The fuel pressure for a 1994 Chevy S-10 Blazer will vary slightly depending on the engine. You'll need to consult your owner's manual or a reliable repair manual specific to your vehicle's engine (e.g., 4.3L V6, 2.8L V6, etc.) for the precise specification.
However, a general range for many GM vehicles of that era is between 35 and 45 PSI. This is just a guideline. Always refer to your vehicle's documentation for the exact fuel pressure. Using the incorrect pressure can damage your fuel system.
