Thanks for that. I’ve changed the relay and it clicks well when the ignition key is turned.
But there’s no sound from the pump priming. It’s an intermittent fault. Sometimes just leaving the car overnight in my garage and it will start as normal the next day although I’ve done nothing to it.
It’s rather annoying as it makes the car unreliable.
Sounds like it's just a faulty connection somewhere, try running a temp feed from the battery (& the earth too as these are notoriously dodgy) and see if you get the pump running reliably first
