Starting Issue - Cold and Hot
I've researched the forums and noticed the common hot start issue but my problem is a little different and I'm looking to see if someone has found a fix or has any ideas.
Car cranks for a long time before starting. When it starts I get the crank position sensor code as well as all the stabilitrak lights and no tachometer. This happens cold or hot the same way. Battery is brand new and I tested the voltage of the battery when the car is running and not. Voltage rises as it should when idling so I suspect alternator to be fine. My assumption is the long crank drains power resulting in the tach and stabilitrack issues. Please let me know if anyone had a similar issue on cold starts. |

I would fix that Crank sensor code first.That would cause the tach to go out also.Probably just a crank sensor.

I dont believe its the actual crank sensor. I dont get that code every time and if I clear it, it stays off for the rest of the drive.
Update: I added the secondary ground in the trunk and will be adding the secondary ground between the engine and frame today. No change after the trunk ground was added. |

Did you end up fixing this issue? I am experiencing the same issue even after replacing the crank sensor, and adding the extra ground from the engine to the frame.
