Hello Everyone!

I'm currently working on a 2007 Street Triple 675 to put it on track as soon as possible. It was a frontally accidented bike and after the replacement of the dash, triple tree, forks, clutch cover, and the taking off all unnecessary stuff it's ready to run.
However... After putting all together and turning the key, the dash (which comes from an other accidented same year bike) lights up, seems fine but the fuel pump doesn't want to prime and nothing happens while pressing the start button either. I checked the 2 connectors going to the fuel pump and there's no voltage regarding any timeframe.

Can it be an issue caused by the "foreign" dash? If so, can it be detected and fixed through OBD in the ECU?
Can it be a result of the accident ("tip sensor" or "fall detection switch", whatever it's called - I don't even know if a 2007 bike has one or not) and if so, could it be fixed in the ECU?

I would be really happy if someone could at least send me in the good directon, or give some ideas...

Thank you in advance!

On that generation any dash (that looks the same) will work. On the newer generations the dashs are coded to the ecm. The bike does indeed have a tipover sensor.

If the fuel pump does not prime the starter is locked out and bike won't turn over.

Tip over sensor is a small black box mounted at rear of air box. It should have an upward pointing arrow on it.

You can see if it's the problem by unplugging it and jumping the connector.

Problem could also be the clutch safety switch. Unplug it at the lever and jump it to bypass.

Thanks for your answers guys.

After digging into the forum, I considered the clutch switch, gear sensor, lambda sensor, side stand sensor, and all the missing dismounted stuff such as lights. But for me it is not logic not to prime the fuel pump and not turning the starter even if all those. It doesn't make any sens for me not letting the bike start if you have a dead light bulb for example. And at least the pump should prime even if you are not touching the clutch, or on side stand or in gear.

But obviously I'll check out all the stuff yoyu have mentioned, thanks a lot.

I have ordered a bluetooth OBD scanner, I'll try to figure out what's happening in the ECU with all available applications and we will see...

As I recently found out the dash comes from a same year Daytona (which was accidented as well) and not from a Street, maybe that's an issue as well...
And I dismounted the emission control stuff as well... Maybe the ECU is missing its solenoid or I don't know... Hopefully I'll find out with the OBD diagnostic.

Well... This evening I was trying during 1 hour to connect to the ECU with an OBDLink Mx+ and TuneECU on my Samsung S6 tablet... The best I could get out of it: "ECU is not responding...".
I have tried it all possible ways, with and without the Dayto dash being connected, ignition on and off, etc. And at the same time the setup is working nicely on my 2014 Street.

So I don't know but I have even more doubts after this, than before. Now I'm questionning the ECU's and the harness condition as well. If it continues like this, the "cheap track project" will become very expensive.

Any further ideas/ suggestions gentlemen?

Update:
One of my Triumph fan friends brought me a plug to bridge the alarm slot on the harness... With that in place I have the check engine on the dash, and I can connect to the ECU with the OBDLink Mx+. As Far Canal highlighted the ECU is upset about having a Dayto dash... So basically that's one step forward...

Now I have to find a 2007-2010 Street dash I suppose. Any cheap ideas?

Unfortunately I don't have the original dash. It was completely destroyed in the accident as the selling garage said.
Honestly I was hoping for cheaper solutions than those dashes on ebay. But probably I won't have other choice...

Thanks for your help!

Triumph and cheap don't often go together in the same sentence haha.
In all seriousness, they are a 15 year old bike and parts in good condition are becoming few and far between.

I'm not 100% agree, exactly because we're talking about a 15 years old bike, which is pretty simple and shares most its parts with the Dayto, and talking about the first generation most parts remained unchanged. These bikes are pretty cheap used, and plenty of second hand parts are available (at least in France), that's one of the reasons why I chose it to start on the track.

And because of the track usage I don't really care about the dash's condition, probably I wouldn't even think about to put a dash on if this freakin' ECU wouldn't miss it...

Anyways, thank you very much once again. I'll try to find a cheap dash, and we will see. Hopefully its's the last surprise, I'll update you about the resullts afte finding a reasonably priced dash.
