I know they said the fuel pressure isn’t correct, could it be something else leading to the fuel pump failing but not the part itself being faulty? Thanks for the help
Yes, you take the fuel line off the inlet and outlets sides, take out the two half inch bolts that hold it in place, look and see if the diaphragm is torn or cracked, hold the pump body with one hand and push on the plunger with the palm of your other hand. If it goes Uuugaa - Uuugaa the pump is usually OK. If not, it's time to make a trip to the junk yard (unless you have a spare from the junkyard in your trunk).

Oooooo - SHIT - wrong forum - strike those instructions me!
