When I start the car it runs, give it gas it dies. I have changed the fuel pump, modular, idle position sentor, computer, map sensor, crank sensor, coolant temp. Sensor and oxygen sensor and still have the same problem.

Check for weak coil. Pull wire hold to block should have blue/white spark.

Injectors replaced? Cleaned? Take a timming light shine on inj pattern see if it is 360 deg and no drips. If not then that will cause what GM refers to as tip in hesistation.
