Around 40-45 PSI, it varies from car to car.

My 2000 Nissan maxima wont rev above 2RMP.


Have you inspected the catalytic converter for blockage? The other issue could be fuel pressure...the fuel regulator could be defective. Hope this helps.

I have a 1990 Nissan maxima that has been leaking a dark brown fluid on the rear driver side. It smells like gas when u walk up on it but had it checked for leaks and mechanic said there were no gas leaks....


your maxima is a front wheel drive. a torn boot would leak grease,and it would be in the front.
the leak could be old gas with rust in it... take it in and pressure test the fuel system,also check the fuel filter.,especially if the car cranks for a few seconds before starting some times ,that means there is a pressure drop..

I have a 1990 nissan maxima, and it won't start. I've had the battery, alternator, and starter checked and they are all ok. What would be another reason why the car won't start?


If there is no "clicking sound" you may want to check the starter relay if it is still working. You can have it tested if there is voltage running to its terminal. Also check the ground that connects the engine to the body of the car. You may have loose connections. If the starter motor turns you may want to check if there is fuel running to your engine. You may have a bad fuel pump or fuel filter.

Fuel Pressue 1987 Nissan maxima


1st I hope you are taking the fuel pressure from the correct side of the system. The correct side will be the side coming from the fuel filter and before the fuel pressure regulator. At a normal idle, the pressure should be roughly 30-33 psi. When you crack the throttle rapidly, a sudden vacuum drop will cause the diaphragm in the fuel pressure regulator to shift causing the fuel pressure to jump sharply. Usually to 45 or 50 psi. You can check the maximum fuel pressure by dead heading the pump. This can be done by simply pinching off the return hose to the fuel tank. At an idle, the maximum fuel pressure the pump will put out will be displayed. You will also notice a slight jump in rpm's because it cause the fuel mixture to fatten up before the ECM can respond to changing the pulse width based off of the o2 sensor.
I hope my answer was satisfactory.
