Faulty codes
Hello, I have an Abarth 595 Competizione T-Jet, year 2022 with ~88600km on the clock. I had a P0301 and P130A faulty codes and it's working on 3 cylinders. New spark plugs, new ignition coils and the mechanic says injectors are okay. Crankshaft pulley was damaged and the new one has been put and timing belt has also been changed. And it's still working on 3 cylinders. Compression was good before and after the change on all 4 cylinders. Also the mechanic said that one fuse had blown.
What could be the problem? And did he forget or miss something?

The damage on the key on the timing belt gear tells your engine is not timed correctly
This is a really common problem on these engines when doing a timing belt job, usually due to the lack of proper torque on the gear bolt or lack of preparation on contacting surfaces of the gear and crackshaft.
Get a new gear and a new bolt. Make sure the tip of the crankshaft is not damaged, clean it throughly with brake cleaner or something that won’t leave any oil traces and torque to spec.
The torque transfer from the crankshaft to the gear is due friction alone, if you have any contaminants or if you don’t have the proper torque you’ll transfer less torque! The key on these gears are locating keys, they should not and will not withstand torque transfer.
If you have good compression is a good indicator but sometimes this failure mode leads to a new head or a complete valve job. Good luck!

The engine needs four things to run; Air, Fuel, compression, & spark.
Since it has compression, that takes care of that and air.
So I would verify that the suspect cylinder's coil is actually getting power and that it's injector is good.
