I have good spark coming into the distributor from the coil but none coming out to any plugs. I have swapped the cap. Rotor and the camshaft position sensor under the cap still nothing. Thanks

Hi, thanks for the donation. If you take the coil wire loose from the cap and hold close to engine ground, engine cranking, can you see a spark jump.

Engine cranking, does the rotor turn? All battery cables and engine grounds, ok?

After rechecking I find a very weak spark. I removed the coil and checked resistance per the manual. Secondary ok, primary slightly out of spec 1.3 vs 0.96-1.18. Is this critical?

A weak coil is a possibility, plus the other suggestions. Sorry about the late reply, I've been having problems with mail.
