i had an issue where i drove my 2000 audi s4 b5 parked it and 4 hours later went to start and it would not start just cranking and cranking i put a code reader on and pulled 2 codes p1392 and p1338 they are camshaft sensors replaced both and cleared codes tried starting and both codes came back with no starting just crank I’ve seen some posts about this but no definitive answers on what to do can anyone help !?

So I ended up checking for spark and it had good spark so I then did a compression test and it made nothing so I’m pretty positive it jumped timing but if it jumped while turning it off is it possible I didn’t bend a valve ?

1. Were you close to TB change interval (Cars make nuff torque this when it usually jumps)
2. Pull valve covers and check tension/slack on chain. move crank to timing mark chains have a mark
and should line up. If not theres your compression loss. (Had a shop tell me same thing when I checked tensioner on PS side had failed)
3. Minus compression loss Check ECU and Fuel
4. Check the ECU fuse if your car doesn’t have one swap ECU’s you may have blew a module.
