I got the code 54 using GM Code reader and i also had purchase the Actron CP9690 but when i connect the Actron CP9690 it does not turn on why doesn't it turn on?

The Manual say Fuel circuit fault or Mixture Control (M/C) solenoid fault or Electronic Control Module (ECM) fault/EGR solenoid #2 failure 3.8L VIN1)

The Car doesn't start but i don't know which one of these part is the bad part does any one know?
