Fuel pressure low even though I just put in new fuel pump, replaced fuel filter, cap and rotor new plugs. Oil pressure sensor is it reset able when I clear codes, not seeing code for it but what else be. Plan on going after fuel regulator today do not think it is the problem. What else could give low fuel pressure?

Hello my name is Dave.

It sounds like you are on the right track with the pressure regulator. However, a faulty injector can also cause a low fuel pressure issue. Since the engine is not starting what I would recommend is to try starting it, turning the engine for short bursts around five times or so then pull the spark plugs and see if one of them is obviously wet. If you do not find any that are wet then I would move on to the regulator. Hopefully this will help you track down your issue and thank you for using 2CarPros.
