what is the problem with the car? If the car is cranking over but will not fire the spark plugs or run the fuel pump then your problem is with the main relay. The main relay is located under the instrument panel, probably under the left side of the dash to the left of the steering wheel. That relay has a circuit board in it that cracks and opens the circuit for the ignition and fuel pump circuits. So if the engine is turning over but you don't have spark or fuel, that's your problem. Its very common on that year and model.if the engine is not turning over and you've changed the starter, you may have a problem with a neutral safety switch. On a manual car that prevents the car from starting unless the clutch is pushed in. On an automatic, its the switch that must be pushed in by the gearshift lever when the car is put in Park. If the neutral safety switch is open circuited, the starter won't turn when you turn the key to the start positon.Lastly, I don't know if you have power to the starter or not. There is usually a fusible link in the circuit that could melt if the starter was pulling too much current. A fusible link would open circuit the starter and it would not turn when you turn the igniton key ON.additionally, the battery may not have enough juice to turn the engine over or the cables may be loose or corroded.There are other possibilities depending on whether the engine turns over or not. It would help if you could give us more information on what the car is or isn't doing.hope that helps
