EIS problem? Have you had it scanned for fault codes?

Did you disconnect the battery before working on unbolting the starter motor? There is a 200A fuse in the pre-fuse box. It’s next to the battery, in a plastic unit that has the jump start positive point in it. You might have blown that big fuse, but you would probably have been aware of a spark or crack sound if you have. It’s the same feed as the big wire on the back of the alternator, so thats a good place to check if you have 12v. It should be live all the time

I dont have a scanner and nobody is available to come out to scan it

No the battery was never disconnected

You might have blown that big fuse then. Definitely worth a look

I don’t recommend a job like that without disconnecting the battery. Seriously risky

Another thought has come to me. It might have a clutch switch, so it will only crank with the clutch pedal pressed down, but iirc the switch is at the pedal end, so unlikely you’d have disturbed that. If the fuse proves to be ok maybe look at the pedal next. I’m sure there isn’t anything at the gearbox bellhousing end that detects pedal operation. You’d remember if you disconnected anything electrical, I’m sure

Absolutely - working in the vicinity of the flywheel with a connected battery is lunacy.

Thanks you everyone i think ive sorted it as it seems to be one of the clutch pedal switches staying live
