Then obviously you messed something up in the process. You need to go back and check everything you touched.

dbl check work- is rotor spinning? seated correctly? spark at several plugs?
Being 15years old you may need to retime - did you mark #1 plug on old cap OR just replace wires according to diagram?
It is very possible the dist was moved replaced and the diagram reference for #1 is not really #1. Meaning #1 is not the same place as in picture.

If it was running before you did your repair, you did something wrong or you have defective parts.
Do you have spark using a spark tester at the end of the plug wires?

I'm pretty sure the parts are good, engine has been rebuilt, I established first cylinder and combustion side of compression. What would be next steps?

Was the engine running before you did your partial tune-up?
I am assuming you mean you located number 1 cylinder and it is on its compression stroke. If that is the case, the rotor in the distributor should be pointing at the number one plug wire king pin on the distributor cap. Verify all your wires are installed in the correct order as in the picture. Then see if it will start. If it doesn't, check for spark at one of the plug wires using a spark tester.
The SPOUT (spark out) plug is removed when you go to adjust the base timing using a timing light.

Yes it was running. It's been overhauled by the guy I bought it off of, if someone overhauls an engine and changes the order what might they change? If 1&4 2&5 3&6 which way would they most likely go?

You can't change the firing order of an engine. The way the engine's crankshaft and camshaft are machined dictates the engine's firing order. The firing order of that engine is 1,4,2,5,3,6.
The distributor has to be installed with the rotor pointing towards number 1 on the cap while the #1 piston is a top dead center on the compression stroke. The wires have to be connected as they are shown in the diagram. It won't run or run correctly if your wires or rotor isn't indexed correctly.
If it was running before you touched it, you have something installed incorrectly, you left something disconnected, or you have defective parts. Don't make it complicated.

I've wired it up right. When I've checked the compression and it's at the top of 1st cylinder the rotor pointing between 1 and 6. From front of engine 1 wire at noon wire 6 at ten rotor at eleven.

If you believe you have the wires and all that connected correctly and the engine still doesn't want to start, you need to follow the steps in this thread:

Could be the other guy installed the distributor a tooth off and instead of putting it in the right way moved the wires instead.
