Help, no spark and no engine troubles codes

[CarlosPTR210]

Hi,

Yesterday I go to peroform the smog test to my new 91 supra, and the car pass it .

But today morning, the car donsen't work, Check engine codes but is clear of any truoble.

So then i check from some wiring conection, coil pack, resitors etc, and are fine, then try to star the engine again and found that have no spark, check engine codes but dont show any one :S.


What can i do?

I would check the resistance on the cps and then check the connector going to the cps. The plug on the cps and harness side get baked and the wires burn into.

With ignition switch ON
