2001 saab radomly won't start or even turn over

Asked by maverickjohnson Sep 21, 2011 at 09:35 PM about the 2001 Saab 9-3

Question type: Maintenance & Repair

My 2001 saab  won't start sometimes or even turn over. All the gauges and the radio come on but that's it and now my buttons on my key won't even work and there is a dinging sound that won't go off while the door is open and the light doesn't dim ON when you pull the key out of the ignition ( it used to do this) Any ideas of what is going on?

Hi there, Firstly, does your car start well first thing in the morning? If it does, fine. But then if it won't start for the rest of the day, say after you have done your groceries and then this issue happens...like intermittently Well, if that is the case, it could be due to your neutral safety switch being faulty.(ebay sells some used ones) I used to have this problem on my 2001 9-3 Intermittent no start problem - you turn the key to start, all of your interior/exterior lights work fine but nothing happens. 5, 10, 30 minutes pass and then it starts. The neutral safety switch sits onto the top of your transmission and lets the car know if it is in park, neutral, etc. If it doesn't think you are in either P or N, then guess what, no electricity gets to the starter. Try cycling your gear selector a bunch of times to see if you can then get it to start in either P or N. Chances are it may work some times. But it gets real frustrating, especailly when you are in a hurry. And believe me that's when it relly won't start. Another trick I learn't and with much sucess is to pour water over the neutral safety switch and then get in and start your engine, it'll surely fire. I do hope this will help you. Cheers.

Sometimes the DIC connections get corroded if not installed correctly, like mine. I'm a N00B, but if I scrape the connections it works again.

Had anyone had any problems w the gas gauge not working? I've searched for a fuse or relay online and through parts stores they can't seem to figure it out either. When the computer says refill fuel now I get topped off at 5-6 dollars every time.

I also had this problem for years -- starts fine sometimes, other times nothing in 2001 turbo convertible. Drove me crazy. I'd give it a break for 10 or so minutes, and it was good to go again (not fun if you're in a hurry) .Here's what I learned: The Saab has a really complex electrical system: when the amplifier (which is connected to the CD/radio) starts to go bad (due to age or moisture) it sucks the battery dry. The amp can be on the fritz for months or even years before it finally kicks out altogether. Here's the solution: 1. Disconnect the amplifier and get a decent stereo (or use an iPod/iPad) -- in the convertible it's in the kick panel in the passenger side; in the other models it's under the driver's side seat. 2. Get a new battery -- the one you have has likely been badly battered the bad amp. 3. Go about your merry way -- it'll start every time. How can I say this with confidence? I realized my battery was over 5 years old -- when I replaced it, the Saab started every time. Then, I blew out the 16-year-old amp during a beautiful fall day. Bought another amp on eBay and installed it. Went shopping -- car wouldn't start! Removed amp. Installed a new Kenwood radio from Best Buy with JBL speakers from Crutchfield. NO PROBLEMS EVER! This problem of not starting nearly sent my beautiful Saab to the junk yard: I'm glad I took the time to figure out how to fix it. Oh, and the new stereo --- unbelievable! If I had known that the amp was such junk I would have done this years ago.

Try replacing the direct Ignition coil cassette, if that has be replaced then it's your neutral safety switch.

I have the same problem but with a manual transmission, so presume this wouldn't be the neutral safety switch. any other options?

My 2006 Saab 9-3 Aero Wagon shares many of these symptoms and it took me a fresh battery (not it), several times getting stranded, an OBD2 scanner and some patience to figure it out. I traced my issue to a CAN bus failure that also periodically affects the instrument cluster when driving. My problem seems rooted in the wiring harness and connector that feed the antilock brake module. When I lose connection while driving, the instrument panel lights up like a Christmas tree and when it begins to respond again, I have a check engine light (CAN bus failure) and traction control failure. I suspect that the failure on the bus communicates an abnormal signal to the ECU which bricks the car via anti theft system when it occurs at startup. Same symptoms: wait for an unspecific amount of time and it starts with a diagnostic code U0212 (Lost communication with steering column module) stored on the ECU. My fuel gauge hovers around Empty which points to fuel pump shutoff by the ECU. I suspect a bad connection although I haven't ruled out electromagnetic interference or a ground issue on the bus which has a few poorly twisted pairs. Try this: turn ignition to on like you are attempting to start the vehicle. If it starts, GREAT! If it doesn't, and you note an issue with the fuel gauge, lower the driver's side window so you can hear the instrument panel chime from outside the vehicle. Pop the hood with the key still set to on and poke around the connector and wiring harness associated with the ABS module that is located between the firewall and the battery box. If you hear a chime, turn off the ignition and try to start again. The crazy thing is that I was ready to replace the column integration module based on the diagnostic code when it seems to be associated with the harness under the hood...Euro-gremlins. I'll keep gathering data and report back.

This happens to me intermittently since I bought my Saab. There is a common problem with the security settings and the battery in the security system. They get really weak really quick and if the battery is weak in the security system it puts the car in neutral safety mode hence why it won't turn over but the electric comes on. If you replace that battery you shouldn't have any problems going forward. If you're in a rush and trying to get it done quickly temporarily what I do is I flip a bunch of switches like the lights mirrors windows lock the car walk about 30 feet away unlock the car and try and turn it over. It tends to work most times I've never had it fail just sometimes takes a few tries

I was having intermittent start problems with my 2001 9-5. After being stranded one time too many I decided to troubleshoot the problem myself. Narrowed the fault to a bad NSS (Neutral safety switch) located just below the battery shelf in the engine compartment. Ordered online and replaced the part. Haven't missed a start since. From reading similar threads this seems to be the main culprit. Hope this helps

Hey Harlan. My 06 aero is having the same problem. Thinking it's the abs module itself. Any luck with yours?

Bvd1118-Seems like a wire harness wiggle test brings it back for me. I'm waiting for a harder and more permanent failure before I replace the ABS module. I haven't ruled out ground faults and loops yet but I do have an intermittent left turning signal fault that could be related to a dirty ground. I poked around a bit with a multimeter and I need to mess with the ABS module some more and clean the grounds. Right now, I can live with an intermittent issue that can be "fixed" with 30 seconds of wire wiggling.

I pulled the abs module and re soldered all the connections. It seems I had a bad connection somewhere that was causing the issue. There is a youtube video online covering this. 1000 miles later and no issues have reemerged. Beats having to buy a new abs module!

Same issues - in my case, the fix was the Crankshaft Position Sensor - a $19-$30 part - labor is around $85-$125
