Hi All,

Im having some isues with my car currently and i was after some advice. The problems i am having are as follows:

1. Fuel Pump is making an audible whirring noise and has done for some time

2. Car is guzzling fuel even on the highway (best i got was about 12L/100km over a 1000km stint and it was reasonably hot day at about 35 deg)

3. The exhaust note of the car has changed significantly recently and it now burbles alot like a WRX does.

Car type: R32 gts-t

Current mods include: pod filter, BOV, hybrid intercooler. Still running standard turbo/boost.

I have a sneaking suspision that my fuel pump is somewhat shagged but i was hoping that someone out there might have experienced something similiar and can lead me to the exact problem.

Cheers

Laine

yeah i was gonna say sounds like shes running on 5 cyl... check coil packs (could b a loose plug as this happened to me once)

Thanks guys.

Checking them now but im not sure how to check the pack itself? Any ideas as to the best way to see if they are working? I have checked connections and they all seem ok

Cheers

My money is on a dead coil pack. Simply remove the valley cover and disconnect the coils one at a time while the car is idling till you don't hear a note change in your exhaust. This will atleast find the troubled cylinder. After finding this change the coil from a known working cylinder and see if the cylinder you swapped the coil from now has the problem. If so you have a coil pack that needs replacing. If this doesn't fix the problem remove the spark plugs from the troubled cylinder and check it. It that's fine then it's either your ignitor box or a blocked/troubled injectors.

Yeh i tried changing them over and the bugger started working again. It appears to work when it wants too so i think i will get it replaced anyway. Anyone got one handy they want to sell?

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
