Question

2005 Mercury Mariner 3.0L with code P0194. Will fuel rail pressure case car not to run?

Answer 1

HI thre,

The rail pressure sensor shouldn't cause the car not to run. However, if you have the code because there isn't any fuel pressure the vehicle won't start. So, check the fuel pump and make sure you are getting the proper fuel pressure, if not, then the pump may be bad and the truck won't run
