Thread: 2006 GP 3.8 NA Stalls Hard Restart

Hi first time post, Thank you in advance for the help.

I have a 2006 Grand Prix 3.8l after it warms up will intermittently out of the blue will stall. Everything in cab stays powered up. The car will not crank right after this happens until about 2-3 minutes later which it will crank over. At this point it will crank over for a while before it actually fires. when it does fire up it does so normally no sputtering.

What has done so far: MAF sensor cleaned, Throttle Body Replaced.

The information center has the following:
Throttle Position Sensor Faulty - Throttle Angle Sensor
Service Engine Light (MIL)
Service Traction Light

The car is unfortunately 3 hours away so cannot actually do any diagnostics at the moment.

Any suggestions and advice is greatly appreciated.

Thank You In advance again,
Chris

I mainly work on diesels and few cars. From what I'm familiar with, even if the crankshaft and or camshaft sensor is out the vehicle should still crank?? Maybe there is some kind of reset time built into the control module logic possibly?? Not sure. I was hoping the no crank after it stalls for couple minutes would help point where the problem is since I don't think there is much stuff that will keep the vehicle from cranking correct??

Not familiar with this exact car but this is based on knowledge from other vehicles I have worked on.

Thanks For The Reply,
Chris
