I just want to know what the correct fuel pump pressure for this car should be.
It's a GA16DNE engine.
Also, could you send a photo or direct me to where i can see it of how the fuel pump module/housing should look?
Thanks

Hello,

At the engine idling the fuel pressure should be 34 PSI with vacuum hose connected and 43 PSI with the vacuum hose disconnected

You will need to use a fuel pressure test gauge to check the fuel pressure. The gauge will need to be installed after the fuel filter under the hood.
See attached procedure for checking the fuel pressure. Also included are the fuel pump diagrams as well. The pump can be accessed by removing the rear seat.

Let me know of any questions.
Thank you.
