Hi Andrew,

I will try to help you, but how would you feel if your doctor said the following to you;

>>> As far as CR goes its still new to me and I'm feeling my way.<<<

Replace to word CR with lung cancer.

We all have to start somewhere, and it should be in a training session where we can "feel our way" until the cows come home.

The two fault codes you have refer to both the low and high circuits, in my view you need to prove the low pressure supply circuit first.

What is the engine code?

What pressure have you got in the supply line?

How are you testing it?

What pressure have you got in the return line?
