1970 Chevy Custom C Starting Problems

[djfugate]

Hello, I'm new to the message board and I have a problem ---
I just rebuilt the distributor in my 1970 Chevrolet Custom C pickup. At first it started, and then it ran out of gas. I put more gas in it and now it won’t start. I replaced the coil, but now it’s getting very little power from the ignition to the coil and it’s not getting any spark from the coil. I took the coil back and was told it was good. I checked to make sure it was seated properly, but I'm still not getting any spark. Do you have any ideas on what to do next? I have already checked the distributor cap, rotor, fuel filter (new) and they all seem to be working fine.
