Hi there, This maybe my first post, so please help me out here. I recently acquired a 1996 Nissan Skyline R33 GTS 4 door that HAS NOT run for 3 1/2 years. I have drained the fuel tank, changed the fuel and air cleaner elements. A new battery has also been installed. It cranked up and fired into life after a little coaxing. It ran for a few minutes and then I switched it off and changed the oil and oil filter. Now the engine will not fire up again. Since changing the fuel filter and air filter, the fuel no longer flows! There is NO clicking of any relays and NO noise from the pump. I have checked under the bonnet fuse box and FUEL PUMP fuse is serviceable. The fuse box under the dash has ALL serviceable fuses. Problem is, it is all in JAPANESE! The Google search did not help for the translation as the detailed page dose not match up with the Amp rating or layout of IGN, ACC or BATT. My main questions are: 1/. The relays are quoted to be inside the boot between the tail lamps under the boot catch assy They are not there! Where would they be? 2/. Is there any wiring mods that I can do simply that will get the pump running? 3/. As per Q2, can I put in a HOT wire and run the pump via a relay I supply and trigger it from existing switching wire> I would like to see this car up and running tomorrow if I can find some quick and easy to do solutions. Many thanks in advance..

DR30 wiring diagram or factory manual Hi there, trying to chase down a wiring diagram or a factory manual for a DR30. engine turns but won't start. Looks like no voltage to fuel pump. has aftermarket computer running extra fuel pump relay. need to find the missing voltage on the input to the extra fuel pump relay. a wiring diagram would be great so I can see how the original fuel pump works and where this 12 volt comes from. Should run through ignition via fuse somewhere but I can't seem to locate it. any help appreciated.

The market is saturated with fakes at the moment.... Here's a heads up https://www.facebook.com/media/set/?set=a.614011205349032.1073741828.142150452535112&type=1

Hi all, I have an auto r34 GTT running on 98 and am thinking about getting my turbo highflowed by hypergear. Just wondering what injectors would suit this application without being overkill and what fuel pump as well. Also here's a list of the current mods, anything that should be changed/added ? Blitz return flow fmic 3" turbo back exhaust with de cat Trans cooler Split fire coil pack Ngk irridium plugs gapped at 1.1 (think I need to decrease the gap, yeah?) Greddy B spec II ebs Z32 afm Apexi pod Nistune Will also be getting a metal induction pipe Any help would be greatly appreciated

Can't seem to find a decent write up on how to re wire my fuel pump. My old plug melted. Any help would be appreciated, I'm more of a picture person lol . Thank you

R33 Gtr not getting fuel Hi guys, i ama new gtr owner. Imported the car frm japan about 2 yrs ago and and the car in the garage. I am finally getting it ready to get a compliance and i ran into a problem. Up untilnow the car had been starting up fine and its safe to say that the car has only been driven about 1km in these two years but i used to regularly start it up. Yesterday i went to start up the car, at first it turned on for about 4 seconds and then turned off. The car is turning over and getting a proper self but is not starting. So i checked the spark plugs and they are fine, next i checked the fuel filter and that fine too. Ihave also checked all the fuses and they are fine. Took the filter off to see if fuel was flowing when i turn the key and there was the problem. There is no fuel coming through. Then i took out the fuel pump, checked it with a car battery and it works fine. But when i put the key in i cant hear the pump prime. I think i have checked the correct relay with a multimeter and that is working aswell. It was next to the battery, have added the photo of the relay. Can you guys tell me what could it be? Any help is appereciated guys.

