Hi guys, just wondering if anyone else has experienced this problem before. Hopefully it's something simple.

I'm in the final stages of my build which includes changing from a power fc to a haltech platinum pro.

When I switch the car to reds, the air con fan turns on. When I turn the car off and take the key out, the fan stays on as well as the reds. The fuel pump does switch off as well.

The turbo timer is connected but it's not switched on.

Anyone seen this before? Thanks in advanced.

Something is being powered when it shouldnt be, and this is backfeeding the ECU causing it to stay on. Is there any wiring in your engine harness or near the ECU connector that isnt standard?

Ive seen on some Stageas the A/C relay was fed with constant 12v from the battery, causing the ECU to remain on. Try removing the A/C relay in your engine bay, and see if the problem goes away.

I'll have a look when I get back to his place tonight.

We are going to plug the power fc back in and see if the problem continues

is this a R34 OR R33?

I know for a fact R33 GTS-t front fan isn't triggered by the A/C trigger but is triggered by the thermoswitch located on the bottom driver's side of the radiator.. however on the GT-R PIN6 triggers the fan.

It's an R34. I'll check this out as well.

Got a feeling it's something to do with the wiring. We put the power fc back in and the problem was still there

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      By Hendasto · Posted

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!

      Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.

      https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
