now i understand that my car may be different from yours (S1 as opposed to S2)

but in the boot near the fuses in there, there was 1 relay, which i assumed to be the one for the fuel pump (why run wires all the way to the front and back again when they can just put the relay back there).

may haps just double check behind the lining in the boot for that relay? it was a blue one from memory and yeah, mounted right next to the fuses.

i'll have another look at my car tonight if nobody else can help you find it.

+1 You can test the relay by letting the pump prime (from off to on) then start the car and it should stay on. But teh relay mounted on the fuse box next to the battery IS the fuel pump one.

i don't mean to be rude, but you must be blind or something (something being someone has done some weird wiring in your car)

there is only 1 blue relay in the boot next to the fuses, as shown in this handy pic below:

i just took this photo like 5 mins ago, and verified by unplugging it that i didn't hear my fuel pump.

if you don't have this relay, i would say someone has done some weird stuff to your wiring and these forums can't help you that much.

im defanitly not blind mate. all the wiring looks untampered with and standered its just that my car is differant to coupes and s1's.the car did its no fuel thing again today wen i went to test starter after doing the clutch so i swoped out the relays in the box in the engine bay and still nothing then 5 mins later she starts up :Dpost-a313579-P1010386.JPG

well i'll be... a 33 with the battery in the front...

seems odd that they would change it from the S1 sedan but weirder things have happened and speculating doesn't help you now.

that doesn't look like many relays so i imagine that there must be another set somewhere unless again, they did something weird in the S2 and reduced the amount of relays needed.

sorry, but i'm a bit out of ideas without poking around the car myself. hopefully someone with a S2 Sedan can help you more.

ok so i think ive found the fuel pump relay thort there were 2 ? so if you un plug the blue one the pump doesn't prime plug it in and she primes up. so i swopped out the relay with a good one and it still does its random no fuel thing still, today the pump has just stopped all together o and its a new 040 by the way. i think it may be time to run a new wire straight from the battery, i have no idea about wiring relays though and were to get the trigger from im shore theres something on the forum?post-a313800-P1010387.JPG

a little more info on this wierd situation just remembered woops when the car was taken off the rd a year ago on its last drive to work before i had to get it towed the head lights dimmed and it was running a little off, felt like it was of tune almost i just ussumed it was my coilpacks on there way out and today wen it was running then conked out the dash lights stayed on for about 5 10 seconds after i turned the key to off :)

little on the car its fairly stock cat back, gutted cat, pot filter and the stock comp but it has an impule badge on it i think my car is one of those impule skylines with half the shit missing probably pilfered by the import yard its still got the dash and bumper

things ive replaced coil packs 040 pump with stock wiring couple other things to but shouldnt affect the way it runs clutch and radiator

ok so if you hold the raley in your hand and crank the car a few times the relay is triggering fine but still no prime sometimes it will prime for a couple seconds but thats it enough for the engine to fire about twice

I don't reckon the relay is your issue at all.

How confident are you with the 040 installation? Have you checked to see how much voltage the pump is receiving?

just checked then and theres nothing at all coming through to the brown plug with the 2 fat wires and i pulled 11.7 of 2 of the skinny wires 3 wire plug

the plug with the two fatter wires is definitely the pump power connection.

when you tested it for voltage the ignition is switched to ON yeah?

you checked the fuse?

yep had the little sis turning the ign for me and the fuse is fine theres only one fuse ye the one in the ingine bay fuse box

yep only one fuse mate - i know the coupes have this particular fuse in the boot (as i used to own one). I'd check my sedan for you right now to see which fuse, but i broke my foot last weekend/am on crutches :P so I cant move a lot atm.

Other than pulling out the relays for testing and installing the 040, have you modified any other wiring / electrics since the car was last running fine?

cheers, it does suck - not being able to drive especially - left foot injured, no way i can kick the clutch pedal! lol

anyhow - maybe try testing that there is power at the fp fuse with the ignition at the on position. Cancel everything out one at a time. Somethings definitely stopping power to the pump

yes mate and ive just figered it out and went on my first drive in a year yai. all along i was thinking i had bad connections in my mind. went outside and she fired up so i left it running cos i wonted to prime the cooling system whilst i was standing in front of the car i noticed a electrical type spark reflecting of the cooler pipe it was the red thing for the positive that holds all your positive wiring and the plugs were all corroded and falling apart from the top you would have never niticed because of the pretty red cover i feel like a dosh bag now huhu. so i think ill head down to the auto store tomorow get all the stuff to make up new main wires off the batt just to be shore

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
