1987 300 wont start

Looking for diagnostic help on my 300 se. it ran fine stopped for lunch wont start now. battery is fully charged smell fuel while trying to start but unsure wheather it is fuel or ingition problem. I hear fuel pump when i first turn key on and i also tried dumping fuel directly into air intake but no change. i checked for spark by pulling one plug wire and putting a plug into it and cranking and this looks fine. i tried swapping in a used fuel relay and ovp relay no change. i did determine that i have a flow of fuel to the inlet of the fuel distributor but when i pull a fuel line at the #1 cylinder fuel just dribbles out. i see two electronic parts attatched to the fuel distributor how do i test them? or am i overlooking something else? i have a fuel pressure guage but dont know what it should be or where to test it. Thanks for the help
