I have a 1995 nissan pathfinder.
the engine run greats dosent burn anything or leak but when the key is on or truck is running i hear the fuel pump hiss. I also get horrible gas mileage i get 11.6miles to a gallon. that dosent seem right for a 3.06 when my buddy has a 4.0jeep and he gets about 300miles to a tank wile i get under 200.
what could my problem be?

thanks,
Matt

Just took my 95 to the shop yesterday, it shut off going down the highway...i think it was the fuel pump.
i hear a hiss in the back too.....i get bad gas mileage...getting worse every year...
.i would suggest you get plugs checked..and use high octane gas every other fill up...you will notice a little better gas mileage. 16 gallon tank paying an extra 25 cents for 92 octane adds up to about 4 dollars more per fill but if your squeezin 1 to 2 extra miles out of that tank per gallon..it adds up to 4 dollars for 16 to 32 extra miles.
I would not trade my pathfinder for anything, but unfortuntely the frame and body are not going to make it as long as the motor.

I was hoping that you would get an answer to this question since I too have the same issue. I get poor gas mileage. Filling up my 16 gallon tank, I get only 230 miles out of it (till empty, if I'm lucky), which is about 14mpg. And now as I write, the engine isn't even getting enough gas due to a fuel filter or pump problem, but that's another issue.

I have a 95 pathfinder with 120,000 on it. I am not sure if it is the fuel pump. On top of getting low MPG lately, I could not fill as much gas as before at the same gauge level. Very strange.

I have a 95 Pathfinder. I love it...I drive it everywhere. And I pay for it. I have 33 in. mud tires on it for hunting. My fuel pump also hissed and one day my vehicle just shut off. I had it replaced and gas mileage didnt aprrove and the new pump still hisses. It might take alot of gas but I will drive it until it decides its had enough.

I used to consistantly get 19 to 20 mpg on my '95 Pathy. Then it gradually dropped to about 15 mpg. I notice for some time that the metal sheeting around the gas tank had a large oily spot. I dropped the sheeting and scrapped all the oil gunk off the tank and saw two spots on the botton of the gas tank that looked like factory spot welds! These two spots had gas oozing out. I purchased some Quiksteel glue at WalMart and applied it over the weld spots. It stopped the leaks and my gas mileage has gone back up to 19 to 20 mpg. this is my experiece with poor mpg, hope it helps you.

When I got my 95 Pathfinder(about 3 months ago) I was lucky to get 13MPG going down hill with a tailwind. First improvment came with a new airfilter, and a new set of NGK Irridium sparkplugs. Went up to 17.2MPG. I just installed a Cold Air Intake and have plans to install a Magnaflow Catalytic Converter & new Oxygen sensors.I hope to be getting over 20MPG. I have the SE V6 with 4wd,and big tires inflated to factory spec 26psi. Pathfinder engine is STRONG with over 156000 miles & dosn't burn or leak oil, gotta try to keep it...IT'S PAID FOR! I'll post the results of the above mentioned MODS. The Check engine light is NOT on yet but Good(and Clean) O2 sensors are Vital to better MPG..I also make it a point to maintain proper tire PSI, check it once a week or get nitrogen inflated, bad tire pressure is like ankle wieghts in a marathon.DO NOT OVER INFLATE! Rolls best at proper psi! Good Luck!

my problem is my pathfinder i find is mainly my fuelpumps filter clogs up way way way to much, every few days we remove it and its got some blue gunk bult up on it, plugging the filter, weve cleaned the tank, and several times cleaned the filter, but it just keps happening, the vehicle runs fine after we clean the gunk off, but it just builds up again.

My 95 pathfinder just shut down while cruisin' down the highway. A mechanic tells me the pump is going, do they just go/ or do they slowly die, never had any fuel issues, he says it blew the fuse? Could this be? wants to put a new pump in and I can't afford it, otherwise ran great, what fuse? It has about 150,000 miles on it and rusted frame
here and there. Any suggestions? He will put a new fuse in but won't guarantee it will last long.

I have an 87 Pathfinder with about 275000 miles. When I start it it will run for a bit then shut down like it is starving for gas. Based upon what I am reading in this forum the odds are good it is the fuel pump. My question is "where is the fuel pump located?". We like the vehicle so much my wife has an 03, we like Nissan enough to have 2 Versa's as well. We would much rather fix the 87 than replace it. Any assistance would be appreciated.

I have a 94 pathfinder and the battery went low. I disconnected the power cable and charged the battery. When I tried to start it, it just turned over. The battery was fully charged but the engine would not start. I am thinking it is the fuel pump but would like to know if there is anything else I should check. It has the 3.8 liter.

you can get access to fuel pump by lifting up the carpet in the very back....there is an access panel that can be removed and has rooom to replace fuel pump without dropping the tank.....if it does not,,, use drill and small recipricating saw to make one just dont cut the lines or wires.......most 87-95 paths will have bad fuel filters and bad filters on the fuel pump which will eventually make the pump weak, starving it for gas when you first take off....i suggest replacing fuel filter and spark plugs first...then fuel pump....you will know when you take the filter off if the gas is black on the output side and clear on the input side......have had 3 pathfinders and worked on over 10......

I have the same gas problem. i just dropped my tank and cleaned it and installed a new fuel pump. and now my gas guage isnt working. i have the xe v6. The best way to break the lock tight on the tank bolts is with a torgue wrench. and even then its a hassle. i only get about 13 mpg. guess we just have to deal with it. Great car though. its still looks brand new. nothing is damages.

WD21 pathfinders are notorious for having bad starter relays. Cheap part, it's a little blue plug on the right side of the engine compartment. Get a nissan spec one if you can, I went through 3 generic ones before getting one from nissan and I haven't had that problem since.

Also, where did you find a 3.8 L pathfinder? All engines offered for gen 1 are variants of a 3.0

My 95 pathfinder acts like it running outof fuel going down why when its hot outside acts like your pumping the gas pedal up and down don't do it when its cool any ideals why thought maybe fuel sumo getting hot and shutting down
