Car Sounds Like A Wrx, Guzzles Fuel!

[nissan_gtr35]

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

12l/100 kms could be great depending on what type of car you have...

my GTR gets around 20l/100 kms.

what car are you talking about mate?

[lordsnipe]

I have a 33 gtst.

i get 12L/100kms for highway, 15-16L/100kms for city driving, thats a r33 gts25t, worked engine high boost, but babying it around most of the time, most import thing to note is 550cc injectors and nismo fuel pump

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

i'd say its o2 sensor.. is it gurgly at take off? but on full boot not too bad?

[nissan_gtr35]

Well ive checked all the ignition coils and it appears that the second one from the front is shagged.

Thanks for your help guys much appreciated.

is there just a crack in the side of the casing? if so, get some electrical tape. seems to fix the problem

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?
