The DME relay is of course a two part relay. One side is for the fuel pump, the other side is the signal from the reference sensors.
The easy way to test your fuel pump is squirt some starting fluid like ether or carb cleaner into the intake when cranking. If it sputters and coughs and tries to start, you have no fuel pressure, and a bad fuel pump or no signal from the DME.
Get the solid state relay available and that will fix the relay forever.
The solid state DME relay is a upgrade any 3.2 should have even if it is running fine now. As far as tracking down the problem, that will takes some diagnosis. There are a few hundred no start threads. Read through them and you will see what to test, and how to diagnosis each possibility.
