Hey guys, just picked my 2010 Nox up from the dealership, after only 42,000km the fuel pump started to fail. I was starting to have a bad case of run on after stopping the engine and they traced it back to the fuel pump. Anybody else had something similar happen? I'm just wondering if this is a freak instance or not. Its a 2010 Nox LTX fwd 2.4L.
It started with a check engine light about 2 weeks ago, shop couldn't get it in until a few days ago. It was originally just a check engine light, onstar diagnostics reported a fuel system error. During that two weeks the check engine light came on and off a few times, service stabilitrak came on once, and closer to the end it started running a bit rough. When idling there was a rough vibration, and thats when the run-on started when I would kill the engine.
New fuel pump and mass air flow sensor. I have my doubts that running on a bad mass air flow sensor for two weeks would have killed the fuel pump, but is it possible?
