omega b doesn’t start after ripping of the belt

yes I know … the good search function etc … 😉 but in this I did not find a threat for my problem … here my problem : I was torn on the highway of the belt (renewed 3 months ago ) and the engine went out … then I rolled off the highway and came to a parking place. the next day new belt brought up and raised. so far nice and good but then the good didn’t jump any more … after blinking out the error code came the following messages 0130 – voltage of the circuit of the lambda sonde as well as 0340 – voltage of the hall sensor NWS (by siemens) changed – still nix. additionally the error message : 0335 false signal for the motor speed to attract / push has brought nix … causer turns (slowly) … spark of ignition is present and ignition candle was wet/wet below when I took it out. relays of the injection and the gasoline pump replaced. (are identical) also nothing ! ECU ?? have Irge andwhat of “reprogramming” read if you had such problems ?? markings on the wheels of the camshaft also agree. the question is: where does the marking of the crankshaft have to stand then or what does the marking look like ?? are the 2 recesses outside on the wheel of the crankshaft ?? if yes where do they have to stand ?? have heard so on “1 clock” ?? besides I noticed when I turned the crankshaft by hand that it has hooked after a twist and I didn’t use it Is it possible that this is the reason why the belt is already torn 2 times ? can all this be related or is it possibly just a stupid coincidence ?? especially … what can I still do ?? KWS on suspected change ?? would like to avoid since I have it straight “not so thick” … I hope you can help me because I am really forgiven ! gruss marco ps : j a the car has sprit (I was actually asked in another forum)
