Here are the fuses panels BJB is under the hood and CJB is under the dash 1st diagram is the battery junction box and the 2nd and 3rd are the central




If you are looking at the BJB You only have a 21 ignition problem

If you are looking at the CJB You only have a 30 fuel filter or wastegate either a failed part or chaffed wiring harness reply if needed to clarify fuses I may be able to get you some more diagrams

I don't know what a BJB or CJB is on your reply??
Expert:  Chris (aka- Moose) replied 10 years ago.

BJB is the battery juncyion box it is the fuse panel under the hood

CJB is the central junction box it is the fuse panel under the dash

You said fuse 21 & 30 were blown

The reason I gave you the diagrams was because the BJB (top picture) does not have a 30

The miidle pic is the CJB and the bottom pic is the CJB fuse desription and there is no fuse 21
