Don't forget to change your fuel filter too. The filter also contains the fuel pressure regulator. Clogged filters can work the fuel pump to the point of failure. If that doesn't work, test for about 55 psi at the fuel injector rail. There is a Schrader valve there to hook up a gauge. Next, scan for fault codes but I think it is just a fuel problem.
