Bike doesn't start after ECU replacement

[FJRGuy]

My dealer told me that my bike was failing to start after installing the replacement ECU. Don't know the details by they were calling in the Yamaha Rep for a solution.

Has anyone ever heard of this happening? Could it be a bad ECU? Or maybe a bad Dealer? :dntknw:

Ding! Ding! Ding! Ding! Ding! Ding!

You've earned the Bozo button!

Most likely a "high resistance open"

Either that or they didn't check the kill switch.

What, vs. a "low resistance" open? :blink:

If'n I was at the dealership, I'd put the original ECU back and see if it starts. Doh!

:huh: Inside the ECU? In the wiring?

Either that or they didn't check the kill switch.

:rofl: They are not that bad a shop!

Yup! That was done!

They probably forgot to plug the new ECU in

Wouldn't be the first time DAMHIK :blink:

And the result was... ?

If the bike works fine on the old ECU and won't start on the new one...

Well, gee. What could the problem possibly be?

Ask them to have the tech verify that each of the wires plugging in to the ECU harness are properly seated in the harness. If the tech pulled on the wires when unplugging the original ECU, one could be loose when he plugged the harness into the new ECU.

I experienced this when I did the Barbarian Jumper modification.

FJRguy/fellow Canuck....did your dealer "re-register" your key? I am assuming, they did not !! Remember, we have an immobilizer system that the Yanks do not have Your new ECU will not recognize your old key...you will have to take the "master" (red) key to the dealer for the procedure as outlined in the factory service manual. It takes all of 3 minutes...good luck with it FJRguy. :assassin:

I am once again reminded of the troubles we put ourselves through instead of shooting a few thieves! :angry:

Sorry about the thread jack, but that's the way it hit me this morning!

hmmm... maybe something not quite so obvious as a bad ECU.

Thanks for your input Fred. I do appreciate it! B)

It is a bad ECU. The ECU is badly programmed! I bet the next one they got would do the same thing!

To be honest I completely forgot you guys have the fancy schmancy immobilizers.
