So, the 1991 and 1992 FSM's are different than the others when it comes to trouble shooting the ECU.

I went to our local king county library and found the following pics to help me out.


The first picture is of the pinout. The following pictures are some flow charts for evaluating the ECU. I'm struggling with these right now because I've got fuel issues. My question is below the first picture.





For reference, the "W" wire is a dark purple, while the E1 is brown.


Step 1 in the following picture, it says I should have no voltage when I short the B+ and B+1 and measure it with the E1. But I do in fact get a volt reading (12 v).

And the 2nd step of that same picture, it says I should get a reading, but I don't.

Does that make any sense to you all? What does this mean for my ECU?

You might have better luck in the '86-'95 section.

Holy cow how did I do that?
