The fuel pressure specification for a 1996 Jeep Grand Cherokee varies depending on the engine. You'll need to consult your owner's manual or a reliable repair manual specific to your Grand Cherokee's engine (e.g., 4.0L inline-6, 5.2L V8, 5.9L V8). These manuals will give you the exact fuel pressure specifications, usually measured in PSI (pounds per square inch).
Without knowing the specific engine, I cannot provide the correct fuel pressure. Attempting to find the pressure without this information could lead to incorrect diagnostics and potential damage.
