G'day folks, Recently I've had the engine run on when turned off. It has happened 3 times this year so far this year and had my local dealership take a look under warranty. It is a known issue it seems with quite a few people reporting it. I was shown the notices faxed to the dealerships regarding this issue and to date they do not have a fix it seems as it is only an intermittent problem and is not easy to track down the cause. Obvious point of interest would be the solenoid valve. Not an easy thing to check for consistency. Has anyone else came across this problem? If so did you have a fix?The truck is a 12/03 model and 50,000kms on the clock and has been bulletproof so far.

cheers

I was recently at a site and given the same GU ute and it had this problem whenever the A/C was on when shut down. I just had to stall it when it did it.
The problem was quite bad and it did it nearly every second time the engine was shut down. But it never did it if I shut down the a/c first.

Probably coz the a/c steps up the idling speed a bit, so when shutting down, the throttle is held open a bit more than normal idle.

Have you checked any of the sensors (ie) crank, heat, timing, fuel, water and so.

Pre igniting is normally a timing or lean fuel problem from memory.

Thats another option I questioned ie: injector pump timing, lean mix etc. Once it's out of warranty turbo mods are on the cards so will be interesting to see if the problem persists. I dont use the aircon often ( i'm a fresh air man) but I haven't taken any notice to check if it does it in that scenario. We are at Talbotville on cup weekend and I will spend the time trying a few different things to find any consistencies.

Thanks for the reply

Cheers

this is a known problem

tell the dealer to contact " fix " ( they will know who you mean )

fix will then send the dealer a modified wireing harnes for the pump

Ta I'll drop in this arvo and suggest it. Chances are they did not even look at it but you have to give them the benefit of the doubt! At least it is now reported as a problem and after warranty expires it should still be covered if a fix is found. (hopefully)

Mine's done it since new, but is not a serious run-on, just occasionally it runs on with a shudder for several seconds before finally coming to a halt, then I put my fillings back in.
I put it down to the shut-off solenoid not shutting off properly. Had nissan look at it under warranty, but nothing really solved, but then, what else would you expect?
I just put up with it now.

It's not really an issue as such more so it shouldn't happen.

Apart from that the vehicle is great!

Mine has done it a few times recently too. I have the AC on nearly all the time at the moment, fresh air or not it's just hot up here in the Hill and even hotter at Innamincka. I don't know if that is an influencing factor.

I wonder if it is to do with fuel quality and the solenoid not closing properly. Once that solenoid is shut there should be no fuel and the engine should stop. It could be the piston in the solenoid sticking as a result of poor quality fuel. That should not be hard for a dealer to check. Just pull it out and have a look at it any dirt should be visible. The other cause could be dirt getting caught under the seal stopping it from shutting down properly. I guess an electrical fault that resulted in the solenoid only partially closing could also be the problem.

The site car I drive did it again this arvo.
I just floored the accel. and seen how long it rolled and rooled for before it stopped.
The volvo has been nothing but problems since they got it and we just want to get rid of it. We call it the volvo cause everyone hates the bloody thing around here and there can be full on barneys over who has to drive it.
Yet the Datsun dealer keeps telling us it's in perfect running order.
