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..

I just bought a "barn find" r34 and it had the same problem - turned out to be a dud connection on the positive battery terminal. Was cranking fine with a new battery, had all the ignition lights, just not enough current for the fuel pump

Is said barn red?

Seriously though, start from one end of the system and work through. Power to ecu, power to trigger wire, power to pump relays, which should be under the parcel shelf, next to the battery IIRC, power to tank lid connection etc. (I'm pretty certain i got that order right... been fighting the flu for the past 24 hours and the brain is a bit foggy)

If all is dandy, pump itself may be rooted. Sitting in stale fuel for 3+ years will clog it up with varnish pretty fast. Did you clean the tank out or just drain it? Prick of a job to do in a 33

I thought My bosch 040 had died a while ago, and after replacing the pump, it actually turned out to be the pump trigger wire burnt out from another unrelated issue.

As per Q2 and 3, you can do both, but both won't work if there's another wiring issue, or the pumps is rooted, unless you simply hardwire from the battery to the tank lid connection.

Hope that helps you in any way.

Hi

Still have NO POWER to pump.

Checked all fuses and swapped relays.

ZILCH

Connected 12volts direct to pump and turned key YOU BEAUTY! .....................IT RUNS!

Will now trace and find the break.

If not, should I supply 12volts from battery direct to a relay AND switch it from ignition side of fuse box??

Could be a few thing but the three most obvious to me are 1) the fuel pump control module which povides the amperage to the pump which is control with the signal from the ECU, 2) the fuel pump relay on the back wall of the truck, 3) the alarm which should be spliced into the fuel control signal from the ECU to cut that signal so the pump doesn't activate

I just went through this on another car. My problem turned out to be a bad ground wire AND a faulty pump! Sometimes the ground was there, sometimes it wasn't. Sometimes the pump ran, sometimes it didn't (internal fault in pump) Check the ground wiring and bang on the fuel tank, doing so might make the pump run, which if it does you know the pump is faulty.

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
