Hi Dave,

Thanks for your help.

Eventually found the problem after spending a fortune.

It was the DDE power relay having a high resistance contact.

$60 fixed it.

Before it was replaced, I simply removed the relay cap and separated the contactor arm from the body.

Cleaned both surfaces and all works perfectly

As the relay was not making a good electrical contact, it was only providing an intermitant  low voltage supply to most of the engine control systems.

You can measure the voltage between any of the three 20A fuses (located next to the DDE) and ground.

I hop this will help others in the future.

Regards 

Mike W

Where Is this DDE relay located please
