Could definitely be multiple problems. I'd focus on electrical and fuel supply first: maybe it's barely getting enough voltage to run the pump. Don't expect full battery voltage, but 7.5v is too low. ...

Replaced the coil and checked the spark leads again, and the car sounded a lot better for the 5-10 seconds it ran, before dying.
