Benz w203 Crank but won't start FIX🪛🛠 

All the best brother glad to help.

Yes the fuse are the same what u do is remove the faulty at the back, in front you'll find more similar fuses check your fuse sheet from the side of the dash. Locate a fuse similar to one faulty which has less function swap the faulty with that one remember to label them so you can replace the faulty one later. I sold the vehicle unfortunately I can't duplicate the video. Good luck.

No this fault did not since my engine light was already on due to Mass Airflow Sensor malfunction (it went of after MAF replaced).

Yes all i did I swap the relay fuse to the front there are 4 x similar fuse to the fuel relay, car fire once issue gone. Remember to mark the old fuse since they look the same hope your it's fuel relay also, but you'll know if when key turn to on position listen to back seat for fuel pump sound if no sound then its the relay. If relay changed the issue not solved have a look at the fuel pump. Good luck

@@jeff-zn thanks, pump not working, this model has a shit fuel tank. the upper is the pump and the lower is just a sensor. not very smart solution. and why does need two sensors? very unlogic. i'm thinking about cut out the 'just sensor' and change place of the pump for the lowest place of the tank

According to the car's computer there is no fault on your vehicle even though you notice a fault. The engine light you see on my vehicle is caused by a faulty MAF sensor, it is located on the air intake pipe to the throttle body.
