1989 Chevy S-10 won't start

[raydqt]

At first it started hesitating a little bit for a couple of days. Then it really hesitated and it took about 5 minutes of trying until it finally start it but the check engine light statyed on. I check the codes and it showed #33, and 34 which talk about the MAP sensor (which I replaced) and #42 which is the HEI module which I checked and seems to be working right. In addition to the above I have also replaced the fuel pressure regulator but it still doesn't work. It looks like gas is getting all the way to the fuel pressure regulator but (gas comes out when I take it apart or I can hear the chamber filling up after I put it together and turn the ignitiojn) the injector does not inject. Any suggestions?

One more thing, a few times when I turned on the ignition I could hear a raddling noise by the carburator. One of the components that was making the noice was the injefctor and it kept injecting even though the engine was not running.

if the injectors aren't firing replace the module.
