Car Forum / Saab Cars / August 2006Fuel cut off valve on saab 9.3s convertable
Hi all Can anyone tell me where to find the Fuel cut off valve on my 1999 SAAB 9-3s, convertable. I am told by 'someone who knows', that this has tripped and that's why it wont start. Thanks for the direction Jeffro > Hi all > Can anyone tell me where to find the Fuel cut off valve on my 1999 SAAB > 9-3s, convertable. > I am told by 'someone who knows', that this has tripped and that's why > it wont start. I don't think that's how a fuel cutoff valve works. Historically, they kick in at over-rev or over-pressure limits to protect the engine. Once the RPM drops below 6K or the pressure drops below whatever, it opens back up. Do you have a local Saab Specialist garage? >> Hi all >> Can anyone tell me where to find the Fuel cut off valve on my 1999 SAAB [quoted text clipped - 8 lines] > > Do you have a local Saab Specialist garage? If you bounce the car off a kerb it's possible you can trigger the fuel shut off..?  SignatureThe DervMan www.dervman.com Thanks for the info Dervman I think its probably the fuel shut off I mean, it did indeed clip a kerb..now it wont start, where will I find this ?

I can't see it detailed in my 2000 9-3 manual. There's usually a switch somewhere. And Google has turned up empty handed... :-( SignatureThe DervMan www.dervman.com >>> >> Hi all >>> >> Can anyone tell me where to find the Fuel cut off valve on my 1999 [quoted text clipped - 25 lines] > >And Google has turned up empty handed... :-( WIS seems to say nothing about it as well. Plenty of mention of fuel cuts for over-revving, zero throttle, sensor failures etc. but nothing about an impact sensor. Cheers, Colin. >>>> >> Hi all >>>> >> Can anyone tell me where to find the Fuel cut off valve on my 1999 [quoted text clipped - 31 lines] > cuts for over-revving, zero throttle, sensor failures etc. but nothing > about an impact sensor. It's possible it doesn't have one... which is unheard of. Fuel cut offs are designed to, well, heh, stop fuel squirting all over nice how wreckage in the event of an accident...

I guess they must be relying on the ECU shutting down the pump when the engine stops and maybe when an airbag is deployed (no mention of that on WIS though). Now I come to think about it, I don't suppose a dedicated impact switch would be much better than that anyway. Cheers, Colin. Well thanks for the suggestions guys.. I will be checking some more tommorow..but I dont think I heard any whirring !! I will get someone to sit in the boot and listen (Is that where the fuel pump is ??) If no wirring...new fuel pump required right ? Regards Jeffro > >It's possible it doesn't have one... which is unheard of.

You might hear it better from outside the car. Make sure the stereo is off so you don't confuse it with the aerial. If it's not running, then there's a few things it could be besides the wiring and the pump. Check Fuse 2 and fuse 32 on the main fuse board inside the driver's door. Also, it could be the fuel pump relay or the main engine management relay. They're both on the relay board under the dash - the bottom right one, and the next one up. After that, you're into probing for voltage along the circuit. Cheers, Colin. |
