You don't have to use a machine to check for some codes. You turn the key, just till the dash lights come on. Cycle the on--off, on--off, on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
As far as the fuel filter, that is why I asked, how long since a tune-up? Use a gauge and check fuel pressure.
