Hello all, about an hour ago i finished installing a new feul pump and filter (pain in the ***) and a 40 series Flowmaster Muffler in my Camaro. i started the engine after letting the pump prime and it still runs like it had the same pump, running for about twenty seconds then sputtering out.. its getting on my nerves i had plans to get it painted soon and everything. anyone have any suggestions on what might be going on here.. its rediculous... pleased help..

Check the fuel pump relay for starters. After it sputters out, is there any fuel pressure at the TBI?
After starting, check the injectors til it dies, and see if it quits spraying fuel into the barrels. When you changed the pump did you also replace the wiring in the tank?
