SOURCE: Fuel pressure regulator
Very easy if you have the new one just look at how it is mounted, most times just a couple of retainning screws and it comes right out, bleed the fuel system of pressure before you take it out or put a rag over it, there will be about 40 PSI in the fuel rail.

Engine coolant temp sensor, If you pull it you will be able to see if it is cracked.. I don't know why but the original sensors they designed the ceramic tips crack around the tip of the head.. It will make the car nearly impossible to start smoke when cranking the engine, and idle really rough racey infact. 15 dollars or so let me know if that worked for you

If its BLACK smoke it's unburned fuel. If it has carb, the carb float is too high or sunk. If it has fuel injection it's a stuck (open) fuel injector.

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

SOURCE: cant hold pressure in fuel rail
i'm assuming you disconnected the fuel line and placed the line in a container to catch the fuel when observing the flow.
it might sound strange but i think there might be a leak in the tank coming from the fuel pump assembly. it's possible a tube or hose is broken on the assembly and the pump is just pumping the gas back into the tank.
there's flow because there is no pressure building up with the line disconnectedand the gas flows. when connected, pressure builds and blows out the break in the tube or hose.
