The fuel pressure regulator does just that. It maintains the proper fuel pressure although it's pretty rare for one to cause a "no start". I've never seen that happen. It is much more common for a bad fuel pump. You need to use a fuel pressure gauge to determine what the pressure is. This truck requires a MINIMUM of 55PSI to run.
