Well, I thought I had this sorted with a new MAF sensor; however, on a drive the other day the engine shutoff. After a tow home I restarted the troubleshooting. The engine has no spark. Tested the coil which is fine, and both plug wires are fine. I pulled the DTC's from Protune which shows errors on the MAP, Intake Air Sensor, Throttle Position, both O2 sensors and Stepper Motor, although not all at the same time.
In reviewing the S&S wiring diagram I see all those share the same 5V sensor ground wire. If there is a short on that ground would that cause the engine not to spark?
Thanks in advance for any thoughts.
