98 lumina wont start

it wont start i replaced fuel pump and relay for fuel pump and checked all fusses and relay's cant get any fuel presser at all all most a year ago please help im go in crazy really need the car

Sat for a year? got power to the relay? Pump properly grounded thru the harness?

Checked the fuel pump fuze? Did you replace just the pump or did you also replace the sending unit with the updated version? Many of the sending units of that vintage had problems with shorts in the sending unit due to a flaw in the manufacturing of them. This applied to several GM models.
