HELP!! **BJB to CJB**

[jtroush2002]

does anyone have a wiring diagram for BJB to CJB circuit?
my number 2 and number 8 fuses (maybe other ones too) are out. I replaced those 2 with with brand new ones and I tested them but there is no current flow getting to them.
I need to trace this problem but I cant seem to find a diagram, I tried to follow the wires but they quickly disappear under the dash.

BJB= Batter Junction Box (fuse box by the battery)
CJC= central junction boc (under dash, inside car)

ANY input is greatly appreciated
Thanks

There are a bunch of power distribution diagrams in my Alldata, but I believe this attachment might be the one you are looking for:

Fuse 2 and 8 in the CJ fuse block are both related to Engine Controls.

What are your exact symptoms?

 

[jtroush2002]

thanks for the diagram,
but fuses 2 and 8 are not shown

you say you have access to most diagrams right.
well can I ask you to search for one that describes what fuse 2.0 and 2.8 do or their power distribution.
on the diagram above they describe fuse 6,8,24,30,36,28,34,43,20,26,43,20,26 and 32 which are some but not all. (or am i understading it wrong?)
Ill go home and look into this, I cant give it my 100% dedication here at work.

and as far my cars symptoms are those of a bad IAC, you know dies sometimes, rpm surges, smell of gas.
I get some codes, I get the EVAP VENT and PURGE control circuit malfuction code and all 4 O2's.
I know this is the problem because those fuses are not lighting up that and I changed the IAC (new one, from dealer) and 02's sensors

thanks for your help
keep it coming

Gimme a sec and I'll look through the ground/power distribution diagrams for one that includes the EVAP, IAC, and O2 circuits.

Ok, these should help. If you see a specific diagram reference number (ie. 23-1) just let me know and I will look it up.

 

[LaserRed01GT]

This might help as well.

I found this one...
do you have something like this?
this is as close as I can find to any diagram displaying that the 2.8 fuse controls the flow to all O2's and the EVAP.
I need the diagram that has this and tells my what wire color and thickness and stuff like that.
you know what I'm talking about right?

Whenever you are looking at these diagrams, they will show the primary wire color then the tracer (stripe) color. So this "GN/OG" would indicate a green wire with a orange tracer.

If you look at these two diagrams, it would suggest that the EVAP and HO2S systems are on the same circuit (117). I think you are on to something in that circuit. Look for any chafed or damaged wires that may be intermittently shorting to ground or with one another.

GREATNESS...lol
cool thanks
thats what I wanted to know...
I will work on it and try to trace it this week
hopefully this freezing weather gives up and lets me work on it.

Thanks again
