My number 1 and number 4 cylinders are not firing. 2 and 3 fire perfect, new CAS, and just replaced the ICM but 1 and 4 are still not firing. I switched the coils and still the same thing so both coils are working but on the ICM plug I tested the pins with a test light and im only getting power on pins 1,3,and7 I believe I know one is a ground but is that how is supposed to be or am I missing something?
