    Have you checked your fuel pressure. You should have about 45 psi at the fuel rail. You might have a weak fuel pump, bad fuel pressure regulator or clogged fuel filter. The simplest first step is to change the fuel filter and then go to the FPR and see if the diaphragm is leaking. You can pull the FPR's vacuum line and see if there is fuel in it. If so replace the FPR.
