I have a 1995 chevy blazer v6 4.3 vortec and it ran ok but we had to start it with starting fluid. We replaced the fuel pressure regulator and now it wont run for more than a few seconds. Everything is hooked up we replaced the fuel pump, map, maf, and tps sensors it seems like its not getting gas but theres no leaks. Checked the fuel pressure before and after fuel pump change and its the same 60 then it leakes down very quickly. The car is throwing codes 22, 34, and 43 for tps, map, and knock sensor. Could my knock sensor do this? Is there something else I should check?
