I replaced my accelerator pedal position sensor on my 03 trailblazer because reduced engine light came on and when gas pedal pressed it did nothing. with new sensor it still does nothing, what do I do

The most common problem on your trailblazer if it has a 4.2 liter engine is the cam shaft actuator gets stuck due to a clogged screen. If the reduced engine power light is on then the check engine light should also be on. You need to check for fault codes to see what step you need to do first.
