Any time a fuel-injected car can’t get fuel from the tank to the engine, the number one suspect is the electric fuel pump. These are often located inside the fuel tank and have a finite lifespan. And when they stop, they just stop. That’s it; no warning and only a new pump will get you going again.

However, it’s also worth checking that you don’t have a blocked fuel filter or a kinked fuel line or something equally random that is stopping the fuel getting to the engine. Nine times out of ten, however, the fuel pump will be the culprit.

From your description is appears that it could be repaired, but without actually seeing it I couldn't say how much it might cost. There are websites you can use to get a quote on-line and I'd suggest you do that. Google "bumper repairs".

It sounds like a lovely old car, one I'm sure a Mazda enthusiast would be happy to have. You could Google Mazda car clubs on the internet to find one in New South Wales, or alternatively you could refer to one of the classic car magazines, such as Just Cars, where you will find a listing of cars clubs.
