Check the fuel injectors with a noid light. Just a 12 volt bulb with positive and negative leads. Touch them to injector leads and turn engine over and if it lights up injector is okay. It might be clogged, so if I did not mention it a can or 2 of quality fuel system cleaner will do wonders. BG44k is the best but you have to get it at the parts counter of car dealerships and its $20 a bottle. Sea Foam is easier to get and a good second choice. You might experience rough engine performance when you use it as it removes deposits which eventually settle in the oil pan. So, after 2 tanks of gas, each with a bottle, then one tank of gas after that be prepared to change the oil as it will get dirty.
If your fuel filter is that old it is certainly adding to the issue if not causing it. That may fix your problem.
