| I was able to get a used CAS but still no luck since the vehicle again shut off after idling for about 20 minutes. I went ahead and checked more wiring. I checked for continuity at the following locations... PTU sub harness to coil pack connectors ECU to PTU sub harness Ground on PTU Ground on coil pack connectors all checked good. Electrical power at the following ignition relay to coil pack connectors. I also checked for spark on the #1 coil and no spark after the vehicle shut down. I know that the O2 sensors were mentioned before but would bad O2 sensors lead to no spark or a possible bad ECU?I'm not sure what else to do other that to take it to a Z mechanic but there really isn't any one here in Virginia Beach that I might know. I will go ahead and swap the O2 sensors out but I just don't think this will fix it and I'm out of ideas so any suggestions would be greatly appreciated.
