Simon-S14 Posted December 26, 2006 Share Posted December 26, 2006 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??

Guest rwkw Posted December 26, 2006 Share Posted December 26, 2006 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.

Simon-S14 Posted December 26, 2006 Author Share Posted December 26, 2006 i should make it clear that there is no turbo timer in the car at all.. which makes it all that weirder...

mad082 Posted December 26, 2006 Share Posted December 26, 2006 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.

Simon-S14 Posted December 26, 2006 Author Share Posted December 26, 2006 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?

mad082 Posted December 27, 2006 Share Posted December 27, 2006 i don't think so, since the accessories are turning off. Link to comment https://www.sau.com.au/forums/topic/148735-very-weird-problem-car-wont-turn-off/#findComment-2775597 Share on other sites More sharing options...
GTR32GUS Posted December 27, 2006 Share Posted December 27, 2006 i use to have a car which would not turn off it was because the timing was so far out and carbon build up (that what i was told) Link to comment https://www.sau.com.au/forums/topic/148735-very-weird-problem-car-wont-turn-off/#findComment-2775630 Share on other sites More sharing options...
SilverECR33 Posted December 27, 2006 Share Posted December 27, 2006 (edited) 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.

N I B Posted December 27, 2006 Share Posted December 27, 2006 Theres a relay control unit (ECC) in the ECU that can fail.See if you can grab a loaner ECU and try again.
