My 2002 clk 320 will not start but cranks help plz!
I was just driving it about three hours ago then the check engine light flipped on at a light still drove all the way home shut it off then I waited I started it again fine I thought but check engine light was still on then I go inside three hours pass get in to start and it won't start but it cranks. So my question is. Would this be the mass air flow sensor or the crankshaft sensor or maybe even something else and help is appreciated. Thanks for reading!! Oh yea doing it myself so maybe an idea of level of difficulty

Newer cars like yours are capable of telling you what is wrong simply by reading the DTC with a code reader. A DTC is a Diagnostic Trouble Code.
Auto parts stores may loan a code reader to you. Also be sure to keep your battery charged (if not starting) by connecting a battery charger to it.

Nino, from my experience a bad MAF sensor will cause the Check Engine warning light to come on, but will not prevent the engine from starting. So you must have another problem. As Elektri recommends, you should read the DTC's before throwing parts at the problem or guessing what's wrong.

Put a crank sensor in it, you can test by hooking up ohm meter and heating up sensor to about 200 degress see if reading goes open

It is worth the gamble to go buy a CPS sensor at(only option on Sunday) Autozone here in the USA for 50 dollars, and change it your self...
Five minute job. You can even do it with a SAE 5/16" 6-point socket 1/4" drive socket.. better than 95% that is your problem.. PeachPartsWiki: R&R of the Crankshaft Position Sensor The other 5% can be the fuel pump is dead, but you can press on the sharader valve on the fuel rail, and watch the fuel squirt out-not dribble out.. Both are easy, you may need a flash light to find the sensor. It is at the rear of the engine on the drivers side.. Best of luck, Martin
