My wife stopped to buy gas today. Afterward the car wouldn't start back, it cranks good and had great fire from the plugs. After some troubleshooting I really think it is the fuel pump or f.p. relay. CAn anyone please tell me where the relay is located. In my experience with autos fuel pumps can but usually dont just die at once, also is the fuel filter in the tank or on the rails inline with the fuel line? Please help.
