Hello folks,

Another tricky one I have with my Camaro SS 2011. This car starts to drive me crazy.

It usually starts fine and runs well.
But when I turn it on and off a couple of times in a shorter period, like when I drive to a several stores, park, go shopping a couple of minutes and continue my journey it won't start.

I uploaded a video here: https://embed.api.video/vod/vi4wGJiGAqWiaEM8plQ6V46M

It cranks buy just dies. Than it shows the service stabilitrac warning light.

If I wait 20 to 30 minute it will start normal again.

The car gives me an error code for the CKP sensor when I scan it.

First I changed the CKP and CMP sensors with original GM parts.
Next I replaced the starter.
Than I replaced the CKP again. You better make sure heh

Unfortunately the problem persists.

Any idea what to test next?

There are quite a few possible reasons for the stabilitrak error. I'm still chasing mine. Some report that wheel speed sensor could be the culprit or some chaffed wiring. First thing to check is your battery. Do you have headers? Some of them can rub or melt wiring on the passenger side of the engine. I'd check those first. If not, take it to a good mechanic with an advanced scanning tool or the stealership. They'll be able to tell you which sensor is actually faulted. I'm trying to get mine in soon.
