does it re-start easily after a short drive?king_wrecks wrote:Hey guys and gals, it’s been awhile since I’ve been around but I still have my Pathfinder and lately it’s been getting on my nerves.
I’ve owned my Pathfinder since 2011. Every time I turned the key, it starts RIGHT AWAY. No idle issues, ran perfectly with 16-19mpg depending on driving conditions. A few months ago I hopped in and bumped the key and it turned over but didn’t crank. I turned it back off and then held the key for about 5 seconds and it cranked but all the lights on my dash came on and went back off except the “SERVICE ENGINE SOON†and “VDC†lights. Since then, it takes a few seconds before it starts and while driving, it seems as though there’s a surge when coming to a stop. I haven’t driven out a full tank in awhile so I’m unsure of fuel mileage.
Anyone have any ideas?[/b]
R51's in the USA don't have a serviceable fuel filter; it's part of the fuel pump module inside the gas tank.Graham W wrote:Might sound daft but have you tried a new fuel filter ?
Just read about the fuel getting low when it was cold,
maybe, just maybe the pump dragged a load of crap from
the bottom of your tank which now lives in the filter blocking some fuel flow?
I’m a stickler for changing mine at least every 5000 or less if I think it’s getting sluggish. My old shogun used to throw codes up and a mechanic nearly put a new fuel pump in, but some one more on the hammer swapped the filter and told me to rag her home to clear the pipes.
It worked and I swapped the filter more than needed to keep the crap at bay, engine bay lol
Crank position sensor isn't too bad to replace. You have to remove the right-front wheel and the plastic wheel well liner (you may want to get some new, 10MM push clips because the old ones have a tendency to break when you take them off). Once the liner is out of the way you can see the crank position sensor. It's held in with a single, 10MM head bolt. They are also a lot cheaper than the crank position sensor. I think a genuine Nissan part is around $35 if I'm not mistaken. Get the code read!!king_wrecks wrote:The battery isn’t very old but I haven’t checked/cleaned the posts. In the original post I failed to mention the issue started with a nearly empty tank when the weather was at or below freezing. As for repetition, it pretty much does it every time I start it. Also, I had recently burped the coolant system and was almost a gallon low.
As for crank position sensor, how invasive is that repair? Basic hand tools and a Haynes Manual?
Someone with a Murano told me I should check the fuel dampener. Anyone have any experience changing one of those?
