I have a 1996 Mazda 626 (4-cylinder, automatic transmission) that quit running at a red light and will not restart. The engine turns over but will not start. I took it to a mechanic, who told me it needs a new computer and that replacing it would cost more than the value of the car. Is this true? About what would the parts + labor cost?
