02 - 5th gen Maxima - starts but won't stay running. it will only idle barely for about 10 secs and die and will not respond to throttle. No codes.

Because I could not test the fuel pressure and went on a hunch and got a pump and strainer. They did not have the filter assy. I put that in and it did not change. I am going to get a Nissan filter from CP as they are cheap. It had a lot of small debris coming out of it when I was assembling but I do not think that alone would cause the problem I have.

I was able to jury rig a pressure guage on the pump outlet and got 43 psi but I would rather have connected that with a t connection in running condition. I don't know why Nissan didn't have a connector.

Am I chasing the wrong thing here? I also clean the MAF sensor. I still think its fuel related.

will this adapter work on pressure rail ?

I just unplugged MAF and now it will idle and run up to 2200rpm.

I found info on this thread

ok since now you know its a MAF problem you will notice that MAF sensors for a 2002 are maddd expensive. well don't worry there is a solution. do not ever buy a aftermarket MAF sensor because you will waste your money, happened to me 2 times. you gotta get a original nissan maf sensor but a 2002 sensor is like $442. so you gotta get the maf sensor for a 2000-2001 maxima, its like $90. i think this is the sensor i found it on courtesyparts.com

im pretty sure thats the sensor, and once you get this sensor you uninstall yours and you transfer over a little thermistor thing from the old sensor onto your new sensor and your good to go. look on the org there is a whole post about this and how to do it. save yourself the money and get the right part you will be happy.

I had already ordered the aftermarket MAF sensor from Ebay and just got it and plugged in and it seems to run ok. What will happen now ? The aftermarket had no thermistor

Swap over the therm from your old maf and solder it in place they hardly ever go bad

paradiddle

what does the thermistor do ? and I take it it's not ok to run without it.

paradiddle

The ebay seller responded that it did not need a thermistor. But I already soldered the old one on the new one. I may take it back off per seller instructions and see what happens. Its running good again.......

I think I have had 2 bad ebay MAF sensors and now it's time to getthe one you suggested. !!

Does it matter if my maxima is a 3.5l not a 3.0 for this to work, using a 2001 MAF on my 2002?

My 19$ EBAY MAF lasted about 4 months and just **** on me this am at 5:20am, so spending the 90$ and soldering thermo is worth it.
