Hey. New to the forum and HD ownership. I picked up an anniversary deuce and it has been running fine. Went to work the other day no issues and when I went to leave the bike wouldn't start. Just turned over. Checked the fuses, and checked the spark at the plugs. No spark so I replaced the coil, plugs, and wires. Still no spark at the plugs. Anyone got any suggestions before I take it to a dealer? Thanks

 

What year is the bike?

 

2003 FXSTDI. All lights and fuel pump work. Switches at the handlebars are fine too just checked those.

 

Crank position sensor is a possibility.

 

Make the 'kill switch' is in the run position. And that the FOB battery, if you have security, is not dead.

 

I just went through nearly the exact thing. Mine would crank in the mornings and not fire. After beating my head against the wall telling myself it couldn't possibly be the battery.....it was the battery.

I'm not saying this is your problem, but if battery voltage DURING CRANKING falls below a certain threshold.....no fire to the plugs.

Take the battery out and have it load tested. At the very least, its an easy way to confirm or eliminate that possibility

 

Usually, the plugs won't fire on a FI fuel injection unless you leave them in and ground other plugs clipped on to the head. Harley senses the resistance of the compression. Be sure to use correct Harley plugs. They are a little resistance difference in so called substitutions. Is the fuel pump running the two second timer run when you key on?

 

Yes. The fuel pump runs. I can hear it and smell gas when the plugs are out of the head. The plugs are HD specific for the bike. Gapped to .040

 

Add a signature line to your profile on year and full model letters of your bike for the future. It wont crank or prime with 'kill switch' off. 2003 has push button FOB, so it's not that. Does it have a aftermarket tuner?

 

It does have a fuelpak. I unplugged it from the system and plugged the ECM back up to factory and it still won't fire.
