Hi Chris all the best for the New Year - I’m not familiar with Zetec 1800 but am with my cars below.
On both I can hear the pump running for a couple of seconds after turning the ignition on, I am as deaf as it gets to give you an idea.
If you locate the fuel injection rail on the engine there will be a connection you can slacken to see if fuel is getting to the unit. Be extremely careful here though incase the thing starts up on you and you end up in a bad position.
Good luck
