I changed the cam sensor but still doesn't start. Any ideas?

Thanks for the reply! Will order a new cam sensor and report back. If anyone has other suggestions, please let me know - Thanks!

Thanks for the reply! Then is it possible to have a broken cam sensor but no code? No, did not change the lamda sensor, could a bad lamda sensor cause this?

Hello I am having trouble with a 1994 Audi 80 Avant with the ABC engine. The engine shut off while driving and has not started again (battery fine and a strong crank), I have read the engine with a VAG computer and it gave 518 (G69) Throttle position sensor (sporadic - short circuit to earth) and 555 G108 Oxygen (lamda) Sensor (sporadic - impulsible signal.) I installed new original Throttle position sensor and cleared the codes. The codes are now gone even after a lot of starts an no codes to read now. There is fuel in the fuel rail, spark from the spark plugs and 10 volts at the injectors. I hear the fuel pump (I change it after the car died just in case) and have also jumped the fuel pump relay. Seem to be some sensor or computer error I think but as I said no codes now from the engine. Does anyone have any suggestions on what might be wrong and if it is possible that it is the camshaft sensor without code? I had the same problem (no start when cranked) maybe 8 years ago but then the engine gave a code for the camshaft sensor and that did the job.
