Hi guys,

I put an 040 in the car a few months ago. Ran fresh wiring, new relay etc etc

Up until today, you could just hear it humming/sucking away. From inside the car you could just hear over the exhaust & from the outside you could barely hear the pump at all.

Today it has started whining/buzzing and it is significantly louder than normal. Should I be worried?

if it makes you feel better, my 040 makes a hell of a lot of noise, all the time. gurgles, buzzes, whining...

very noisy pump. car has always been fine though, been running it for a year or two now.

I don't have a gauge so I haven't been able to tell. Car seems to be running fine though.

Mate go get an autometer gauge that you can put in your engine bay they're like $20 and hook it up to your regulator, its such a cheap mod for important information if you're running more than base fuel pressure.

Check your tank for shit!

Pull the pump out and inspect it for black dusty crap on the bottom. If that or anything else is on the strainer of the pump you need to remove the tank and have it cleaned.

My 044 went this way too, exact same symtoms. Started also getting fluctuating pressure.

Ripped it out and went a 023, still never figured out why it died. Was a genuine 044 too, strainer was clean, good wiring etc.

There just getting so hit/miss now it's not funny.

I really don't think it's anything to worry about, my 044 has been like this for a couple of years now with no issues what-so-ever.

My guess as to WHY is that it's probably working harder to pump the thinner hotter fuel around. It's basically because there is excess fuel travelling to a hot engine bay and back. Standard, our cars run a control module that drops voltage to the fuel pump at idle, these tend to get removed when aftermarket fuel pumps go in.

Same with mine. Mine has a very loud buzz & grgule sound since day 1 of getting it installed when my stock one died. The exhaust noise covers the pump noise up inside the car, however outside its very noticeable when you are near the rear of the car.

Being fine for about close to a year now.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
