Why do you think you need /have that one? What other diagram led you to this conclusion?

I thought that this ECM Ignition Fuse was the reason that my Pickup wont start ... I did a Tune up and replaced with new Denso OEM parts = NGK Coil, Fuel Pump - Filter,Battery, Denso Iridium Plugs,EFI Relay,New fuses,sanded all contacts to distributor cap & rotor .sanded all grounds clean,.Lots of testing with my VOM... I am Not getting fuel or spark..I am stumped.

Also were you having issues prior? Replacement of pump and efi relay not exactly "tune up"

grob that last picture in my list (jpg) is supost to be my fuse box and it shows a small attached mini box connected to my main fuse box under the dash... BUT my trucks fuse box does not have this... I wish that it did because I could replace the ECM - IG Fuse that I think is burned out.
I wish someone knew the other location.
I have checked and replaced as needed all fuses... under hood, under drivers side kick panel.. also behind the glove box ... also I saw a relay there as well ?? hmmm could that be the Circuit Opening Relay ? COR ?
 
I chased a similar problem, ended up being the circuit opening relay. ECU fuse blew in the process. It’s there, just keep looking. I had trouble finding th cor behind the glove box on my 88 3VZE
