Not quite sure what you're getting at here - I agree, no noise from pump is no bad sign. You can't hear mine running at all. I was suggesting changing a very cheap, even with second hand, relay purely as it is so cheap and easy. Not suggesting changing the pump, I am very much against just swapping all bits on car but you NEED to know if the car's holding fuel pressure with a fault like this. Then systamatically move on to next item to check. Idea of allowing fuel (if it's working) to spray all over the engine is not for me!
