The first thing you should try is replacing the fuel pump relay. It is very easy to do just open the fuse box under the enging and look on the bottom of the lid and find the fuse. I believe it is 18 and just replace it. They are like 13 buck at auto parts store. If that does not work try replacing the map sensor. it is located right behind the intake manifold. it is just 2 bolts but they are a pain to get out but it just takes a little time. If that does not work replace the fuel pump. Also i would replace fuel filter first because it probably needs done anyway and it is cheap and could be the problem. hope this helps
