malfunction that causes that is the fuel tank quick disconnect. They sometimes dislodge a little and shut off the fuel. Disconnect it and reconnecting usually starts normal fuel flow again. If that doesn't do it, the sitting for a year may have plugged up the fuel filter and/or the injectors.

If there is still no attempt to start (no combustion pops) the problem is most likely ignition.

Great advice here, and I would suspect that btsom is right. Since the no-start presented after you disconnected the fuel fitting (assuming you did) this would be the place to start.
