I've been around just not as a registered member. So, enough about myself. let's get to it.

The Situation.

Codes 11, 12, 21, 32


So 12, 32 are all irrelevant to my problem. They've been replaced and fixed. For code 11, I do have a new dizzy/cap installed, also its been checked for 180" out syndrome. We'er peachy on that. But I have no idea why its still throwing that code. Code 21 is the massive issue of s*** I have to deal with. But after checking around, splicing wires and what not. I've come across what I think could be my problem(hope). The connector that goes to the power transistor isn't getting no powa. which might end being a burnt wire(s) or, a broken ECU?

And if it is a wiring issue, Is there a DIY on how to replace them? Would hate to go and buy a new harness for just that s***.

thanks in advance fellow 2forty owners

Check that the battery has 12v and check your starter To see if it is good at your local auto store

UPDATE:

Anyone know how to unplug the wires from the ECM connector? It turns out that my gut feeling was correct. Hope to have this fix with in a day and have my s13 back up!!

UPDATE: UPDATE:

Wiring problem fixed.

If your not getting spark;

Check: Ground wire from transistor>check Power(Y/R wire) from the resistor for damage wire(s). most likely there was a surge.
