So I noticed after fueling my is won't start. It will turn over, but wont start. After the fourth or fifth time it will start. I got the check engine light on and got p0174 and p1170 codes, there are several pending codes p0303, p0171, p0174, p0441, and p1170. I have 148K on the 2014 IS350. I have changed the maf and purge valve. I don't think it's the fuel pump, because it will only happen after I put gas in. Other than that the car idles good and nothing is wrong. I have cleared the codes and the check engine light hasn't came back on but after putting gas it will not start. It will turn over.
