Chevy cruze turbo diesel 2014

Being a diesel, I was going to say it doesn't have one but it does. The crankshaft position sensor would have to be located where it points toward the flywheel, on the driver's (left hand) side of the engine I believe. But if you don't have trouble codes P0320 and P0340, I wouldn't worry about it. If it is running poorly, check your fuel filter,

Actually haves a code p0336 is the crank sensor

But it turns on and not even 2 seconds it turns off by itself

It must be the crank sensor. I saw that it may be located near the crankshaft pulley. It "reads" off a magnet that rotates with the pulley on the passenger side of the engine.....not the flywheel like so many cars.
