please pm me with help if so thanks .....

have you checked your plug gap? a gap to small can cause the coil pack to short out. im not sure what a shorted out coilpack looks like but maybe they do that?

Now that has to be the 8th wonder of the world.

It looks like the coil is melting. You should throw a multi meter on it, use the voltage setting since the ignitor will be sending volts. I think it is a fair assumption that either the ignitor or the ecu is sending a signal that does not get interrupted/is constant.



maybe try running the car on five cylinders with the injector pulled off the number 1 cylinder. Then verify the signals a good cylinder is getting against the signal the bad one is getting. Trace the problem until you end up at the ecu or at a location grounding out that should not be. Check the coil harness while you are at it.

i run the same gap in my car for the 25lbs of boost i run and never had this do this to any of my coilpacks.

we have a big feeling it's the main harness.... but where to start..lol

it just started doing this yesterday and hes drivin it a few time already
this year so...

thanks for your tips...

same thing just happened to my gtst with rb25 ( it was my #1 coil too), I know its a wiring problem because i have been rewiring my whole harness. My first place to check is the coil negative and earth. Could it be that the coil is grounded improperly and finding its own way to ground (shorting)?

Jeff did you find the problem on yours I have been having the same issue. changed the coil pack, fried again with in 3-5 minutes of running so we checked the power transitor it had one pin with a different ohm reading so I replaced that with another coil pack still again fried pack. I then swapped the #2 coil pack and plug to #1 location in case #1 plug was bad but fried pack again they it ozzed. the harness after power transistor is good checked all that is left is ecu and

It is probably a bad ground due to cracked insulation within the oem wiring harness. You guys should check out my LS2 coil thread and get me to build you a harness

Check for a short in your harness.


Oops didnt see the age of this...
