Re: Fuel Pressure Regulator Location
Have you pulled any engine codes? What month in 1994 was your car built?? My fuel filter has fittings so you need a wrench to change it. It's located underneath the car by the left side chassis rail directly below the firewall. It also has metal lines at that point. Do you know how to pull engine codes as you do not need a code reader to do that? The car will spit out the codes by flashing the check engine light.
The fuel system is designed to hold pressure when the car is shut off via the fuel pressure regulator. Somehow, you relieved the pressure when installing the new filter. I have NO idea how that happened. Please check the vacuum hose on the regulator. If it's not getting the vacuum due to a vac leak, it won't run right. It also may be injector problems as the car sat in your humid conditions there. You may have gotten some water into the system & it rusted up. Could explain the burned up fuel pumps.
