Nissan Frontier XTerra 2.4L | Fuel Pressure Regulator | 1998 - 2004 | No Start After Engine is Hot

So after driving the Nissan and getting it hot, letting it sit for 20 minutes it had a hard time starting. Effects Frontier and Xterra Nissan models, with the 2.4L 4 cylinder engine. Here is a good description of whats happening from a Nissan forum. I will put the link down below as well. Ended up changing the FPR fixed the problem.
I was trying to fix a problem I was having starting my 01 QX4. After sitting for extended periods (a few hours or overnight) it would take a few extra cranks and then there would be an uncomfortable hesitation and it would reluctantly start. During the hesitation, there would sometimes be a knock or two, like when an engine is running out of gas (you know the sound if you've ever blown or pulled the fuel pump fuse and tried starting it). I did some research on this forum and elsewhere, and kept hearing the hint that it may be the fuel pressure regulator. The problem is that when they go bad, the regulators allow too much fuel in and leaks back when the engine's at rest (caused by a bad seal or it hanging open).
1. Blackened spark plugs - This happens when the engine is running too rich, which is what happens if the regulator is giving the engine too much fuel. I changed the plugs when I got the car about a year and a half ago and saw the carbon, but didn't think much of it. I figured they had never just been replaced.
2. Engine doesn't run smoothly - This wasn't a problem for me at all except at a warm idle, when it would shake and quiver randomly ever so slightly, like a cold rabbit. Other than that, takeoff, acceleration, and deceleration had no noticeable problem.
3. Black smoke out tailpipe - I never noticed this, so it wasn't severe if it was the case. I did notice on cold days that the exhaust steam did seem to be much more plentiful than other cars, though.
4. Dipstick smells like gas - This and #7 were the clinchers. There was a definite smell of gas in the oil vs. fresh oil.
5. Gasoline dripping out of tailpipe - Never noticed this, but never really looked.
6. Stall on acceleration - See #2; not a problem here.
7. Gasoline in the vacuum hose - I didn't see any dripping out of the hose, but it reeked of gas.

Nice, I miss working on older vehicles. I replaced a fuel pressure regulator on my 06 Focus when the fuel pump died. I did that mostly because I didn't know how long the pump had been going bad and how much the regulator was trying to make up for it.

I can say this does work. I replaced it on my 00 Acura TL two days ago and stalling no start went away! Thank you for the video.

[@bundysgarage]

Glad this worked for you!

[@IvanLopez-jv2dm]

Thanks for the video… it solve my problem!!!!!

[@soponsuree9352]

Great tip. I’ve been having the same issue with my ‘99 ml320

[@texson5378]

If you put a little valve grinding compound on the tip of the Philips, it will bite in the screw head much better. Then for sure replace with bolts!

[@jcalzada74]

I learn my lesson, when I replace the a injector from my nissan I stripped the philips head i replace all of them for 10mm bolts included the fuel regulator

[@coreymills1520]

You might also have success using a pick next time with those fuel line hoses

[@1turntmigo]

Did you get a code before you fixed it ?

[@bundysgarage]

No code.

[@coreymills1520]

Next time take the fuel pressure regulator off of the engine then pull the fuse hose off otherwise you could run the risk of breaking the screws off or dropping the screws and the engine
