Should be 40-45 PSI. What are your readings?

Thank you. Got 45. Have a stalling problem though it might be fuel pump. Already did full tune up. Just tested fuel pressure regulator with no help there. Put a scanner on it for second time and it now shows knock sensor is out of wack. So here I go again. Thanks for the info.

Nissan had problems with a corroded connector on top of the fuel sending unit. The terminals would turn green and eventually the pump would stop. You can access the sending unit from under the rear seat to check for corrosion on the two-pin plug.

There is actually a recall on the fuel sending unit but you need to check your vin to make sure your vehicle applys. I had this problem on mine. It was an early 2000. The connector corroded inside and I didnt even see it unitl i went to plug in the new sending unit. (I bought a new one thinking it went bad and wasnt covered) It was only $80 so I wasnt too mad about it.

Thanks all but turned out to be mass air flow sensor and never showed a code for it. Friend of mine caught it. Whew!
