Thanks for the responses. Unfortunately, I'm not going to be able to do anything with the information for a few days or so. Our house was broken into yesterday while I was at work. The culprits made off with both sets of our car keys in addition to a selection of cameras, cash and electronics.
I assume that they plan to come back for the car. They won't have a lot of luck in driving it away!
a quick check to determine if it is getting an electrical supply and operating at all is to stand outside the car on the driver's side in your case, with it being a right hand drive, and switch on the ignition. You should then hear the pump running for half a minute before it switches off.
It's almost certainly not operating. I am now trying to determine whether it is the pump itself that is at fault or whether there is a problem with the electrics. The main problems are the poor access to the wiring and my ignorance - for example, I'm not clear what role the fuel cut-off might play in this.
these do have a history of failing on 150.000km +/-
It has done 170000 miles!
Cheers,
Sean
