BMW 520i/525i Engine wont run properly

[ot12345]

hi, i have a bmw 520i with a 525i 12v engine 89model, whene i start the engine it runs only on a few of the cylinders and after a while it stops and i cant get it running again..

ive done a diagnostic on it an it said the following

16-impulsengeber der kurbenwelle
17-impulsengeber der nockenwelle

ive changed one of the sensors and it stil wont run properly, and i cant find the second sensor, the one on the crankshaft (or there isnt a sensor there?)


please help, ive tried everything

Has the ignition system been checked/replaced as needed?

[ot12345]

Ive changed everything from the coil to the sparkpluggs, the fuelpump is working to, so i think it something elektronic?

[witeshark]

How about the distributor and the wires?
