More info will help...i.e. how long has it been since she's driven the car and why did she stop? Carbs or FI? How long has the gas been in the tank and sitting? and any other info you can add, along with pictures of the mechanicals if you're not familiar with the car.
It might be as simple as cleaning out the fuel system - old gas is gummy - or bad electrical grounds - they're old and rusty in many cases.
You might be able to do the simple stuff with guidance from us, with a little more info.
You're a champ for helping her out, too.
