Vehicle
Porsche 944
The front-engined, water-cooled transaxle car, and almost nothing about it follows 911 practice — the engine is a large four-cylinder with balance shafts, the gearbox is at the back, and the two are joined by a torque tube. Diagnosis is dominated by one interval: the timing belt and the balance-shaft belts are driven together and the engine is an interference design, so a belt or a failed roller destroys it. Belt tension is a specified measurement, not a judgement. The DME relay is the classic no-start — a single relay feeding both the fuel pump and the injection system, and it fails intermittently with heat. The Turbo adds a boost-control system whose vacuum lines perish and read as a wastegate fault.

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 makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
