The fuel pump completly died and I had actually to replace it. Heres some of the trouble shooting i went through.For reference, below are the prices of several of the parts:17040-9EG0B Fuel Pump Assembly $34017342-EM30A Packing-Fuel Guage (big O-ring because that the fuel pump assembly) $37 (not required, your choice if you require or not)22670-ZR70C Fuel pressure Regulator $28 (included on new fuel pump assembly) 284B7-EM33A IPDM (the relay and fuse box) $300The fuel pump, pressure regulator and also IPDM space all well-known to it is in issues, the pump and also regulator much more so. Check out this thread for info on push regulator organization bulletin.What occurred to united state was that the car died. Top top trying to restart, that would get a cylinder fire here and also there, but the much more we make the efforts to start the less frequent it would happen until after around 6 tries beginning it simply wouldn"t perform anything. Therefore this led me to think that over there was part fuel in the heat at first, however as ns tried to start it the fuel ultimately ran out.I checked to make sure the fuel pump was priming once you very first turn the an essential (but don"t try to begin it). But this is whereby I got tricked. There is other in the engine bay the also primes when you an initial turn the vital on. You need to actually get down close to the fuel pump to verify.To gain to the fuel pump, simply yank the behind seat up. It has clips that hold it to the base. Press all the seat belt latches with the holes. You will should unbolt the middle lap belt and feed it v the hole.
Once you have the center belt free, a trick I perform with seat belts is to placed a zip tie about them near the retractor. This means the belt doesn"t completely retract and also then you have to fight the auto lock.
I additionally took this oppurtunity to to wash the behind seat base since they had actually some son stains on them and was cost-free from the car. I simply used a water hose, laundry detergant and also a plastic bristle brush. The seats dried after about 2 days and also stains were gone.You should now see the fuel pump cover. Just twist the 3 plastic locks and also the cover will certainly be free.
Now you can listen to see if the primes. Friend can likewise test the its actually pushing fuel out. To acquire the fuel heat off, press the tabs on the small white plastic seal and also pull the black color hose component back. Ns hooked a piece of hose to the outlet that the fuel pump and also then stuck the line into a water bottle. Revolve the key on and also see if any fuel comes out. The fuel pump only pumps because that a 2nd so you won"t unload your fuel tank into the water bottle. Be certain to placed some rags under there incase the line is pressurized (it need to in normal situation). And also make certain your in a well ventilated area (garage door open).
If you have a little bit of pressure, climate you could have a negative pressure regulator. The is top top the fuel pump and also the fuel pump will should be removed. See more down on exactly how to execute that.If the fuel pump doesn"t prime then you have actually either an issue with the IPDM, the wire harness or the fuel pump.The IPDM (Intelligent Power circulation Module) is situated in the engine bay. That is a level black thing in the driver side fender well by the battery. It has 4 clips. You traction the "lid" off and also turn it end to view all the fuses and also relays. For part lovely factor the owners hands-on makes no cite of this module, yet it has actually the fuses in it that space most most likely to leaving you stranded. Verify i beg your pardon version/shape IPDM friend have.There is a fuse that can be inspected. The fuses are labeled top top the under next of the IPDM cover. The relays space not labeled, yet it doesn"t matter. There is a fuel pump relay in the IPDM, however it is internal and not user servicable. Due to the fact that the fuel pump and also IPDM space both expensive us don"t want to guess. So very first trouble shooting the IPDM. Verify the fuse because that the fuel pump is ok. Depending on which design you have actually locate pins 1 and also 36, these are the 2 us will treatment about. Pen 36 is brown colored and also indicated by the IPMD schematic. Usage a multimeter v sharp points on the leads and also stick the black lead versus some bare steel on the auto (I used the battery tray). Then stick the red lead inside the cable harness. You desire to cram the needle component of the lead alongside the wire so that way the lead is touching the steel pin up inside the harness. Pole the multimeter up on the cowl (in prior of the windshield). Set it DC mode and turn the key, however don"t try to start it. Pen 1 should have actually a constant 11-12 volts. Next examine pin 36, you need to see the multimeter run to 11-12 volts for just a 2nd and then quickly start going down. This is the voltage used to prime the fuel line, it simply turns the pump on because that a second.
If the IPDM pass inspection climate next move to the exploit at the fuel pump. The exact same brown wire is what has actually the voltage. Stick your multimeter red lead right into the exploit pin, and also the black versus some metal suggest around the fuel pump cover (or usage the object from where you took the end the seat belt). This is whereby my check ended. Had actually the quick 12V burst in ~ the harness. So the fuel pump was now the end of the line. Replaced fuel pump and car started best up.
To obtain the fuel pump out you need to rent a tool from Autozone. Don"t shot to use a hammer and screwdriver or chisel. You will require WAY much more leverage then that. You can stick a cap over nipple simply to save the fumes and loose fuel come a minimum. Oh and also your fuel pump will more than likely be filthy. This access port opens up to outside, mine was filthy. This is after ~ some heavy windex and rags. I beg your pardon I would certainly recommend when working around the fuel pump just to store particles from gaining in the fuel tank.

The tool to rental from autozone is component number 27160, called "Fuel Pump replacement Kit". The $90 to rent it, which friend get completely refunded as soon as you return it. Usage the tool circled in yellow. Adjust the metal legs come push versus a tab on every side. The square feet in the optimal bar is because that a 3/8" socket wrench. We used a 2 foot lengthy 1/2" breaker bar with a 3/8" adaptor and also it took some incredible force to acquire the lock ring off. We finished up bending most of the tabs, and then just straightened them the end afterwards. Going back on friend won"t bend anything together you will be pushing on the back of the tabs which are stronger.
Hope this is helpfull is fixing your item of crap Versa. 3 years old through 83K miles and brand-new engine and also fuel pump already.
