no spark cyl 2 and 3

[willnatale]

I have no spark in 2 cylinders. I don't know why I started the car yesterday no problem I shut the car off to put anti freeze in and when I went to turn it on it wouldn't start . I bought I new coil pack but its not the problem still no spark. There no spark at the plugs or in the wires so I assume and would be father back then the coil packs. Does anyone know why my cars doing this

Could be the ecu is bad if you have no spark, plugs, or wires, or connections.

It could be your power transistor/aka ignitor. See here http://www.dsmtuners.com/forums/electrical-tech/423041-dropped-2-cylinders-spark.html#post152827896

I second that, sounds exactly like what happened to one of the 1g awd i used to have. I replaced the coils and everything, and it turned out to be the transistor box thats bolted onto the intake manifold that was bad. When it goes out, one of the 2 coil packs usually stops firing.

Alright thank that sounds like a problem.. I'm going to buy one right now hopefully that's it.. does anyone know how this would break or it just happens over time

Seemed like wear and tear over time when mine went out. I drove about 5 miles from my house (i drove that car at least 5 times a week), halfway back i made a left turn and lost spark to 2 cylinders while driving. It was fine for 18 months + however long the previous owner of the car was running it, then just died at random, no impact or noteable event that could have caused it just a 20 mph left turn.

They are known for just randomly failing.
