Question about Dodge Cars & Trucks
Before doing ANYTHING, it is VERY IMPORTANT that you depressurize the fuel system, and be sure the engine is COLD COLD COLD before removing any lines.
The fuel pressure regulator should have one vacuum line and three fuel lines connected to it. (Some have an electrical connector instead of the vacuum line, but same idea.)
AFTER DEPRESSURIZING THE SYSTEM, with engine COLD, carefully disconnect the vacuum line (or electrical connector), then SLOWLY loosten and remove all three fuel lines, noting how they are connected. Replace all grommets & gaskets with new, then Install the fuel lines to the new regulator, EXACTLY as they were on the original, tightening the fittings to torque specifications provided for your vehicle and engine. Reconnect the vacuum (or electrical) connection, then repressurize the fuel system WITHOUT STARTING THE VEHICLE. With the ignition ON, watch for any sign of leaks. If there are ANY signs of leaks, stop them before starting the vehicle. DO NOT START THE VEHICLE IF THERE ARE ANY LEAKS, AS THERE IS A DANGER OF STARTING AN ENGINE FIRE.
Check for proper fuel rail pressure, and be certain to re-check your work within 100 miles to assure that there are NO LEAKS.
If you are unfamiliar with depressurizing or repressurizing a fuel injection system, PLEASE REFER THE WORK TO A QUALIFIED TECHNICIAN..

I doubt the regulator is bad, the fuel pressure regulator is after the injectors in the return stream to the tank, more likely it is the fuel pump.

SOURCE: fuel pressure regulator
Have you checked the fuel pressure? If it is high and fuel is not returning, the regulator is bad. If it is low and fuel is not returning, the pump is bad.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls

Should be attached to the fuel rail. The fuel rail connects all of the fuel injectors. The regulator will have a vacuum line on it.
