The fuel pressure for a 2003 Chrysler PT Cruiser varies slightly depending on the engine. You'll need to consult your owner's manual or a reliable repair manual specific to your PT Cruiser's engine (2.0L or 2.4L). These manuals will give you the exact specification for fuel pressure at a specific engine speed and operating condition (e.g., idle, key-on-engine-off).
Do not rely on a general answer found online. Incorrect fuel pressure can damage your engine. Always use the manufacturer's specifications.
