2010 MB C300 -Cranks no start HELP!!!!

Okay, so yesterday me and the family are out shopping for christmas, we pull up to get gas. While getting gas the car was running and it start stumbling and then died. I finished getting gas, went to start it back up and it turns over but will not start. I try a few more times and nothing so i call a tow truck. While waiting on the tow truck for about 30 min i tried again and it finally starts. Since im only 2 miles from my house i decide to put it in drive and try to get it home. When i put it in drive the car started to pull itself but the gas peddle was totally non-responsive and the check engine light came on. Going about 3 mph, after about 50 feet the peddle kicked in and the car ran normal. I drove it straight home and cancelled the tow service. When i got it home I hooked up my OBD II reader but was unable to pull any codes. Not saying it didnt have any, just that my OBD II couldnt read them. I tried starting it again and it cranked right up. But the family had shopping to finish so we took my truck and went and finished shopping. When we got back home hrs later i tried to crank it again and it turns over but wont start. Since I already had a Crank position sensor and 1 Cam position sensor in my garage that i had ordered with a bunch of other things the month before, I decided to go and get 3 more Cam position sensors and replace all 4 and the crank position sensor. Still nothing. The car turns over but will not fire. My next idea is in the area of fuel, but any suggestions would be great!!!! ANY AND ALL HELP WOULD BE APPRECIATED BEFORE I HAVE IT TOWED TO THE STEALERSHIP. Sorry for the long post.

You've likely damaged the fuel evap system. Chances are the purge valve on the charcoal cannister has been damaged/ stuck OPEN, and the cannister is flooded as well.

That would cause the car to stall or fail to start? When my W203 had issues with the fuel evap system there were no drivability issues, just a CEL.

Replaced purge valve and still wont start. It cranks and turns over and tries to start but just wont. Any direction or opinions would be great.
