Unless you have a particular symptom or a 'service engine soon' light on I would go buy the following maintenance schedule:
1. Change fuel filter EVERY 10,000 miles.
2. Check air filter at the same time. (held up to a light, you should easily see the light through it).
3. Replace spark plugs EVERY 15,000 miles and plug wires (cap & rotor if so equipped) every 30,000.
4. Don't forget tire pressure - this can have a drastic impact on MPG. Many 'newer' tires require a maximum 44 psi, yet many of us still go by the 35 psi standard of old never looking on the tire. All tires are clearly marked as to maximum psi and remember the average tire gains 1psi of pressure for every 10 degrees.
Hope this helps.

take a test light and make sure you have power to the injectors. then put the test light to the positive side of the battery and check for injector pulse from the ECM by trying to start the vehicle and see if the light flashes.
