Hello. My name is XXXXX XXXXX I will be assisting you today.

markthebooler :

Does the smoke reduce as the engine warms up?

Customer:

no the smoke does not reduce

markthebooler :

I would first check the cylinder head temperature sensor as it maybe telling the engine ecu the engine is cold when it isn't and overfuelling.


 

Customer:

i will check engine temp sensor and if it checks out ok is there any other suggestions on this problem'

markthebooler :

Water in the fuel filter or contaminated fuel. Has it recently been filled, possibly with petrol?

Customer:

the fuel filter and air filter have been changed and has not had any petrol put in by mistake

markthebooler :

The next thing would be to check the cylinder compressions as that is about all that is left.

Customer:

could the hp pump be at fault

markthebooler :

Possibly, but normally it wouldn't cause white smoke.
