I've just gotten a tune up [plugs / wires] and still having problems starting it . The check engine light does not come on so I don't have a code and fuel mileage is still down maybe 20 miles to the gallon or less please help

 

have you changed your fuel filter lately? if its clogged you may not be getting enough fuel to start it. if you can, have someone check your fuel pressure to make sure your getting the proper amount. if after you change the filter the problem still persists, i would have the pump checked. could also be a bad ground wire.

 

The models before 06 have a fuel filter to remove? That's interesting. What does it do when attempting to start?
