Hi guys, I'm having a no-spark issue on an S13 motor. I searched this morning on quite a few forums. What I'm looking to know is:
Is there a powered input wire to the CAS from anywhere? last year I remember checking for power at the CAS and getting it. There's no power to the CAS now.
I ran a pinout on pins 40 30 22 31 back to the ECU and there's continuity.
I'm at a loss. I have no injector pulse and no spark. I posted on AEM forums this morning as I'm using AEM.
I also tested for power at the ignitor and coils, which were fine. Coils are grounded. All ECU pins which require gnd are grounded. All pins that are powered to the ecu are getting power.
I'm just stuck on thinking that the CAS had power last year and not now. I haven't run the car in a while.
Thanks,
