No start, warm engine

[Tcfdvm]

Hello all...looking for help. Recently, my 2019 Goldwing Tour DCT with 6,400 miles on it has trouble starting. This ONLY occurs after the bike has been ridden for over 45 minutes (highway speeds) and then sits for 20 minutes or so before starting it up. The engine turns over, it runs poorly for about 2 to 5 seconds, then stops. At first I thought it was a battery issue (original battery was replaced last week), but it still continues. I only use 91 to 93 octane fuel. IF I let the bike sit for 2 plus hours, it starts fine. Jump starting it doesn't help, either. What's really a mystery is that this only happens when I'm riding away from my home into the city for errands or work. It's never happened after riding the bike back home and garaging it (I've gone out 20 minutes later to start it and starts fine). Any ideas? Suggestions? Because it's inconsistent, I'm hesitant to bring it to the dealer yet. No matter the ride, it'll always start if parked in my garage. Not sure if coincidence or cause, but if left outdoors in the sun, that's when I have starting issues (of course, always away from home).Thanks for reading and any info. Tom

You might want to try the recommended fuel. Many GoldWings don't like premium as it is not as volatile as regular. The engine was not designed to burn high octane fuel.

Thanks, Rambozo. I'll give that a try. Owner's manual does state 86 or above octane. I didn't realize there was a cutoff.

Wanna semi-educated guess?

I think you have a computer glitch.

Especially since it seems to be repeatable.

Disconnect the battery, wait 30 min, reconnected (+ first) and start it without touching the throttle.

Let it run unmolested until the fans come on. The important part - DO NOT TOUCH THE THROTTLE!

Shut her off and restart with no throttle.

You have reset the ECM. Hopefully, that solves the problem.

Seems like a reasonable option and easy to do. Thank you, Kwthom

If that does not correct the issue, you might then need to arrange to have your dealer look at it with a scan tool while the bike is in the malfunctioning condition.

Luck to you!

I agree with Rambozo on the fuel. Besides wasting fifty cents per gallon on fuel, you are not helping the engine. Higher octane does not mean faster burning, it means harder to ignite and is designed for high compression engines to prevent pre-ignition commonly called engine knock. Lower compression engines do not need the extra help to prevent this and there are no benefits from it.

Be sure your battery connections are clean and tight. If all good there, the next thing to do is to have your battery professionally tested. Keep in mind that many think that replaceing the battery is equal to or better then having it tested. In either case, new or old, the battery being used need tested to prove that it deserves to be used.

As for gas ... for proper information on how to operate, maintain, and care for your Wing, follow the recommendations as listed in the Owner's Manual.

[Tcfdvm]

Dealership thinks it may be a bad fuel pump. As the engine gets hot, something about the fuel pump doesn't operate as it should until the engine completely cools. I'll know for sure when I take it in in a couple of weeks.

Have you tried opening the fuel cap when it’s running bad and stalling to see if it’s vapor locking?

Hello everyone.
Last September my brother-in-law had the same problem with his 2019 Goldwing. At first we changed the battery, then we thought it was dirty gasoline and cleaned the tank, but the problem persisted.
We finally found out that the problem was the faulty gasoline pump.
Once it was replaced, the problem no longer represented itself.

Just a thought but do you park the bike differently in town Vs at home? Side stand and then mainstand or vice versa? Just musing.

Hi All, It turns out the problem was a defective fuel pump, nothing having to do with octane or battery. Repair was covered under Honda's warranty. Apparently there was a "recall" or TSB that I wasn't aware of until dealer brought it to my attention. Thank goodness it happened while under my 3 year original warranty. For everyone's benefit, I did try to load a video, but apparently was a few seconds too long, so can't show you exactly what the bike did/didn't do while trying to start.

You're right on, Kalsich! Same problem with mine. Hope he had it still under warranty.

Thank you for coming back and giving an update.

To tcfdvm and to all other Forum users:
Unfortunately, here in Switzerland the factory warranty is only 2 years, so replacing the fuel pump was at our expense .
However the important thing is that the problem has been solved.
I send everyone my best wishes for a peaceful Christmas, and may 2023 allow us to fully enjoy our Goldwings.
