Hi FIRST DONT USE EASY START OR YOU WILL NEED IT FOREVER
I had this sort of problem on my horsebox
D reg 0813
On these engines next to the thermostat there is a single wire for the temperature sender
And next to that two wires connected to another little sender unit this is the cold start sensor it has a supply to one side and if cold power runs through and onto a solenoid on side of injector pump...excess fuel for cold start
Check wiring on it or you can just join these two wires together so it just uses excess fuel every start
This will not cause any problems unlike
THE DREADED EASY START😞😞😞
Hope this helps Craig...
