Ive got a very weird problem that started happening over a few weeks, and would only do it here and there now it does it 9 times out of 10 and its getting to be very annoying.

Basically my car wont stop running when i turn the ignition off... When i switch the key off and take it out all the dash lights go out, the clock dims, the stereo turns off etc but the motor keeps running... it acctually drops slightly in RPM but doesnt stop. A few times i have switched the key back and forward from off to on and the motor will stop.. but lately it just wont stop no matter how many times i jiggle the switch.. i basically have to put it in 5th and stall it to kill it.

Seems weird to me that the switch is powering everything off... except the motor/ecu etc.

FWIW i have done the fuel pump rewire mod running a power wire from the battery and a relay which is switchable from the existing fuel pump wiring... my turning off problem isnt related to this tho as it started doing it before i did the rewire mod. Plus ive wired it up properly on the relay :)

So yeah.. what could it be??

hey mate a similar thing happend to me when my car alarm stuffed up, it shorted out my turbo timer, so when i went to turn the car off, i couldnt becouse the turbo timer was in limbo land, sorta on like glowing but no info on the screen. so yeh fixed up the turbo timer and it was all good.

but anyway check ya turbo timer, may be the prob.

there is a small chance that there has been a turbo timer fitted at some stange, and when it has been removed there is some bare wire shorting out.

another possibility is that the turbo timer is still there and hidden up behind the dash. try letting the handbrake off next time it does it. if the car stops as soon as you do that then there is a turbo timer still fitted.

thought of all that and ive looked at the ignition wiring and none of it appears to have been spliced into at any stage, handbrake and clutch dont make it stop either so that rules that out. would the actual ignition switch cause this?

i don't think so, since the accessories are turning off.

no it can actually.

ahhem..

"would the actual ignition switch cause this?" YES IT CAN

the VL with same issue as yours, Accessories was also turning off, and a new ignition barrel fixed it. hello? go see an auto electrician, and he will tell you same thing.

cheers.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
