if you're getting no pressure then remove the vacuum hose from the regulator on the fuel rain and check if there is no gas escaping from there
if that's good then remove the plastic cover that's under the car in front of the rear tire on the passenger side and that's where the fuel pumps and the filter is.
check if both pump are priming/running
