I will post an update on my car when I change the aftermarket pump out with an oem one it’s either that or my timing job is slightly off the car only acts up at idle
Thanks for the input, much appreciated. My in laws had their Verano blow the engine due to timing chains let go while driving, when I was swapping out the engine id noticed the fuel pump wasnt included with the used engine for some reason, and I didnt trust the one on the blown engine. Bought an aftermarket one from what I was told was a good company, and a few months after they've gotten the car back, these codes have come up. Ive driven it extensively and only seems to act up at a stop light.
