2007 mercedes e 350 not starting
I have a 2007 mercedes e 350 the car many problems suddenly happening for no reason. Sometimes when i try to start the car it would not start it cranks but there is no fuel so the fuel pump doesn't work but when i reset or reconnecting the battery it would start. When it starts it is good until suddenly it would throw check engine light for evap problem and cam shaft positioning sensor. The other problem is that sometimes it would stall for no reason but it turns back on again after a couple tries. When this happens it would misfire in all cylinder and the engine would start shaking. I assume it was the fuel pump so check the fuel and the relay but it was good and i also swap a new fuel pump on it but it didn't change anything. It drives fine for a couple of minutes or hours but the problems would come back so i have to clear the code for it restart. I think there is possibility is the crank positioning sensor and ecu and rear sam but i don't know if that's cause
Does anyone know how should i fix it
Thank you

I scanned it those are the codes that they show up at the same time after driving it for a day. The car is like good one day the other is showing problems i used an scanner for each part of the car but shows no code but these codes but it goes away after clearing it and drives fine but after a long drive when i come to a stop this happens. I checked all the fuses and everything is good. I think there is a chance that a crank positioning sensor is bad because it can throw a wrong code to the ecu and make the fuel pump not be activated because when this happens and the car doesn't start i add fuel from the intake it starts.
could the crank positioning sensor throws no code but it goes bad

Might be worth looking into the possibility of whether or not this car is among those which suffered from timing chain sprocket problems. The sprockets wear prematurely and cause running problems. Eventually the engine will fail totally. I'm not sure what the diagnosis process is but if you first of all find out from the chassis number of the car whether or not it could be a problem on this one that is a good place to start. i.e. if it's not part of that set of engines with that issue then look at other possible causes... if it is part of that set of engines then further diagnosis required.
