Your resistance values seem just a bit high, but I suspect that the problem is 
in your meter, rather than in the PS. You should also measure infinity between 
ground and any pin.

If yours is a 70-73, turn the ignition ON and go to the engine. Push the 
throttle open while you listen. Each time you push the throttle down you should 
hear a series of clicks. Do you hear these clicks?

Carefully disconnect the 3 pin plug from the side of the distributor. Use an 
Ohmmeter to connect between the middle pin on the dist and one side pin. Have a 
friend crank the engine with the starter. You should see the resistance 
alternate between very high and very low. Repeat the test between the center 
pin and the other side.

If all these tests come out okay, get a pressure gauge and check the fuel 
pressure while the pump is running. You may have to jumper around the fuel pump 
relay to keep the pump running while you do this test.