R33 loss of power (fuel pump) Hi guys, having problems with my r33, fueling issue I believe. I've had a walbro 255 fuel pump installed for over 1000kms and haven't had problems besides it taking a bit of throttle and a few extra turns of starter motor to start. But that's ok. The problem im facing now is loss of power with the foot down. No loss in boost still running 10psi fine. Also a very loud noise when it primes at key turn, not a squeal sound quite like a quiet boat horn. I've tried having a full tank but still doing it. I'm wondering if fuel pump came off the rail? I did have a flat battery today, but I've driven it for over an hour and still doing it. The loud prime and loss of power wasn't there before I had a flat battery. I also caused a little spark near horn when installed new horn. But I doubt that could of caused anything but thought I'd throw it in thanks in advance mitch

Hi guys, I've been trying to figure out what's happening with my 2002 250GT and so far this is what I've been able to find using the NDS2 software. Fuel pressure reads about 6.8 - 7.0 at idle to 10.3 at WOT. When I disable the fuel pump, let the pressure drop then enable it again, there's a whirring noise like a stuck bearing as the pressure builds up. I'm assuming this is the high pressure fuel pump, although it isn't really specified (there's only 1 'Fuel Pump'). Has anyone else experienced this before? And if it is my high pressure pump, any idea what the issue may be? Cheers

Hi guys building a track car atm. Its a 32 with RB20det. I have no rear wiring harnes as to save money and time i have wired all the lights in myself. Now the drama i have is that ive wired the fuel pump through an iso switch and a rocket switch on the custom center switch panel i have, which in turn switches a relay in the boot to start pump. But it runs the pump as soon as the rocket switch is turned on and continues to run even with car not running. To stop pump i just have to close the rocket switch. I require someone to let me know which ecu feeed can i use to switch the relay on in the boot to then run the fuel pump only when the engine is running. I have an ecu pin out list and have tried the original Fuel pump relay wire (no volts at all) and thats it. The rest of the car has standard 32 gtst wiring looms its only the rear half thats different. And standard ECU.

could someone in geek speak, more or less explain to me how the fuel pump circuit works ? Is the relay meant to energize when the ignition is ON? see diag. Im chasing a no start, no prime with a voltage seen on the relay. Relay is good, clicks when pulled to ground. Shorting pins 3 and 5 on the relay does nothing.

i have an 88’ r31 thats on duel fuel and recently when i change over to petrol the car wont get out of first gear and limits at 2000rpm on gas the car runs like a dream. i don’t think its an injector coz’ its not missing maybe it’s fuel starvation? fuel pump is kinda loud and changed the fuel filter not long ago its got me really stumped.

hey folks. Can someone tell me please where i can locate the fuel pump relay on my 1998 r34 gtt skyline. My cars up for sale, i've been away working for 4 weeks, came home to get the car runnning and sell it and the battery's ran completely flat and wouldnt take a jump start or any charge when hooked up to a car. I replaced teh battery, but the car woulndt event start or ignition turn on. i figured i'd blown a fuse?? I checked teh fuse box under teh bonnet and yes i 'd blown the 80AMP Altenator Fuse. So off to shops i went and bought one. I fited it with battery disconnected, hooked the battery up again, tried starting it but the engine wont fire up. Plenty of ooomfff in teh starter and battery but it s like its not getting fuel. I cant hear teh fuel pump in teh boot wizz up when i turn the ignition on, i checked the fuses in the drivers foot well, they all looked ok, including the 15amp fuel pump fuse, i checked it has 12v either side also. I removed the fuel hose after the filter in teh engine bay and turned teh engine over, alas, no fuel coming through. now i know its a fuel problem. Now i'm trying to find where to locate the standard fuel pump relay to see if it's that. Can anyone tell me where i can find it and also if anyone has any other ideas on how to get her started id be very gratefull as i have 3 guys coming tonight to look at the car and it not being able to start is guna kill me. also, should i be removing teh back seats and that little pannel which gives you access ontop of teh fuel tank to check for anything?? Getting in from teh boot is impossible as i have a custom $8k sound system installed lol, cheers Gav greatly appreciate a text with advice 0422817158

Hi guys, im looking at upgrading my fuel pump but im not sure which one to choose..been informed that a bosch 040 or a walbro 255lph is the way to go just thought id see what everyone else thinks. heard people are selling the ones mentioned above for 044 and stuff. if anyone could point me in the right direction would be much appreciated. Also what injectors i should get. thanks

