2006 Chevy Trailblazer Stalls while driving or sitting

Asked by Oct 27, 2015 at 05:57 PM about the 2006 Chevrolet TrailBlazer LS 4WD

Question type: Maintenance & Repair

I have a 2006 Chevy trailblazer that randomly shuts off while driving or just sitting there. Have taken it to 3 mechanics and they have no clue what is going on. When they plug into it to read any codes, the one that came back was the crankshaft sensor which was replaced. We've had the ignition switch, throttle body sensor(Think that's what it's called), crank shaft sensor replaced and cleaned the throttle body. Still doing it! Can ANYONE tell me why this is happening????

When it cuts off,does it crank back up ok?

I have to put it into neutral and it usually starts. Only a couple of times has it not. I would have to pull over and let it sit for like 5 mins and then it would start.

Have you had the fuel pressure checked?Sounds like you may have a faulty fuel pump,meaning when it gets hot will shut car down,it would be random depending on how much fuel you have in the SUV.

All so check the fuel filter.

We haven't checked that. The rpm drops and stops working sometimes too, would that also cause that to bre happening?

Once you vehicle cuts off,then cranks back up,it kills the fire to the pump for a few seconds,and then you are able to crank and go on a ways,

Yes it will make the rpms drop cause it is lossing fuel.

You know we have been to 3 different mechanics and not one of them ever suggested that. My husband and I are going to try that and see if that fixes the problem thank you so much for your input
