does DCI mean diesel?
If so, Did you pre-fill the new filter with diesel before you fitted it?
if not it's probably air in the system, you have to crank them a lot to bleed the air back out
Never a good idea to crank diesels for ages, pumps are lubed by the fuel. Hence best to bleed the air out of the system.
I’m aware
