Just clicking won't start

[crazy]

Battery was knackered so bought another, got it to start but keeps dieing and engine light is on so I'm thinking its a fuel issue now,
A m8 got back from Holliday he's got computer to plug in to it but can't get it until Tuesday when work re opens
But at least I got it off busy road and onto drive out of traffic
Thanks for all replies from everyone been a great help

Lift up the back seat and listen for the fuel pump,

Early ones are suffering with pump failures now.
