Fuel Presure Fault

[pro_steve]

I would clean the fuel pressure regulator again, if you've used crap fuel you'll hav3e dirt in the system and the regulator will get problems frequently. Make sure the seals are good too.

I would also recommend running an injector leak off test. Bad fuel will wreck the injectors very quickly. If the leak off values are all different then it would indicate you need a new set of injectors too.

Try this and update us and we can advise further.
