2006 Nissan Altima: fuel pump failure

Filed Oct 9, 2025 · Electrical, Engine · LA

I have replaced the water pump, the belt, the thermostats, the rotors, the brakes, the fuel pump, the evap vent valve solenoid, the spark plugs, and fuel injectors and my car is STILL throwing the codes P-0462 and P-447. I've checked the wires and they are good. My car keeps misfiring and stalling now and my fuel pump doesn't have a fuel level sensor. The float bar is brand new as well as the fuel pump. And my dashboard speedometer is 10 miles off. I've tried everything and it's still throwing the same codes.

On 5/23/19 my son was driving this car on the interstate when the car began to decelerate and completely stopped/shutdown on the highway. It's a blessing he was not injured/killed when this happened. The diagnostic check revealed a sensor that the fuel pump needed to be replaced, so after an expensive repair on 5/24/19.then on 5/25/19 while driving to work, the car began to do the exact same thing again and stopped on the highway. Nissan needs to address the issue with this car asap before someone gets seriously injured or killed!!!

Car will slow crank randomly, it does it completely intermittent, even when its cold or hot, the fuel pump works perfectly, the starter is new, it has new crank and cam sensors, the battery and alternator are in working fine, the spark plugs and ignition coils are brand new, it has been doing this since I first bought it, it had 148,000 miles, sometimes I had to push the key twice or more, the engine will crank with the starter but will simply not turn on, after I do it twice or more then it starts, I have tried every trick in the book to see if it stops happening randomly, I just want this car to work fine or just not work at all, I dont like this game. I have had over three professional mechanics take a look at it and nobody knows what it is, it just does it whenever it wants. No matter the weather or engine temperature or voltage or fuel pressure,

While driving on the i95 the car shut off and would not restart at 55mph. Thank god, I did not get into an accident and was able to coast over to the guardrail. I had to have my car towed to my mechanic that informed me it appeared to be the crankshaft sensor and said since it was a recall item I should have it brought to my local nissan dealer. I had the car towed to miller nissan in fairfield ct and informed them of my mechanics findings. They checked the car and told me it was the fuel pump and replaced it even with me expressing that my current mechanic already checked that. After replacing the fuel pump they called me back and said it still wasn't working. It ended up being the ECM along with another sensor!! I expressed how upset I was that this sensor failed why I was driving at a high speed on the highway! I am currently working with nissan corporate recall department because everything I'm reading is still indicating that the crankshaft sensor could cause malfunctions in other sensors in the car!! I'm not happy that nissan is charging me for the new fuel pump they installed along with the sensors totaling $1,943,00!!

Car shakes when idles as if it will turn off, but only sporadically. This started at 24,000 miles. Check engine light comes on throwing various codes. Dealer has put on new gas cap, gas seal, fuel pump, fuel canister and air flow regulator. Car still shaking, check engine light on again and after 11 times in the shop...here we go again to the shop so they can check the code, put in on vacuum, drive it around and then tell me again it's all fixed. I am in a never ending loop of being inconvenienced with an unreliable brand new car. Dealer won't buy car back...trade...or guarantee a fix. I just pray after my warranty is over, I can still get it fixed.

Brand new 2006 altima 2.5s devlivered to me with a bad fuel pump. Service engine light was on. But went off after I fill up. Then came back on with the fuel light showing. Had to take it back with just 85 miles on it. Had to go back down to dealer. Service tech said I couldnt get a loaner car it wasnt covered under the warrenty. I lived 45 miles away, they wouldnt take me home. Finally went to the salesman and he gladly gave me another car to drive until it was fixed 3 days later.
