Then move the dist around a bit while cranking. SLOWLY!!! See if you can find a spot where it fires. I do it another way. I TDC #1, advance 10*, stab the dist in where I want it, remove #1 plug, install #1 wire on it, and ground it.
DO NOT CRANK ENGINE. Turn on the key and watch the open spark plug while you turn the dist. When the spark snaps, put the plug back in and it's close enough to start.
