Lots of things to check before buying parts. Engines need compression, fuel/air mixture & spark at the right time to start & run.
You mentioned you replaced lots of goodies, but not if you have sparks. Pull the coil wire off the distributor & hold it near an engine ground while someone cranks the engine for you.
You replaced the fuel pump, but did you check if there was fuel pressure before spending the $? or whether you have fuel pressure now? Pull a spark plug & have someone crank the engine while you put a thumb over the spark plug hole for a crude compression check. Look at the plug while it's out. See if it has unburned fuel on it.
If you've got compression & spark, try a (very) little ether (starting fluid).
Spend time checking things before spending dollars replacing things that you don't know are bad or not.
Let us know how you're doing.
