1996 Silverado 5.7 Vortec blows Eng 1 fuse and has p0102 code
Vehicle Blows Eng 1 fuse and sets P0102 code.
It will still start and run.
Has new Maf sensor.
I disconnected O2 sensors,maf sensor,egr valve,evap purge solenoid,..20a fuse blows as soon as Key turned to on position.
Anyone had this problem before?
Ideas?

1. Check the ENG-1 fuse in the under-hood fuse block.
2. If the fuse is blown, check the Pink wire at or near the O2 sensors.
3. If the fuse is blown and the Pink wire checks OK at the O2 sensors, check for the fuse to blow with each O2 sensor disconnected.
4. If still the same, check the Pink wire for a short to ground under the hood, near the Mass Air Flow (MAF) sensor or the Cam Position (CMP) sensor.
5. If the fuse is not blown, check voltage on the ENG-1 fuse with the engine running.
6. If the voltage is low, check circuits at the ignition switc
