People,

GTR Cam on here is having some wiring issues and is after the wiring diagram and possibly the entire Workshop manual for a R33 GTR.

Now he has the one for the R33 GTR however the wiring loom as on his car is VERY different, unsure whether this relates to it being a V-Spec, however word is that this is the reason and there is a separate manual.

Any help would be greatly appreciated as we would all like to see this car back on the road ASAP.

If you have anything that could help please email me at

Or GTR Cam

Thanks

Neill

Oh god...not more zip ties

Nah mate.....

Stock ECU uses a twin fuel pump set up, ie high & low, whereas the Motec uses low only (std setup)... This appears to be why it's missing at the top (on the street under heavy load) as a result of the car squatting, there's not enough fuel being drunk.... hehe. This would explain why the missing at the top of the rev range isn't happening on the dyno (ie it's not squatting)...

So the guys are using a connector plug to mimic the stock ECU setup so as to ensure enough fuel is delivered...

Keep ya posted!

sounds rather odd as with new wiring+relay setup, fuel pump should receive 13+ volts constantly so it'll pump as much as it can all the time (wears out the factory pump but too bad :P , upgrade to bigger one ) :confused:

Agree with the Jap man on this one...the pump operates on a continous feed basis with unused fuel returning to the tank. And the fact is your using a Malpassi to reg fuel pressure so this should not alter becuase of the ECU...

*Looks at Walbro fuel pump on net*

Seems you will have to keep me updated!!!

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
