Mechanic Job in Woodstock, Georgia

In need of someone trouble shoot an engine no start issue. In a 86 chevy k10 with a 305. There was a weird noise coming from the timing chain area, so I replaced the gears, chain, cover, hamonic balancer, water pump, and fan clutch. And all be, but now no start. Truck cranks but wont start. Have also replaced plugs and wires and the ignition coil. Have good spark, battery that tests good, and even startery fluid doest get it going. I'm at a lose. Hopefully someone can come out and help get to the bottom of this. Thanks
