My RR wont start, every time i try and start it it turns over and fires but dies as soon as i let go of the key... The coolant reservoir is building up alot of pressure with every attempt to start, if i leave the cap loose it pours out coolant! any ideas why its building up so much pressure without even starting? could this be whats stopping it form running? I have noticed there is a slight leak from the passengers side off the block in the middle... any help is much appreciated!
