Ignition coils

Hi,

These codes are telling you that the Ignition control circuit is open. Meaning there is either a wiring issue or a ECM issue at this point. The fact that you have all 6 I would think the ECM is to blame. If you look at the attachments it explains the circuit control. Then the wiring diagrams show it is a direct feed from the ECM to the coils for these.

Again, the fact that it is all of them it is something they all have in common and that is the ECM. Even the power feed and ground are split on even and odd cylinders. However, this is not saying that is the issue. This is directly condemning the control circuit.

Let me know what you think and we can go from there. Thanks
