Yes, the electrical plug with three leads attached to the back of the dizzy is for the points. If that's not plugged the injectors won't fire. You can test with an injector removed from it's position (but still connected to a fuel line). Insert the business end of it in a glass jar and turn the ignition on. As Dave says, the fuel pump should prime for 1.5 seconds. Then crank the car for a couple of seconds to see if you get any fuel firing into the jar. If not, it's probably one of the following: pump not working, fuel pump activation circuit problem (relay, fuse, etc.), clogged filter, bad or disconnected points, injectors leads not plugged in, etc.

How are your grounds? There should be a three spade connector on the top of the engine, at the back near the flywheel. That's a multiple point ground. Make sure those leads are very clean and well connected.
