Hello everyone 😉 I have a question and a problem at the same time. BMW E39 523i 98rok. I get an error `` fuel tank vent valve '' I replaced it, it turns out that the error is further I will add that it was impossible to adapt what he did not want to start the car 4 times it fired fir (emergency state) question if it does not faint the exchange is where to look for the cause? bundle in cables?

Best way to check is if there is any vacuum leak with smoke test and/or if there is any electrical issue that will prevent from it to start. Also my guess is your fuel pump is gone

[@ukaszmarciniak5479]

@@buddhizibi there is no fuel pump do you mean? no, no fuel pump;) it works mechanically after removing the fuel tank vent valve. The resistance is 48 (Ω) on this valve, the question may be, you need to measure the plug, does it have electricity?

@@ukaszmarciniak5479 i do not think vent valve connection would cause no start. what codes do you have? do you have fuel in your rail?

[@patienceisalifesaver9582]

Can this cause vehicle not to start ?

[@greenman7612]

No. It’s a pollution control issue.

[@dominikspencer3981]

Actually, YES! A faulty purge valve that is stuck open will cause a Too Rich stoichiometric mixture by letting too much gas vapors into the combustion chamber. This can, or will, cause start issues....
