Where is the fuel pressure test port?

[SBS]

Hi,

I've been having trouble with my fuel pump. I just replaced it and now I get engine stubling and code 0300 (random misfires). I want to check my fuel pressure but I can't find the fuel pressure test port.

The vehicle is a 2001 Pontiac Grand Am 4 Cylinder.

Where is the fuel pressure test port?

Thanks,
Sal

According to my haynes manual, it says that it is near the front right corner of the cylinder head. The picture shows a cap that looks like a cap from a bicycle wheel stud and right above the radiator hose. Assuming you have a 2.2L because that is what the picture is describing.

Thanks..

Mine is a 2.4 L engine... I checked where you said and I don't see the port. It really looks like this one doesn't have it... which would be strange.

Anyone out there with a 2.4 L engine?

Thanks,
Sal

I see now. 2.4L models dont have a port. You must have a special adapter hose and install it on the fuel system piping, once again coming from my haynes manual. This time I'm sure again. Haha. Sorry.
