I'm not sure what filters you are refering to. Has the engine light come on? Also, have you checked the fuel pump pressure? It could be getting low due to a weak pump.
Here is a How To video:

Let me know what you find. Also, if you need a gauge, many parts stores will rent them. If you can't find one, they sell them here at the test equipment store.
Let me know what you find.
