IT SOUNDS as if the engine is running too rich, which could be caused by a faulty oxygen sensor in the exhaust. It's there to monitor the air-fuel mixture and send signals back to the engine-management computer. If it's faulty it could be sending the wrong message.
The first thing to do is drive the car yourself and see if there’s a pattern to what’s happening. Until then, you have even less idea of what’s going on and a diagnosis is all but impossible at that point. You might find that the car is cutting out after a period of driving (maybe caused by a dirty fuel filter) or when the engine reaches a certain temperature (possibly a sick crank angle sensor).
I’d also recommend an electronic scan to see if any fault codes show up. These codes can be very specific and will often lead you straight to the root of the problem.
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.
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".
THE price is average for that model and year, but you'll have to pay for registration as well anything needed to make it roadworthy. Add the body damage and it's starting to look less like a bargain. The low mileage is attractive, but find out how much you will have to spend to get it back on the road with a full year of rego. If it's more than $1000, think twice about it.
IT'S at the high end of what I would expect, but it's hard to provide a reason without knowing if you live in a hilly area, if you keep tyre pressures up to the correct level, if the wheel alignment is within spec, and if the engine is in good condition.
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.
