It could be the canister but I would mark a code, I lean more for fuel pressure sensor and gasoline pump problem, it is not necessary to check injector rail
First of all, thank you very much for your time. I have little I have this vehicle but I like it, the admission control and sensors go by empty I changed a tube that was cracked I have to control them all to see if there is any strangulated.Chrobare what you tell me (although of media I am short) I will also check the TPS and the empty sensors to see if there is luck.
