Yay! Had the coils the wrongs way around! Wouldn't have thought about that if it were not for your prompt. Thanks a mill!!!!

Nice THANKYOU! Will have a look at what you suggest tomorrow.

Heh, thanks for your interest :). p38 2001 4.0 HSE. It had a meltdown and showed the 35mph hard fault, had to drive 40 miles on bump stops. First test showed the pump not working so swapped that out. While I was at it took the valve block apart and replaced the seals as it was slowly sagging...

Tried to fix eas - Failed! :(
