T100 Starting Issue After 4 Years Storage

Battery
I know you say you’ve done it but it MUST have at least 12.6 volts otherwise the ECU just won’t let it start

 

Blocked injectors?
If its getting the fuel pump to prime (and get pressure) then I suppose its that as there’s no smell of fuel.
If was no spark, then it'd probably smell of fuel i suppose at the exhaust end.
Put a smidge of petrol in the bores and try to start it?

 

You said the electrics all work, but have you taken out the plugs and checked for a spark?

 

Have you checked the air filter in case it’s been turned into a nest when it was stored

 

Blocked injectors from old fuel varnish is my guess. The injector actuator is a solenoid powered up by the ECU. I would try carb cleaner via the fuel line at the throttle body (plugs out) and crank the engine to open the solenoids.

 

I'd go along with @Callumity, but a couple of weird Triumph things I've come across- have you tried starting with side stand up? My mate's Trident spun very strongly but refused to fire. Side stand up, fired first prod. go figure! And check your headlamp-on some models like my Speed Triple bike won't start with headlamp out. Check bulb and fuse. To be fair I don't think it will spin on the starter mind but I can't remember. Good luck anyhow

 

I am going out on a limb here...

Did you charge up the new battery before putting in the bike? A lot of "new battery" are not charged up at all.

Even if you have jumper connected, it might not have enough juice right away to initiate a start...

 

Is it in neutral?

 

Good stuff mate
