Not your usual Gen 3 starting issue

[Flows]

Ok I did two things since last night.
1 Drained most of the fuel (maybe too much) just enough to get to the station and fill up with fresh 98 for the new tune
2 Flashed the SLR tune
Now it wont start, turns over just fine (has a Lithium battery) but it sounds like the fuel pump is not priming.
Flashed back to the original - no joy.
No error codes.
Put some more fuel in
Still no joy. (and there goes my track day :/ )

Any ideas on what I could try / look at next?

Is the country code correct in the flash?
Do you have an ignition immobilizer?

Thanks 6, hadn't even thought of that, do you know how I would check those?

I'm not familiar with Woolrich, I use Ecu Editor, which has the option to switch between North America, Europe, and Japan, but Woolrich should have that as well.
We don't have ignition immobilizers in the U.S, but the Euro bikes with them have a small red light light next to the ignition key cylinder, if yours has one.
I ask about the Country Code as years ago I flashed dozens of Gen2's, along with some Gsxrs and a few B-kings.
At that time the Busa and B-king settings defaulted to the U.S, and you had to change the country code if need be.
I flashed a Gsxr750('09 I think, I still have the ecu), and then heard a pop, and the bike would not start.
After checking a few things, I realized that the Gsxr page defaulted to Europe, not the U.S, so I had flashed the ecu as the wrong country code, and the Euro bike has the ignition immobilizer.
I flashed it back to the U.S, but no change.
After much more trouble-shooting I bought another ecu...and it fired right up.
What's really strange is that he put his 'bad' ecu into his friend's same year Gsxr750...and it fired right up!
The second 750 had no immobilizer either.
It makes no sense, and may not be at related to your problem, but just something to consider.
Can you try that ecu in another Busa, or a different ecu into yours?

Great info mate, Frank (SLR) is saying it should be an easy fix, something to do with the encryption. Though not sure why it won't start when I flash back to the original.. Will update once I have new mod file. Looks like we get EU bikes here. It has the immobilizer and had EVAP.

Turned out to be as you thought @sixpack577 mismatch with the region encryption. Also a word of warning, you need to do a RESET and re ID the bike. If you just take use an updated Mod file the handheld will have the wrong original file on it so the tune will work but the original wont.

All sorted now, Frank does jump to conclusions, especially about how the customer is always wrong, bit like a 90s IT guy and rather tiresome but with some cool heads we got there in the end.
Take always;

1. If you have an EU bike with an immobilizer it has different firmware so if going the SLR way worth letting him know you have the little red LED on the key cylinder, he can see this from the .fpf ID file but best to provide a reminder so that you don't have to waste half a day dealing with your bike not starting. If you do hit the immobilizer issue while using a DimSport handheld a full RESET is required and re-ID else you may well end up with a second Mod file sent to you that works but an original that doesn't.
2. Non start issues can drain the battery so even with a lithium and a high end charger it is still worth waiting until the battery is fully charged before trying to flash as I managed to get a Code [0x3102] error after trying to flash away from a non starting original. This was resolved by repeating the flash after the the battery fully charged.

Right on, glad you got it sorted out

Right so put it on the Dyno and got less power with the tune.. Better start another thread. ://
