I have a 2.0 4cyl carburated engine. i can crank crank and crank but wont start. there new plugs fuel filter & the carb has been rebuilt.
Check for spark at the distributor if no spark check or replace coil pack. also check to see distributor is turning while engine cranking, if not, possible worn out or broken gear tooth on shaft inside engine.
if distributor turns, check for burnt or worn out points and/or contacts on distributor cap.

Have you tried dumping perhaps a soda cap quantity of gas directly into the carbeurator?If you do that and it fires,you likely have a gas flow problem.If it doesn't fire,loosen the top half of the distributor cap.Have someone try to start it while you slightly turn the distributor cap in both directions,perhaps as much as 1/2 of an inch in each direction.In the old carbeurator engines,that was how you had to time the ignition.Other possibilities are the fuel filter,I am not sure if there was a fuel pump relay in those days,and maybe air in the gas line although it sounds as if you have probably already tried to start it enough times to get the air out.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.I really encourage responses so I can follow up properly as I know where you stand and asking someone else restarts all the explaining because we cannot see other 'Expert's' responses.Good luck,Greg

I had a geo metro that sat a long time and the gas turned to varnish. You will need to drop the tank, clean out the gunk, put in a new fuel pump and and filter and flush the fuel lines out to the injectors.

Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.

Check for spark. Does the distributor shaft still turn when cranking? If you have no spark at a spark plug, the ignition system has a problem. Possibly the coil or ignition module. Test before replacing, it saves money.
does it have a point distributor or a electronic distributor
