Hi temperature on dashboard, bike won't start, no error code display, fuel pump not activating - SOL

[i_ride_naked]

Hello,

my first post, but i would like to share the experience I had with a (simple) problem on my bike, because perhaps someone with similar problems might find this useful.

After winter, after I charged the battery, my beloved FZ6 didn't start. There was a 'HI' (high) temperature message on dashboard and no error code displayed. Fuel pump didn't start.

I searched service manual (around 600 pages) and no similar error was described. Of course I continued searching on the Internets in found out that some people experienced same problems but when they took their bikes to mechanic/dealer, they changed their locks, keys and ECUs - stating it could be the immobiliser problem. Then I found some hints that it could be faulty wiring or lose connectors around immobiliser and lock/dashboard.

I lifted the tank and poked the connectors around immobiliser (under seat) and just in case, shook the cables under dashboard, making sure that everything was firmly in place.

Started like a charm.

Theory that I have is, that it is possible, that when I was charging battery, when I removed the tank, that somehow I pulled some wires of of their place.

Good day

Don't you hate that crap?

Glad you fixed it for now, hope it doesn't come back to haunt you!

Excellent and welcome to the forum! :welcome:


Yep, if you tilt the tank ALL THE BACK, its very easy to unplug the fuel pump.

I use a thick Home Depo painting mixing stick (its pretty thick, about 1.5" wide) to support the tank. Plenty of room to work under the tank and the wires aren't pulled taught.

:welcome: to this great forum!

Glad you got your bike started! I would still check your plugs to make sure you've solved the problem so that you won't get stranded away from home.

Hi,

Thanks for all info. I have the same problem with the error and engine doesn't start. I shook cables under the fuel tank and around dashboard, doesn't help..

I had this problem before, it was enough to touch cables around ignition, and error was disappearing. Now to shook the cables around ignition doesn't help and I believe it is some foully cable.

Maybe somebody know how to find that faulty cable ??

Thanks..

What EXACTLY is the bike doing/not doing when you turn on the key?

Does it spin over when the starter button is pushed? Just NOT FIRE?

Are you getting the fuel pump to prime?

Have you checked the voltage at the battery? Should be at least 12.8 sitting..


I'm assuming you have an immobilizer on the bike correct?

You may have a bad cable/harness. It could be where the wire is soldered to the ignition switch. It could be the wire is broken in the harness by the steering.
Please do give more information on the symptoms.

Hello all, I still desperately need all your help and experience.
As per my videos on Deano's Garage ( see Deano's Garage FZ6 project on YouTube)
I am loosing the battle and having to wave the white flag. I have tried everything in my power, tested all things eith multi meter, by way of sensors, leads, coils, caps. Spark plugs changed. I even replaced the throttle bodies. The ECU has been changed as has the wires from old loom, now reconnected to new plug ( having soldered every wire to the old loom)
I am reaching out in desperation, my bike is too nice to scrap for parts, and I do not want to sell it .
The Hi temp in display must be key to the symptoms and remedy, as no matter what I do, this has never changed, unless when trying to start, it has at times changed to low, but when I try again it shows Hi temp and no diagnostics are possible.
Please please, Help

What year bike (S1 or S2) and what exactly is the issue?

Do you have an immobilizer?

Does the Error light come on when you turn the ignition key the the ON position or when engaging the starter?

The indicator showing a HI temp at all times, and the bike unable to go through the start sequence, is usually a problem with the Immobilizer.

It sounds like you had to adapt a harness connector to an ECU that was not meant for it? What was the original bike and which ECU did you install?
