Post SBC Runnin like junk

Hi, I have a 91 sbc with throttle body injection. I recently had a fuel pump go bad and replaced it. Shortly after my car died and I replaced the fuel filter and all was well for about 25 minutes. After that time period the car would only goto about to 2500 rpm and had no power...but would idle fine. Now the car is not running at all, bad TB injectors? HELP!!

does it have a fuel pressure regulator?
i dunno, i know drive line.
you should be able to jump out 2 prongs in the aldl to get trouble codes from the ecm.
i don't know what the procedure is off hand, i have done it a couplea times tho. if no one else knows, i can find out.
i bet some one will know.
i hope this is some how helpful

Did you bleed the fuel system? Sounds like you have an air lock. Do you get fuel at the rail now?

there should be a tirevalve type bleeder near the TB push the pin and turn the engine over till all the air is out,if any air is in it you won't get proper fuel pressure(air is compressable,liquids aren't)
