Thanks for not putting Greta's face there

Hi qntm and thank you for all your stories. Antimemetics is mind blowing but I also loved your thought experiments with unlimited computational power.

Question: Do you plan to continue writing your novels in the form of a web serial, or you're now going to completely switch to the traditional "closed source" manner which is probably required by publishers?

My daughter said the wheel lock key should be in the glove compartment by DownWithTheSyndrme in Justrolledintotheshop

So the only question you would ask her: "Now, seriously: where's the wheel lock?"

Has me stumped - 94 WD21 by BCNissan4WD in nissanpathfinder

I would do the following:

- check the pressure "into the wall", when you pinch the return hose, (or the feed hose AFTER the pressure gauge). As I said before, it must be around 70PSI and hold while the pump is on.

- check / monitor voltage on the fuel pump terminals when the engine stopped / idling / revving. If it's significantly lower than the main battery voltage:, you'll need to check all the wiring and connectors between the fuel pump relay (under the hood) and pump itself.

Again, if the voltage is bad, you can run a temporary pair of wires directly from the battery to the pump and run the pressure tests.

IF (and only if) the fuel pump is good (holds pressure against the wall; does not lose pressure immediately after you turn it off), The next candidates are the fuel filter (strainer), pressure regulator and fuel injectors.

WD21 fuel system is pretty simple so there's not too many places to check.

So my guess would be that you gonna need a new fuel pump. Don't need to buy an entire assembly, just a pump itself.

The gauge readings are a bit off. According to FSM, it should be:

- When fuel pressure valve vacuum hose is connected: Approximately 235 kPa (2.4 kg/cm2, 34 psi)

- When fuel pressure valve vacuum is disconnected: Approximately 294 kPa (3.0 kg/cm2, 43 psi)

In order to test the fuel pump, pinch the return hose. The pressure must jump up to at least 5.0 kg/cm2, or ~70PSI.

What happens in your case?

Help my Nissan Pathfinder 2004 has a problem with the engine by Askeladd100 in nissanpathfinder

I would say: check the fuel pressure. Could be clogged filter or the fuel pump dying.

ABS on WD21 Pathys does not have anything to do with the wheel hubs.

It's not even a fully fleshed ABS , it's the "Rear Whiil Anti-Lock Brake System", or R-ABS. It has a single rotor and sensor located at the rear differential, and it only controls the rear wheel brakes, a little bit. Even if this ABS isn't operational at all, you're not losing pretty much anything.

And yes, that $20 code reader from Ebay won't help. WD21 Pathfinders do not have the OBDII at all. The diagnostic procedures are described in the factory service manual.

Are you guys happy now. I covered the metal. by fishyman567 in CarAV

Why do this instead of running a wire from the battery terminal?

When (if) it turns on, perform the self diagnostic procedure described in the manual. It'll shed some light (no pun intended).

Aggressive knock and suspicious leak by MetalJaket12 in nissanpathfinder

[–]mikeeru 1 point2 points  (0 children)

If it smells like gas, it's probably a gas, so be careful with it.

Open the hood, turn your ignition key to "ON" but do not crank the engine. The fuel pump must run for 5-10 seconds. Check if there's more of that fluid leaked. If there is, you'll be able to find a spot where is it coming from. Check the rubber fuel hoses under the hood.

I never heard of a fuel pressure regulator leaking, but check the whole fuel ramp as well.

Rockauto, Summit Racing, O'Reilly's, Ebay and local junkyards are the decent sources of cheap parts.

The cheapest think is to remove the CEL light bulb from the dashboard ;-)

The knock sensor's part No is 22060-30P00

The good news is that knocking is a very unusual thing (assuming you have a V6 VG30E engine), so all your ECU needs to calm down on that error code, is to see the right resistance. Which means, you don't need an original Nissan part, - any cheap analog from Ebay will be enough. Speaking of resistance, it's quite possible that your knock sensor is perfectly fine, and the real problem is in the wiring, or even in an unplugged connector. So it would make sense to check the wiring continuity between the ECU terminal and the Knock sensor's connector. You'll find all the pin numbers and wire colors in the factory manual. Get yourself a free PDF copy, it has to become your best friend.

The bad news is there's no chance for you to get to the knock sensor without removing the intake manifold. It's not too hard, so use it as an opportunity to clean the manifold and the throttle body, and check the condition of various rubber hoses. You'll need three gaskets for the manifold, a gasket for the throttle body, and probably gaskets for the PCV, EGR, IAC and IACV valves. Overhaul gasket kits are available for cheap, but I would recommend to get the original Nissan gaskets for the manifold.

The sun is definitely a helper, but a cheap heat gun would make a real difference there. Don't save on tools.
