New head gasket. Now truck won't start

So my engine blew out its head gasket. I replaced the cylinder head with a new one from enginebuilder that came with new valves and cam installed. Also got a top end gasket kit. After 3 days of leisurely wrenching on the rig I assembled everything in the correct order (I labeled everything before removal). Now that my runner is back together I turn the key and the starter works, but no action other than that. I have Installed new plugs, plug wires, and distributer cap. All the battery connections are tight and right. What did I miss? Please help. And thanks for any suggestions.

Fuel, air, spark. It's that simple.

I'd start with checking ignition timing. If you got the distributor off by one tooth, that will move the timing 28°. And if you put it in out 180°, well, nothing will happen.

If the timing is right, pull a plug and see if it's wet. If not, you may not be getting fuel. Eliminate the COR/VAF/Fuel pump loop by jumpering Fp to B+ in the diagnostic connector (with key-on, this forces the pump to run). Plugs still dry? Try a little starting fluid (go easy on that stuff: it'll give your engine cancer. Probably you too.). Or use a noid light to confirm the injectors are getting signal.

If the timing belt is way off, you won't get compression. This is a hard mistake to make, but you can check for it by checking compression.

Ok. It was the timing. Got set 180 off. Turned the distributer to the correct position. Set the timing right and it works
