Daytona T595 Won't Start

Hi all, problems with my beloved t595. Its a 1999 model that has been off road about 18 months whilst I sorted the cosmetics and running gear. Can't get bike to start now, good battery with plenty cranking power. I hear the fuel pump prime when I switch ignition on but there is no spark and plugs are dry so it looks like no fuel as well. I have checked the stand, clutch, neutral and kill switches plus all fuses, all are good. Ran a 12v supply to fuel tank and fuel pump runs ok. Thinking now its an ECU issue unless there is something else I'm missing? Has anyone experienced a similar problem and managed to sort? Better weather on its way and really keen to my bike sorted for the new season.

@DelboyP Welcome to the family. Yes its not nice when you have a sick bike. Check all the wiring and earths plus the ignition switch. Have you tried all three leads for spark. I do hope you get it sorted soon so you can get out there on it. Have you got a reader to check the system.

From your symptoms it does sound a bit ECU-ish.
However, give the wiring around the headstock a thorough check, it was common for the 595i's around that year to develop wiring breaks due to the loom being too tight from lock to lock.

Tanks for feedback. I've checked all plugs and stick coils, no spark any cylinder. Will go have a look at harness around loom though its looking like I'll need to bite the bullet and find another ECU to try. Happy days...
