Cause
Faulty injection pressure regulator
The valve setting high-pressure oil for the injectors. Too little pressure and the injectors never reach their firing threshold, so the engine cranks normally, has fuel and spark, and simply does not start — which sends people to the fuel system every time.
Typically a moderate job.
Some of these codes mean you should stop driving
2 of the 9 codes this can cause indicate a fault where continuing to drive risks damage or is unsafe. Which one you have matters more than the cause does — read the code's own page before deciding.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
