Lately my '21 with 61K miles occasionally stumbles when first starting like it's not getting fuel. The last time it happened it threw a MIL code (Crankshaft Position Sensor) after starting up and then it was flashing a warning that the hood was open. Of course, it wasn't.
I cleared the code with Jscan.
Several times since then it's stumbled when pushing the start button, sometimes having to press the start button two or three times. Same check engine light, same code, now sometimes with the display saying "Start/Stop must be on".
This morning I cleared the code again but noticed the "Permanent" one was gone. I drained the fuel filter, checked the CPS cable and connector, and primed the pump before driving it today and stopping / starting the engine several times with no issue.
Other than the weird combination of errors and stumbling on startup, it's running great. Main battery is two years old and I've had the Aux battery bypassed for over a year.
Any thoughts?
