Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hi . Thank you for asking your question on JustAnswer.Thank you again for trusting us with your problem. John aka eauto
did you recently run out of gas?
they are fuel pump codes give me a few ill get you some more info...any running issues?
yes i know the codes does it have any running issues or motor noise?
this is somewhat of a common issue with these likely you are experiencing is timing chain stretch. This will affect how the vehicle runs, and will generally make noise. Some early 2011 and 2012 models have a older style chain that stretches. When it does it actually rubs against what infiniti calls a oil jet, or the actual Chain. The oil jet is what sprays oil on the timing chain as it rotates. This is very labor intense job as the oil jet would need to be replaced as well as all the timing chains along with updated gears since the factory gears timing marks are wrong. So the gears are replaced
The Chain drives the high pressure pump Direct injection pump.
