I have a 2004 CLK 320 it was running hot and smoking after I put in drive and put it into the garage. I swapped the engine the car no longer turns on now it cranks no starts. I got a code P0335. I changed the crankshaft sensor 3x, changed the harness 1x, change the computer and reprogram 3x, change the flywheel 1x. Check the timing chain and timing is right. I still I have just one code which is P0335. I still have no sparks on spark plug and one code that scanner shows P0335. Please help.

Also asked 3 professional electricians they give up.
For background I've been a mechanic for Mercedes for 40 years never had an issue with engine swaps.