Does anyone know of a fuel pump that I can "directly" replace the factory one with for my N/A r33 GTS. Yes I know there's upgrade kits for more pressure etc, I'm not looking to make power I just want to replace the old pump without messing around with wiring etc, just want to direct swap it for a new one whether it be oem or aftermarket that direct fits to original bracket/wires. Cheers

Ok, so, I've been having problems with starting my 98 R33 Gts-t recently. It can vary from turning over and never firing to starting but running very poorly and stalling to working fine seemingly at random. On more than one occasion, by playing with the fuel pump wiring, fuse or plug the car will start and run perfectly, i do not know if this is the actual problem because it seems so intermittent however, i do know that the car will run roughly/stall without the fuel pump plugged in (I swear I didn't forget to connect it, i was "testing"). If anyone has had a problem similar to this and fixed it that would be great to hear but being vague and intermittent I don't hold much hope. The real meat of this post is, if i were to replace the pump is there a nice drop in replacement that doesn't cost and arm and a leg while not being from the Chinese lucky dip bag on ebay? my other thought was to upgrade to a Walbro 255 (GSS340) or a Bosch 040 because eventually my plan is to buy something reliable and diesel (and high off the ground so ramps aren't necessary for everything ) and throw some money into this car so i figured i may as well plan for power as i'm most likely to get a new car within a year. But i have read mixed things about both the bosch and walbro from a general trawl through the forums, is there a clear winner? Also if i do end up going this option, do I have to upgrade the wiring to the pump and what is the best way to go about this, my thoughts are to use the current power wires to trigger a separate fused relay. Anyway, thanks in advanced for any help Joe

Hi, My stock fuel pump was making a hell of a noise so I got a Walbro GCA3386-2 (255LPH) The mounting is different from stock. With this the strainer attaches directly to the pump while the stock pump sits about half way down the mounting bracket with a pipe to the strainer at the bottom. So with this the pump has to be mounted at the bottom of the bracket. Not sure what is the cause but on boost the car is running very lean. AFR is showing 18:1 On normal driving its fine. The car has a Haltech fitted. Am I supposed to get it remapped after fitting the pump? Do i need to change the FPR from the stock one?

Hey, Just wondering how far a standard r33 rb25 (ser2) fuel pump will go? Currently running the following setup: 3" exhaust, FMIC, std turbo, std injectors, remapped ecu and 12 psi. Will it handle this ok? cheers matty

Skyline Fuel Pump Hi Guys, I have been spending sometime looking at the fuel pump and options available for my r34 gtt. It seems that walbro 250Lph is the best choice as it is a straight swap but only good for 500 bhp. I can only imagine that is 500 Bhp at flywheel. I am looking to get 500+ hp on flywheel so that is too close to its maximum. Next level up is 450 litter however confused on what re wiring is needed . Can anyone briefly explain what is needed to install it ? I have also seen people having issues as soon as they have 3/4 of their tank empty because the fuel pump is not fully submerged. Does this impact r34 gtt? thanks

R32 Gtr fuel pump wiring Hey there, I have a r32 Gtr which is running a nismo lift pump to 2 Bosch 044s and a surge tank. I've wired all three pumps up to new relays all getting power source from the battery in the boot. Each pump has their own earth which are solid, sort and to bare metal. During my wiring of the pumps I removed the factory pump relay. I just need a hand getting the right switch feed for my relays. I'm currently using a 12v accessories wire in the boot as the switch wire for the relays so the pumps receive 12v as soon as the keys are on accessories. What I'd like to know is which wire should I use for the switch of the relays ( I thought it was pin18 black and pink) out of the ecu but that wire has no power from it. Any assistance would be great for what wire people use from the ecu. Cheers

Hi I need your help. I just changed the fuel pump in my R32 rb20det, and took it for a drive. It was responding very well and then all of a sudden a few minutes into the drive it started to rumble. It pretty much sounds like a boxer engine now and the car shakes slightly. I need some ideas or areas of focus because I'm currently freaking out
