Your Car should have a self Diagnostic system under the hood, it is a small black box with a lead that plugs into one of six ports on the top of the box and there will be a red led light. You can look up the codes and how to retrieve them in a Chilton Manual or on line.

Check you O2 sensor on catalytic converter, if it is disconnected car will not start or run terrible. Any check engine light on?

Is the airfilter nice and clean? Vacuum hoses are in good shape?There is also two fuel pumps to check, one feederpump in the tank and a booster pump under the car, roughly under the driver seat. Both needs to work.

If you have spark to all plugs and fuel to the fuel rail, it is most likely your fuel pump relay. this also operates the fuel injectors.
