on the passenger side fuel rail is a test port . hook up a pressure guage you need 53psi to 62 psi fuel pressure . key on engine off..this is the step one with this ..next on the driver side is the fuel regulator. it has a vacuum line to it . so on the fuel supply pipe look for this round object with the small rubber vac line . remove this from the regulator and see if fuel is in it . if so replace it..
replace the fuel filter . when you replaced the fuel pump what pump did they sell you airtex ? if so its n/g..delphi pumps have a better result..
installing the fuel pump can be tricky . some do not install the pickup tube correctly ..with many miles on engine replace the fuel pump relay also.make sure the grounds and pump connections are good ..
