Every year we get calls from customers who are, or have been, stranded and their fuel injected Harley won’t start. If the bike doesn’t start at home it may not be such a big deal. However, if you get stuck out on the road, it can be a very stressful experience.

In this video Mike takes a moment to remind us of some simple things to look for when your fuel injected Harley won’t start. He also gives us advice on preventative maintenance that can be performed in order to avoid these situations.

The first, most important thing to remember when your fuel injected Harley won’t start is not to panic. Take a step back and think simple:

  • – Is your key FOB within range (models with security)?
  • – Is the rocker switch switched to RUN?
  • – Is the petcock turned to ON or RESERVE (carbureted models)?
  • – Is the jiffy stand fully up (on models with this safety feature)? Also, try starting in neutral for a model that may have a neutral safety switch issue.

For models with security, it is important to replace your key FOB battery annually. It is also important to always carry a spare key FOB battery. When replacing the key FOB battery, make sure that you install it correctly. Note the way you remove the old battery. Positive & negative direction is labeled inside the FOB assembly. We notice that, probably only, 50% of riders know their security personal pin code. This is very important. If your FOB is lost or damaged, you can enter your pin number and be on your way.

If your fuel injected Harley won’t start, it is also a good idea to invest in a spare crank position sensor. We have seen these sensors fail in, as little as, 20k miles. The $60 cost of a spare sensor is worth the peace of mind. It is also much cheaper than hiring a flatbed and paying for a shop’s labor charge.

Battery and battery cable maintenance should always be scrutinized over. Only use a quality, known good, fully charged battery. Make sure that battery cables are clean and secure on both ends of each cable. Battery cable and spark plug wire replacement is important preventive maintenance that is not difficult to do.

After trying some simple things, if the fuel injected Harley won’t start, you will have to begin to determine if the issue is electrical or fuel related.

Checking for possible stored diagnostic trouble codes can be helpful for steering you in the right direction. Also, a spark tester is a very cheap tool that can help determine, with certainty, whether or not you have good spark.

On fuel injected models, make sure that you can hear the fuel pump cycle when switched to RUN. If not, check your fuses.

As always, the best way to avoid being stranded with your Harley Davidson is to be diligent about your bike’s maintenance. Follow the service schedule that is provided within your factory service manual. Thoroughly perform every service procedure and inspection that is listed.

    My 2010 FLHTK has had a somewhat random problem that has happened 3 times in the past 5 years. After a ride (long or short), it would start but operate only in limp mode. The first time I was at a store about 2 miles from home and since it had been some time, I replaced the FOB battery as they had them at the store. No go. I limped home in 2nd gear and immediately started the basics as in this video and even pulled, checked, and reinstalled the fuses thinking there might be some corrosion on the blades. No go. I then pulled out the service manual to check for error codes and found one (can't remember but I believe it was throttle related). After clearing the code, the bike operated normally. It was 2 more years before it happened again, and then again the following year. One of these days I'll have to look into the root problem...

    I recently had my tank relined since the old liner started flaking and clogging the fuel filters. I also installed both new fuel pump and filter assemblies. after everything was installed and check for any leaks I started the bike. When I turned the switch and press the start button, fuel pump then started and stopped when fully primed. I then started the bike in nueltral, it started for a few seconds then it died off leaving a EFP code. can the code be reset?
