261 no start

[62stepside longbox]

Hi everyone I've been having some troubles starting my truck. Initially I thought it was the carb, so I put on a 2 barrel ( was going to do it anyways). After a while of messing around with it I got it to start with the two barrel. Ran fine, shut it off, fast forward a couple weeks and It won't start and the carb is leaking (it was free) so I took it off and completely cleaned the original carb and put that one on. Still wasn't firing sprayed some starting fluid down the manifold and still nothing. So it seems that now I'm getting no spark. After doing lots of testing with the multi-meter I concluded that the spark plugs are good, the coil is good and half of the spark plug wires are pretty bad, especially the one going from the coil to the distributor. So I put on a set of new plug wires and trying starting again but still nothing. Could the distributor be my problem? Any ideas what else could be wrong? Any help is appreciated. Thanks
