The engine starts but then immediately stops
I am Japanese.
Please forgive me if my English is strange.
If there are any parts that are difficult to understand, please let me know and I will retranslate them.
Nice to meet you, please help!
Vehicle information
W212
2014 model
E300
212255C
M276
It is right-hand drive.
The engine starts immediately without any problems.
Immediately (1-2 seconds), the idling becomes unstable, a hunting-like symptom appears, and the engine cuts out about 5-10 seconds after starting, and it cannot be started for a while.
When it cannot be started, it will crank but there is no sign of ignition.
If you turn on the accelerator while it is hunting, it will not stop during that time.
What I have done so far is
6 spark plugs
6 ignition coils
4 camshaft position sensors
4 camshaft solenoids (magnets)
.
The following error codes are detected by a simple diagnostic device.

Your description reads exactly like a low fuel pressure issue.
Can you pls read fuel pressure both at tank and rail using data scanner.
codes are next to meaningless without context:
- status active/stored
- humanoid description
- modules name
- live data
What mileage is this engine : young or old ?
Campaï.
