urS6 wont start

[goodall]

The S6 has lay up for the last couple months as the mot had expired, i had been starting here every 2 or 3 weeks, however over Xmas the battery went dead cause the cold and due to laziness couldn't be bothered running the extension cord out for the start charger, but today got round getting start charger to her she wouldn't start, turned over fine and quickly but didnt fire on anything. Put gallon petrol in her as light was on and remember the pump was starting catch air when i moved her last, loosened one fuel lines make sure was fuel was alright, which was confirmed by a spray from the union as loosened it. So as last attempt tried quick bit petrol into the air intake duct, and she kicked on 2 cylinders with and the other 3 will slightly picking up.
Haven't a clue to why wont start so guessing something fuel injected related but not sure, anyone ever had similar issues?

Have you check if its sparking?

Also could it be the hall sensor or Motor/ECU fuze?

Maybe you got some damp somewhere and that created an arc and has blown a fuse?

Good luck.

I'd check the hall sensor first alright - they dont like temp extremes when they go bad.

Also worth a general check of all electrical plugs in case something has had water ingress or something while sitting laid up.

How would check the hall sensor? Is case replace with a known good one or what?
May do a fuse and plug check tomorrow in day light

LED across pin 2 and 0V at the hal sensor - should blink every other crank rotation.

Tried her this evening, started 1st turn! So what ever was might been temp or moisture related since been warmer last two days and brezzey. How I'm still going need to find the root cause at some point...
