Are you sure you are in the BJB ( aka Battery Junction Box , Engine Compartment
Fuse Panel ) ?
Fuse #23 & # 18 are powered directly from the PCM power relay, which uses BJB Fuse #2 to power the normally open contacts.
BJB #18 feeds :
- 2 inputs to the PCM
- IAC valve
- The Fuel injectors
- The Fuel pump relay coil ( normally open contacts to power the fuel pump is fuse #10 )
Did you do anything in the column aside from the MFs ?
I guess you could have damaged the PATS transceiver module ?
Best to confirm the fuses above are the correct ones, as if BJB Fuse # 18 does not have power on both sides like BJB #23, there is something very wrong.
