Default Still no start

Thanks for your help so far guys,
I must admit it does seem like cam timing,
Tooth 7 lines up with sensor, should I line the front of the tooth with the centre of the sensor to be precise?

Does this look correct I make it 14.5 pins between marks,
Lobes pointing 10 and 2 o'clock,
Could the chain be stretched? It has a manual tensioner with about 10mm of travel left.
The spark plug only looks wet when starting with wide open throttle?

Cranking voltage 11 volts
Cranking about 300 rpm according to guzzidiag
All parameters reading, all seems correct compared to 1 on the forum.
Cleaned every connector today in the loom,
Will go and check Ecu pins.
Is it possible for the cam chain gear on the crank to slip?
Thanks again

I've usually aligned center of the tooth with center of pickup coil. But center and front of the tooth is so minimal change so i don't believe that could change anything.
Timing on your cams seems ok to me...
Have you tried new spark plug?
Throwing out ideas....
Usually when my FSE wount start normally then it will start with wide open throttle. BUt yeah try maybe new spark plug? :/

Check through the spark plug hole if the piston is in tdc

She's up and running!!! never would of found it without guzzidiag, ignition tested fine when plug wasn't in the head, but when I screwed it in the head with the coil pack on it threw up a fault, after alot of head scratching I found the steel outer tube on the coil pack had slipped down, pushed it back up siliconed in place, jobs a goodun, cheers
