Question: Blazer fuel problem?

My 95 chevy blazer at first started with a simple problem it would not hold its prime so we had to spray starting fluid in the throttle body to start it. we replaced the fuel pressure regulator and now it runs horrible it will not stay idling very long and pops and backfires. can anyone give me ideas?
