Got home from work this evening and tried the XT. Key in, ignition on, no errors but no EFI priming either (you know the noise you get as the fuel pump pressurises).
Ignition on and off a few times and eventually EFI primes. Press starter and nothing.
Ignition off and on, no EFI, off and on, got EFI, press starter, got a tick!!! We have progress!!!
Repeated this several times and we have a starter.
Long story short, after several minutes I manged to get the bike to start whereupon it ran for half a minute then stopped. Repeated the same steps (fewer times) and got it started again. This time it ran for five minutes before I switched it off. We have takeoff!!!
I have managed to get tomorrow morning off work and will take the tank off and check the connectors underneath. Will also run the diagnostics and check the sensors.
For all the advice received so far, much appreciated and
Tonight I have reached the
stage until tomorrow...
