I Ride:
'09 FE450 - won't start - pump/injector seem ok?

Hi all,
Have a '09 FE450 which wont start:

1. Checked spark - seems ok (have not removed plug, just checked on engine casing)
2. Checked fuel pump - pumps fuel OK (have not checked pressure but it primes & pumps when removed from tank)
3. Checked injector (removed & cleaned, can see it spraying into inlet when cranking over)
4. Starter motor cranks over fine
5. All other electrics function fine (lights etc)

Before I take into dealer for further investigation, any other tips? Ie friend thinks could be a bad earth which allows everything to function but no start.

Where/how would I check this?

Bike was going fine then started to splutter & die on a ride. Trailered home, next day started and ran OK for a few seconds then died, now she wont start

Cheers,
N

Did you find out what the problem was, could be a loose battery connection?

Well normally of there is compression,spark ,and the efi has been check ...it should run..(other things could be valve..maybe drooped ''I had it'' but as long as there is compression that's not the case).for what I can think it can be some elettrical like your friend is saying...but there is spark

if it dies on a ride that's a bad thing I really hope you dont find much trubble

I had 2 bikes one pitbike and one ktm(2 stoke) stop staring when I was out and both need engine rebuild

Have it check and let us know what's going on
