Can't get the engine to fire................Help, please.....

It sounds over simplified but you must determine if it is Fuel or Spark deficient. Start by pulling some plugs After cranking several seconds; are they wet?? If so go that would indicate the injectors are functioning. Next go to the Ignition system; lay a plug with wire attached on a grounded surface such as the manifold, crank the engine and watch the spark plug gap. Is the coil (assumed good??) compatable with the spark box being used (Crane/MSD). The incorrect phasing of the rotor wil NOT prevent it from firing the plugs. It may not start or it may run poorly but it will trigger the spark box as long as it is spinning.
Where are you pulling the switched 12 volts from? This is the source for the small red wire on the MSD box, not to be confused with the heavy Red & Black wires that actually powers the MSD. It has to be HOT with 12 volts while cranking and in the run position. Without that you are dead in the water.

the battery got weaker and weaker

I have been keeping the battery on a trickle charger and have been trying to keep an eye on it as I go.

The coil sparks when the ignition is first turned on and sparks, with a beep coming from the distributor, once or twice when the ignition is turned off.

Fuel was a problem as I had a regulator that would only put out 7 psi, I have since changed it and now have 45 psi.

The plugs are not sparking.

I'm going to double check

and see exactly where this is routed to tonight when I get home. I think I have checked this but now am second guessing myself

Now I remember why I run a carburetor!

I know, I know, not helping!
