Looking for a video or any other available guide to changing the fuel pressure regulator on a 4th gen maxima.

My issue is similar to many other maxima owners issues. If I don't start the car for more than a day it takes a few cranks to start it. As long as I start it every 12-15 hours it starts without issue.

Why would that be caused by the fuel pressure regulator? Is it leaking? To replace it, relieve the fuel pressure and then just remove it. Those two screws will be a challenge.

I don't know for sure that it would be the culprit. Just going by the hunch of a part time mechanic friend.

I had the same problem twice. Once the vaccuum hose was torn. The second time the fuel line going to the FPR was slightly loose causing the fuel rail to very very slowly loose pressure after sitting. There is also a 90 cent o-ring which could be the culprit.

Thanks for the heads up. I'll check those out first.

I don't think a video is needed for this as it is right in front of you as you open the hood. As for ruling this part out, if you crank your car and it starts up and dies right away, then the FPR could be the cause ONLY if you need to keep your foot on the gas to keep it on for a few seconds. If otherwise, your problem is somewhere else.

or it could be the coolant temperature sensor but usually then the starting problem only occurs when it is cold. Check your gas cap too. That keeps the pressure in as well.

If I start it once a day I have no issues. If I let it sit, it takes a few times to get it started.
