Triumph 955i Rs Sprint Won't Start

When it started when you changed the plugs that suggested it got something it hasnt been getting ( air?)

I've had a look at the "Sprint won't start" thread but can't see anything that matches my problem. My 2002 Sprint 955i won't turn over on the starter button but I can start it by putting a screwdriver across the terminals of the starter solenoid. I've been told this means the starter motor is ok.
The wiring diagram in the Haynes manual shows that horn and rear light relay are on the same circuit. The horn isn't working but the rear light is. Do you know what the problem might be

 

Have you checked your fuses.switch them out if you can, they can look fine and still not work.

 

@ Shawn Does it try and start if you crack open the throttle slightly?

 

I will try that. I replaced the starter solenoid but that didn't fix it
