Just had my fuel pump replaced, no more humming at start up.

Discussion of Infiniti's amazing (and underrated) sport-luxury crossovers, the EX35 and EX37. For 2014, the EX series will be renamed QX50, in line with Ininfiit's new naming conventions.

I go on Monday to have it replaced.

Does anyone know where it's located? And are they dropping the tanks or doing it from the top?

I really REALLY hope I do not get any annoying interior rattles when they button everything back up.

My dealer said it's UNDER the BACK seat (not the drivers seat as someone else reported) He also said to bring it in with UNDER 1/4 tank of gas if at all possible and there is typically NO fuel spillage. We followed his recommendation and our EX was odor-free, except for a little "Lysol/New Car" smell that disipated in two days. The Service Manager said that they "use a special deodorizor" to flush around the pump area, just in case a drop or two might have spilled out of the old pump upon removal.

Hope this helps the others -- 1/4 tank when you go in!

Is this issue caused by a high idle speed at startup?? I noticed that the car typically starts out around 2K rpm. When I mentioned this to the service manager at my Infiniti dealership, he stated this is normal.. I noticed even though I purchased my car in 12/08, the build date was 1/08. Does my car have this issue?? Any help or guidance on this issue is appreciated. Thanks!!

the higher RPM on start-up is normal. Especially in Winter months. It does this to get the Catalytic converters up to op. temp more quickly, thus polluting less for the overall emmissions cycle. All newer, injected cars are this way. The RPM's should drop back to "normal" within a few minutes of start up.

The fuel pump issue is a whining/whirring sound, much louder than normal -- you'll know it when you hear it.

As for your car, it probably sat on the lot (or another Dealers lot - they trade cars sometimes) for 9 or 10 months. Built in Jan. 08, probably received at the dealer in Feb. or March of 08, then you bought it in December. Yours MAY get the fuel pump noise, OR the dealer may have already fixed it per the TSB that's been out for awhile. Your service advisor can look it up to see if your car was already fixed.

Should it happen, you will know it. You have 4 years of warranty, so don't sweat it!

I had mine replaced 2 times. The first replacement was bad. When I left

the dealership I had a quarter of gas in the tank and the screen says 55

miles to go before empty. After 10 minutes, it says 0 miles before

empty

I was stuck on the interstate during rush hour traffic and was sweating like

a pig I though I would end up pushing it and everybody would

be staring at me... (I was wearing my favorite BOY GEORGE tight pants

LOL! just kidding

Thank GOD! the next exit was about 1/4 mile and the first light has a gas

station in the corner. Yeah! I went back to the dealership the next day

and they had to order another pump.

It wasn`t really bad , since I had a chance to drive a nice G35X (1st) and a

fully loaded EX35 AWD

I had mine replaced yesterday. No gas odor...and no noise on start up. It wasnt "awful" before and I honestly didnt notice it until I read about it here.

Now other then a little "Vrroomm" I hear nothing when I start the car.

Oh and JBA Infiniti in Elicott City MD has been a great dealership so far.

Can anyone provide me a copy of the ITB08-25 TSB? I can't seem to locate it through a search.
