It doesnt start first time i turn the key. I changed the fuel pump and filter last friday and it gives off a normal quiet buzzing noise sometimes.
Radio turns off at times and always turns off together with tachometer but quickly turns back on again

Voltage with car off: 12.8
Voltage with car on: 13.8

Pretty clueless at where to begin diagnosing issues

Check voltage during cranking. It should not go below 10-11v.

Ill do that when im home, what does it tell if voltage drops that low?

Your battery could have high internal resistence.

If it has been damaged yes. But it also narrows down where the resistance in the system could be located.

Found a bad connection on the transmission, car starts perfectly now, drove it 10km and it seems fine so far.
Thanks for the help @swift yoke
