Micra K11 Fuel pump

Postby wayner6708 » Tue Jul 29, 2014 5:33 pm

Hi Everyone,
Just joined this forum and have had my 2 channel pico for a few weeks now.
My Nissan Micra K11 has a lean condition at idle with fault code po170.
The MAF , o2 sensor both check out ok and there are no vacuum leaks. I think it could be the fuel pump.
Can anyone tell me if this is a good waveform or not ?

Cheers.

Electrically, the fuel pump does not have anything, but we need to see mechanically, or a problem with the pressure regulator, to be sure, you can check the fuel pressure and flow. :D

Fuel pump is turning 7816 rpm is this a little high or is this normal? I thought it should be a little lower.
