Thank you for the advice. No there haven't been any trouble codes showing up yet. Where do I find a fuel pressure gauge?

If your going to work on your own vehicle, a fuel pressure gage is a tool you need. The autostore sells them. Some national brand autostores used to loan out a fuel pressure gage.
