No the fuel filter it not hard to change. It is on the inside of the frame on the drivers side it is large round can. As for the engine light what I would do is call around to you local parts stores and see if one does a free a scan and take it there and have them scan it to see if there are any codes. If there is write them down and then have them clear them. Get back to me with what codes there are.
You might need one of these tools to change the fuel filter.
the fuel filter should look like this
