I couldn't have said it any better. :

Thank you. The gray harness you are referring to sounds like the headlight harness. I checked all of them on the left again and they are all good. if the ground was bad in that harness the bank angle sensor would not send a ground signal to the engine stop relay causing the engine stop relay to remain OPEN. If the engine stop relay DOES NOT close, no power is sent to the ECU, injectors, ignition coils, fuel pump, exhaust air inject solenoid valve, (and the PC solenoid valve & O2 sensor for California bikes). The bike will obviously not run if this is the case.

As far as what the manual says to check, I've checked it all. I cannot say that every wire on the bike is good because I don't have another bike to compare values of certain wires to :/. The manual doesn't cover everything unfortunately. As far as the ECM goes, I bought one from a guy on here but it did not solve my problem. Mnguyen84 said he would test my ECMs for me THANKYOU!!! So if the new ignition base (part with zener diode anti theft system) does not fix my problem, I will be sending him my ECMs.

 

So, what's the ETA on your new ignition base ? At least it's not too expensive at about $35.

 

I'm hoping it arrives Friday sometime but I'm not getting my hopes up :/. It cost me 48!! I have a feeling it won't fix my problem since I get 8.7v on the pink wire, but at least I can rule it out if it doesn't fix it!

 

It would be nice if you could find some documentation somewhere that says specifically what that voltage should be and within what tollerance. 8.7v is really close to 9, but still you don't know what the expectations are from Honda. Keep us posted and here's crossing our fingers for you.

 

Yea I know! I really wish I could speak to Honda's bike engineering dept!!

Anyway, I tried the new base contactand as I suspected...still no go ugh!!!

 

Clean your kick stand sensor i played w mine and ti was the magic bullet had the same prob as you do i cleaned the contacts and resoldered a wire give it a try

 

Thank you for the suggestion!!

I've tested my kickstand switch and it tested good. I tested the switch for continuity across the switches leads (at the plug) AND I also started the bike (with the fuel cut relay jumpered), kickstand in the up position, pulled the clutch in, put the bike in gear, and then i put the kickstand down while the bike was still in gear. The bike shut off so I know the kickstand is doing its job.

 

Had this issue. Dealership diagnosed it and said ecu went bad.

 

Yea I think that is what my problem is, but I won't know till I test it on another F4i. I might be buying another F4i soon; If I do I will have an identical bike to compare everything to.

First I will put my current ECM in the new bike to see if the bike will start with it in. If it doesnt then I know its the ECM. If the bike starts I will then read every single voltage going in/out of the ECM and compare it to the non running bike. Whatever differs I will then investigate.

I really think it is the ECM though, so I will find that out pretty quickly.

I will keep this thread updated whenever I take the next step.

Thank you all!

Just an update. Deal on bike fell through. So for now I jumped the fuel relay and it runs fine.

Still looking for sombody that has an F4I to test my ECM. If anybody wants to help a fellow rider I will cover you for your time. No problem driving to your location.

Still looking for another ECM but am a little bit scared of getting one used due to the fact that the last one I bought is not 100%. It does not send the ground signal to the relay so I have to keep it jumped out. Without another F4I I can't test all wire values to ensure both ECM'S are bad. Everything points in that direction though .

Will keep you guys updated if anything changes.
