Coilpack Problem ?

[Dj Ryderz]

So my car run only on 2 cylinder. I interchange the coilpack to see if its blew and its the same thing.

The coil are good. All my setup is brand new and was fully working 2 day ago.
I havent touch the wiring and my computer is a power fc.

If its not the coilpack what could it be ?

CAS
ECU
Anything Else ??????

Thx for your help.

Btw its a sr20det freshly rebuilt.

Could be CAS or ECU, but if it's only two cylinders, my first thing to check would be the Ignitor Chip.

Not to step on toes or anything. ;) you need to work backwards from here, do a power balance test for fuel, you already know which cylinders but since the coil checked good, its either plugs or fuel injector from there.

If, fuel and plugs check out, test the wiring. it could be the ecu or cas, but if the initial cause is fubarred wiring, you'd either get the same result or fry the new ecu.

Personally I think the cas is a stout piece, wouldn't write it off, just yet... My cas has had a broken ear for 4yrs. I know not the same but whatever!

thx guys for the fast response . I'll check tomorrow for the cas and ignitor chip. For the fuel system everything is brand new (pump, hose, injector etc) but i will check that as my second option.


Thx again

I found the problem.... I feel really noob about this but it was the sparks plug.

At first i've not thinking of that because they are only 30km ... anyway i'm glad to hear the sound of my motor again :)
