Default 1994 b2300 engine code help!

got this truck as a Holmes me over till my 1980 gets painted.

engine light comes on after 5 minutes or so after I start driving. i followed some youtube video to pull codes by jumping the EEC with a wire. it flashed some codes.

I watched it over and over and over and over, taking notes. below is the flashes, number of flashes, - dash to signify a brief pause, then the number of flashes.
1-1-1-1-1-1-1-3-3-2-3-3-2
so, one flash, pause, one flash, pause, one flash, pause etc etc
it spits this series out then just stops, does not repeat until I turn the key off then back on.
this is key on engine off. when the wire is jumped it will not crank/start.

I have no clue what it means.
can you please please help me???

There should be different "lengths" of pauses between a series of flashes.......you need to let us know this. A half-second pause will be present between each flash to display a certain digit.......then there will be a two-second pause between each digit.........there should be 3 digits per code, for a 1994 model year.......so you need to identify the "length" of the pauses so we can figure out what the code numbers are.

Looks like your phone screenshot is from this page.......

https://www.troublecodes.net/mazda/9...r-navajo-4-0l/



Read all the way through the instructions on that page to understand how the code digits are "displayed".........then click on the link at the bottom of that page that looks like this.....

EEC-IV

and you can see what each of the 3-digit codes actually mean.

Let us know what you find out.
