Dead coil, tried 3 different coil packs

[onefast2gdsm]

So I recently did a wire tuck and cut some wires. I rerouted the wire harness along the firewall so it would be hidden. Power transistor is mounted under intake with a bolt to where the stay bracket would be for the intake.

I have a 6 bolt swap so my coil pack say 4123 but my wires are 2341. I am not getting spark on cylinders 2&3, I've tried 3 different coil packs and 3 different power transistors. Cas worked before the tuck and I even tried moving the power transistor back to the stock location.

The wires I cut were for the solenoids on the firewall, cruise control, and a blue plug that wasn't connected on my car. What does the coil pack tie into that might have got messed with when doing the tuck. I am at a complete loss. And yes I had my battery disconnected while doing this.

If I am not mistaken the blue plug is for the tach check. Did you cut it off , or did you cut off the plug and solder the wires together?
This might be your issue , if you just cut of the plug.

I just cut the plug, it wasnt connected to anything, and never was if I recall correctly when I first got my car.

yeah thats the test connector. Connect the 2 wire end together and it should fix your issue.

Basically it ties ignitor(black/white) pin 8 to pin 2 of the coil (blue/red) and you just cut that by cutting the test connector.

That is used for diagnostics , the usually hook up a test tach on it. But its not a connector in the normal sense , think of it as a vampire clip.

Thank you guys so much. I will give this a try later when i get back home. I still have the plug so ill just solder it back on.

 

[onefast2gdsm]

Well I soldered the wire back and its still not firing on 2&3. Any other suggestions?

These are the plugs I deleted

Anyone know if the evap,purge and fuel solenoids are in anyway related to the coil pack?

 

[onefast2gdsm]

Well I searched all night and didn't come up with anything. If someone knows what else ties into the coil pack it would be greatly appreciated.

The power transistor is responsible for the firing of the coils, but it needs to get an on/off signal from the ecu. If there is no signal to the power transistor it will not fire the coil.

Are any of the solenoids some how wired in to the transistor some how? I know Mitsu likes to use one wire for multiple things like power wires?

 

[ramsack]

Grounds and power wires are shared, so that won't cause your situation. You're missing a signal. You might just have a wire that is broken inside.

Resolved. Soldered the wring blue/red wire. Thought it was the check relay wire but it was for a solenoid. Found the correct blue/red wire and all is well. Thanks everyone for their input!!!
