Getting a p1220 on nissan maxima 97...changed out the fpcm and the resistor with a known good one still getting same code...what should i check
-
Next step is to check the FPCM dropping resistor. The resistor should have about 1 ohm resistance.

Ok thank u will do...what resistance numbers should i have at the FPCM itself? Just in case i got a bad one...looked online everywhere ..my Car runs fine...has no starting issues
-
According to the factory service manual, the resistor should be at 0.9 ohm. The factory recommends to replace the resistor if is not at 0.9 ohm.
The part number: 22698 31U02, but it me be discontinue.
I found a used one here: https://www.ebay.com/itm/Ge...
The Infiniti I30 is the same as the Maxima. Ask the seller to measure the resistance before you buy it.

I fixed the issue...the green/red fuel pump wires were grounded out... Mechanic A "mickey mouse" to bypass the fpcm and get direct voltage to the pump.
