Fuel pressure
So I checked the fuel pressure on my Schlader valve or whatever the damn things called , and it reads 38psi with ignition on, engine off. Car manual says it's supposed to read at 40 with ignition on and engine off, and with engine on its supposed to go down 3-10 psi. Like wise when I turn the engine on it'd drop down to 28, and if I rev the engine the pressure only goes up about 1 or 2, (to about 29-30) for a quick second and then drops right back down to 28 even if I'm still on the gas pedal Revving. So my question is, could this 2 psi difference mean I have a bad fuel pump , or what ?
