Car runs fine. Motor runs like a sewing machine But will just die randomly. Most of the time it will start right back up, but some times when it dies you turn the key to stat an nothing happens. Wait a while and it will start again. I replaced the alternator because it was not charging. The only code was the O2 sensor as it had two of the four wires broken. I just replaced it today. Car died twice while idling. Started right back up. I did notice that several times in a row I tried to start the car and nothing. Turn the ignition on lights and everything comes on but nothing when turned to start. Fourth or fifth time motor turned over and stared right up ran for about 5 minutes and shut off. Started right back up rand for a while and shut off again. 3rd time started right back up and ran for 20 minutes before I shut it off. Started right back up. Checked for codes and nothing no codes what so ever. Nothing on the live data feed that looks off. I got nothing. I am out of ideas so I am hoping someone has an idea and can point me in the right direction.

 

Maybe a bad connection at the crank position sensor, hard to tell..

 

I think would see it in the codes or at least the live data.

 

Have often heard stories of intermittent stall or no start
And it was the crank sensor. Of course no DTC codes when scanned.

 

Crank sensors don't always throw a code.
Chances are that is the cause I agree.
The way that is confirmed is to hook up several leads to various sensors and record (Graph) their function over time. Then we look for the info that dropped out first.

 

I can look into this further. Usually a CPS will let the engine crank but not fire, and yes I could see that causing the car to shut off. The part is fairly cheap maybe I i just throw it at it and rule it out.
