Coil Pack On Fire?

[zertek]

Hey guys,

My R32 drift car decided it didnt want to start the other day (The motor is an RB25det) so i had a look today and found a problem.

first thing i noticed is my spark plugs were wet with fuel, so this tells me im not getting any spark. As i got to the last coilpack and spark plug i noticed alot of charcoal around that area of the valley. The spark plug was all sooty on the section where the coil pack connects, i then looked at the coilpack itself, the rubber boot was a bit warped and the previously blue silicon it was covered in is now brown. (I've coated all the coil packs in silicon to prevent waste spark.)

so there is a problem with this coil pack. But i still cant workout why the others are not firing? I checked the ground wire that connects to the rear coilpack bracket (the one that has been cooked). and the wire seems to be fine. If the back coil pack is screwed, the other coilpacks should still work thus allowing the car to start and run on 5 cylinders? or am i wrong?

cheers guys, any help welcome

If you have a multimeter check the output on the coil pack plugs to see if you getting 12V with ign on and constant earth, then crank it and see if your getting a firing signal earth from the ignitor.

I would agree that the ignitor is probably damage after that but. I don't think it has anything to do with the silicon you have used, just a coil pack gone bad. If you don't have a multimeter just rig up a 12v test light will do the same job.
