1989 s10 blazer will not idle

I have a 1989 s10 blazer that would occasionaly backfire during acceleration. One day it died and would not start and stay running. So far I have replaced the distributor cap,rotor,spark plugs,plug wires,timing chain and map sensor. My problem is still that it is hard to start, Once started it will not idle. In order to keep it running I have to rev the engine. Can anyone suggest how I can find out what the problem is?

check the setting on the automatic choke . loosen the 3 screws on the mounting ring and turn the cap a few points to allow the choke to come off earlier.. If it is heated by pipes from the manifold ensure that the hot air is getting to the choke operating bi-metal spring. If electric ensure that the current is getting to the heater in the cap.

You may have a bad idle air control valve, I would also check for a vacuum leak, from a vacuum hose or a broken vacuum tee.
