Thruxton Thruxton 900 Efi Non-starter

JungleGus · Dec 12, 2017

So, strange issue today - I installed the New Rage Cycles tail tidy (I need to cut the old tail tidy plate to fit, but that's a different story) yesterday - popped out to the shop to get some fuses (i.e. the bike was running) and parked her up.

Today, I had to move the bike across the street while they cut down the trees outside my house - no issue there. Come later in the day, I started the bike up, departed - then got around 50m before the bike died and I had to roll it home. The engine is turning over, I can smell fuel - but there's no ignition. I am guessing there is something wrong with the spark.

Any ideas on where I start to diagnose this? I find it very odd that it ran briefly before dying.

Cheers,
Gus

Have you run a plug out, earthed it to the head (rag over plughole for safety) crank engine and checked for a spark?
If no spark you need to eliminate the ignition coil and its power supply, then the crank position sensor (another coil) and the ECU plus all the connections. Got a multimeter?
Just verify the spark status and we can take it from there.....

And rule out a fuelling problem like a MAP sensor that could cause flooding.....unlikely once started but if it was cold....
