There is a fuel pressure pump, fuel pressure regulator, & a relay, what do u want to check, well anyway first check your fuel pressure using a fuel pressure gauge, if u get 40 lbs pressure then u r good there lower u have a weak pump, if u get 40lbs of pressure but it does not hold that pressure or it drops off real fast then u also have a bad pump , if u get no pressure reading at all then u will need to check electricals for power or blown fuse, post back soon good luck.
