Fuel pump

The first thing that should happen when you key the vehicle up is a two second prime, you should hear a click in the under hood B.E.C. (bussed electrical center) and then you will hear your fuel pump run for two seconds. The fuel pumps are quite noisy so you shouldn't have any problem hearing it, if you do hear the prime, then I would do a pressure check. and the last thing I would check is to see if the pump you had replaced was installed properly and to see if the fuel hoses in the fuel pump module are not damaged, if they are then you will need a new module and those ain't cheap! If you don't hear the prime I would check the circuits in the under hood B.E.C. there is a menu on the cover that will tell you what fuse and relay does what job. as for replacing the fuel filter again, it's always a good idea to replace filters annually but unless you have had real crappy gas I don't think this would cause your problem.
