It's a possibility. I went through the engine but couldn't find anything chewed up. Maybe something got wet?

 

I was able to pull code and I'm receiving P0335 Crankshaft Position Sensor "A" Circuit.

 

This may help you with your problem.

No luck. Any idea where the crankshaft position sensor is located?

 

It's by the front of the crank on the side though, look for a small wiring harness that goes into the timing chain lower cover. I don't know if a problem there will cause the light on the push start button to not light up though, if you have an open there it wont start but wont cause any of the problems like flickering lights etc.

 

Not your engine but they're all basically in the same spot, where it says crankshaft position near the bottom.

 

Thanks. Is it easier to access from beneath?

 

Might be tough if you have AC

 

I do have AC.

 

Clear the code and see if it comes back immediately (hard code) I wouldn't chase that too far if it doesn't.

 

I attempted to clear it and it's showing as permanent.

 

I'm just using a blue driver reader.

 

So the code comes back when clearing it and then turning the ignition on with no attempt to crank it over?

 

It won't allow me to clear the code. It's showing as permanent.

 

Did you ever have that second battery load tested?
