Pull the distributor cap off to see that the rotor is turning when cranking it over.
Start with the basics.
Rock the crank back and forth and watch the rotor to see how loose your timing chain is. Possibly the chain jumped a few teeth if it is loose enough, throwing the mechanical timing out of whack.
I will check that, but the distributor is new along with the timing chain, I know that doesn't mean a lot when things happen but just wanted to throw that out there.
