Question about 1999 Oldsmobile Alero

1 Answer

2001 olds alero is tempermental

Our alero has been having "issues" for 3 years leaving us stranded on several occassions. It drives just fine then all of a sudden it won't start even though it turns over fine. We have it towed (not cheap) to a garage. As soon as a mechanic tries to asses the problem it starts fine. The mechanics say they can't fix what isn't broken and suggest that we drive it until it won't work and bring it back. ARRRGH!!!!! My car is playing tricks on me and laughing all the way to the shop. Side notes: The car does crank over fine, just won't fire. We just noticed that the security light is flashing when it won't start. There is also some possible related computer problem in that the car won't run quite right (sluggish ect.) until three warning light come on; service engine, abs barkes, and trac off. Then it's fine.

    I've been reading quite a few posts on these two problems today. Can't decided whether i think they are related. I have found a quick fix (with 2 downsides) that worked to start the car. turn ignition to on - wait 10 mins. turn to off - wait 10 seconds, then fire. Worked like a charm. Downside 1 - having to leave an extra 10 minutes in your schedule just in case. Downside 2- I did read a post that said this would work temporarily and then quit working over time. The Security system seems to be the link with several of these posts. I did find a procedure for overriding the PAS security system that worked for someone else. The other warning light issues(ABS, TRAC OFF, SERVICE ENGINE) seem to have some link to the wheel bearing or hub. I did read where someone said that the dealer will want to replace the wheel-bearing, when really the connectors just need to be cleaned with a high pressure air hose. Let me just say, I LOVE the internet. My dad a former mechanic of 50 years has been searching with me and he is tickled with all of the info and communication available. I think i just found a new pass time for his retirement hours, my mom will be grateful too ;)

I had the exact same problem last year with my 2001 Alero 3.4L V6. It turned out to be that most of the copper strands in the multi-strand ground wire were broken, in the wiring harness passing over the transmission on the way to the fuel pump behind the fuel tank. The same ground wire is shared with several of the warning gages on the dash, causing several to remain lighted all the time. Both of the check engine lights, the brake light, the low oil light, and ABS light would all remain on all the time. Once the frayed portion of the ground wire above the transmission was repaired, the lights stayed out and the car started running normal, with the fuel now actually pumping gas under continuous high pressure to the engine.

I have a 2000 alero gl .i drive down the road and it dies out what 10 to 20 minute it start up .drive so far it dies again .turn key on hear the pump. i dont know what is wrong.

Can you troubleshoot? Take tools with you. When it stops, open hood, check for fuel, check for sparks. Narrow it down and maybe have a chance of figuring it out. These kinds of problems are tough to figure out when mechanic walks up a car starts for him. You're left holing the bag when it leaves you stranded.

Please see my tip at . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Roaring noise in front of 2003 olds alero gets louder as I accelerate, sounds like manual transmission needing to be shifted to next gear(this isn't a manual transmission

Have a shop look at it. It may just be a failed wheel bearing. The bearing will leave you stranded if it gets bad enough and cause more damage.

2001 Olds Alero will act **** when switching gears

My car does the same thing. I wondered that myself, I don't think that's what it is though, I don't think you have an issue with the transmission. Your car has TWO check engine lights, and with the Alero--if there is an issue with the transmission one of the lights will come on. I am not 100% positive of this, but I had a 1999 Bravada (Olds) and it did do that when I had a tranny issue.

I notice when I drive my 2001 Alero my right leg gets SORE from pushing the pedal so hard. I think it is age, not the transmission.

READ YOUR SERVICE MANUALS. I don't get why people ignore them, honestly they have a wealth of information in them...could have saved a lot of people lots of money when people started claiming their car wouldn't start when it was a security feature that is listed in the manual that came with the book.
