Coolant is ok- was replaced a couple of weeks ago.
I've got power to the starter and it's cranking over a good one, just not firing. Still not done anything to investigate further- will have a ride over to it tomorrow and check for fuel and spark.
After a few minutes cranking the engine bay did smell of petrol so assume we flooded it- assume its got fuel and no spark.
Hope that's the case, if its got fuel and spark then its serious!
