I bought an 03 Road King and have put 500 mi on it this spring. It has been starting each time as it should. I took a ride yesterday approx 50 mi, it ran good with no concerns and got home and 3 hrs later went to start and it just cranks. It has spark, checked fuses, unplugged tuner, fuel pump runs when turning on, check valve has fuel, spark plugs good, no check engine light on. Any help will be greatly appreciated. Thanks !

 

Check for codes. Likely the crankshaft position sensor.

 

I had similar problem with my 03, fuel line into tank, quick release not snapped on collar

 

You can try holing up on the fuel line connection on the tank while starting to see if it runs. If not try squirting a little in the intake. It should pop off a couple Rs. If it does, you'll need to check fuel pressure. If not crank sensor, tho you typically not get spark. While cranking make sure the battery voltage stays above 9.5 volts.

 

Yeah, my bad. If he's got spark, the sensor is probably good. More likely fuel issue then.

 

UPDATE: Issue was fuel line inside tank. Thanks to all that replied ! Appreciate it ! Thanks again
