Hi all, it's definitely not sparking with the side stand up or down.
The bike makes a noise when i turn the key but I'm not sure its the fuel pump!

Easy to check, put your head near the pump and turn the key!
Sorry, couldn’t resist. It should make a whirring noise - that’s the pump

I 'killed' my bike after giving it a wipe down with a cloth, it turned out I managed to disengage the clutch safety switch, it was a tiny metal leaf spring that presses against a micro switch and I dislodged the leaf spring.... I can't recall if it was my 961 or my ThruxtonR... I do recall thinking "what idiot would design such an incredibly exposed switch mechanism" so I'm inclined to believe it was my 961 'cos Triumph wouldn't make such a terrible design, would they!?! Next time i'm out close to the bike I will take a look.

Check the coil and spark plug wire connection under the tank.

Once you are sure the fuel pump is working (pumping up and then shut off at pressure) , and then you are still certain no spark at the plugs while cranking engine over. Then , you are free to remove the fuel tank so you can start to troubleshoot a little better . With the tank off , you can get to the connections of the coil pack etc.. And you can crank over the engine while you are checking for spark. You can always bring it to one of the previous Norton dealers who will still have the ECU cable and software for the OMEX and I am sure they can help you retrieve the sensor data etc..

The battery is showing 12.1volts. Would that be enough to generate a spark?
In the manual it says it should be 12.6 or above to spark?
All fuses are good and in place.

12 volts is enough to provide spark. You stated it cranks over correct?
can you give us a update to all that you have checked so far please.

Yes it's cranking over pretty well.
I've checked the connections from the loom to the tank and all the fuses.
I've spoken to the alarm guy (Datatool) who said the immobiliser wouldn't be preventing it from sparking as it's arming etc all ok.
I called Krazy Horse who said that I've checked everything they would so I'm at a bit of a loss.
I'm not great with electrics so running out of ideas!
Does anyone have a video of the fuel pump priming?

The workshop manual has a trouble shooting section (19) which has a checklist for no spark. The ECU is mentioned twice! If the ECU is the culprit then Krazy horse has the code to interrogate the ECU so you might need to transport to Bury

Check all relays/Fuses are firmly seated and nothing blown.

I know you said electrics are a bit of a mystery ...look at the first vid I posted, are you able to check the pump is operating using the method shown in the vid. If the pump is not working then it removes the search through the electrical system, if the pump is fine then it’s a systematics trawl through relays and wiring.

Not necessarily- if the pump is not working then the ECU will cut the spark to prevent damage. It makes sense, you don’t want a partial detonation with a small amount of fuel in the chamber or a spark into a fuel free chamber. If the bike is turning - trying to start - then it should rule out the alarm as this would cut power completely if working correctly.
