Hello, ive been having a bit of bother with cold starts recently. The car was off the road for 3 weeks and the garage it was in at eventually ended up replacing the metering head after going through a lot of other possibilities. Its been running fine the last week up until the last two mornings. Its now back to struggling to start again. Even when i turn it over and floor it there is nothing going through it until it eventually chugs splutters catches a few revs and then i have to give it a good few revs until it gets going. Sometimes i have to floor it again before i get anything back. Any suggestions? Also the car has been using a lot of coolant/water of late, i have to refill every week. Help!
