Hello to all,
im from long island new york
this is my first triumph (06 sprint st 1050 with about 7k miles)
bought it not running, previous owner said that mice got around the wiring. specially around the MAS sensor and Barometer by the air filter. but he said he fixed it.
bike cranks but no start.
the bike only starts with started fluid for a sec and then shuts off. (at least i know a have a spark and compression)
thought i was a fuel issue so i bought a new fuel pump and battery. but still the problem persists.
is there something that prevents fuel from coming out of the injectors ?
It is such a beautiful bike and i cant wait to ride it. So please members i need your help. thank you!
i could post pictures or a video if needed, thanks !

I would probably start by checking the fuses and inspecting the repaired wiring to confirm that the repair is good. Can you hear your new fuel pump priming when you turn on the ignition? Have you checked the airbox and filter for mice nests? Might be worth inspecting the rest of the wiring and rubber vacuum pipes to confirm that they are all intact and connected. Is the small bore rubber tube connected to the underside of the MAP sensor which is attached to the airbox?
