2002 vw passat 1.8 timing

Well I'm having what I believe is a timing issue on my car. My dad was using my car and the radiator busted which then ripped a hole in the radiator then lost all the antifreeze but he kept still driving it unaware of the problem until last minute which ended up blowing the head gasket. As of yesterday I got the new head and head gasket installed along with a new timing belt kit with the metal impeller water pump not that plastic shit. Now to the problem. The problem I'm having is the car will not start until the second to fourth attempt. Once it starts it run with no problem beside throwing a p0341 Camshaft Position Sensor "A" Circuit Range/Performance. I never had this code before until I got the car back together. I thought maybe the Camshaft sensor was going out so I robbed one off of my other passat and it's still throwing that code. I believe it's timing related but my problem is where in the hell is the crankshaft timing mark I found it on the harmonic balancer but I can't find it anywhere on the engine.
