Bob you gave me a wiring diagram for a 2000 s10 with 2.2 l engine and told me what wires to look for because it is only running on 2 cylinders. One coil is not putting out any spark. The wires ohmed out ok. If I remove both coils and hook a test light to the terminals where the coil that works would plug in the circuit board the light will blink while I turn the engine with the starter. If I hook the test light to the terminals where the coil that does not work plugs into, The test light does not blink when I turn the engine. This sounds like the computer is not putting out the signal to that coil. I think the computer is bad. Do you agree?
Thanks
