Problems - UPDATE.
Just wanted to give you all an update. Well most of the problems of my vehicle seem to have now been resolved. It seems the issue with the vehicle not starting and the speedo was something to do with a cable which had snapped, which connects to the battery (can you tell I am not techy).
The issue with the engine cutting out was a relay and this was sorted by the team at JJB Motors, York! Thanks guys for the help.
Ill keep you posted of any other updates as they happen.
