Key on, engine not running: 53-55 p.s.i....
take the plastic cover off and you'll fin it under the throttle body
u dont it does it by itself just put it in the area of fuel and boom a pressure regulator
Could be the Fuel Pressure Regulator
The fuel pump pressure for a 1996 Pontiac Bonneville should typically be between 41 to 47 psi (pounds per square inch) when the engine is running. It's important to check this pressure with a fuel pressure gauge to ensure proper fuel delivery and engine performance. If the pressure falls outside this range, it may indicate a problem with the fuel pump, filter, or fuel pressure regulator. Always refer to the vehicle's service manual for the most accurate specifications.
The fuel tank pressure sensor is actually the fuel pressure regulator. There is a sensing unit within the regulator.
This was originally my question. It ended up being the fuel pressure regulator.
Could be the fuel pump, fuel pump relay or fuse
41-47 psi
Fuel Pressure Regulator - would do that -
The fuel pressure for a 2000 Pontiac Bonneville typically ranges from 40 to 50 psi (pounds per square inch) when the engine is running. It's important to check this pressure using a fuel pressure gauge to ensure proper fuel delivery and engine performance. If the pressure is outside this range, it may indicate a problem with the fuel pump, filter, or pressure regulator. Always refer to the vehicle's service manual for the most accurate specifications.
That's going to be on the fuel rail at the intake manifold
