At 36,000 miles my 2001 Olds Alero started having passlock starting problems. At first it was every other month and then after 2 years it happened with every other turn of the key. Since I am not the least bit mechanically inclined, I tried any and all procedures suggested on the internet except cutting wires, or installing a new switch. Eight months ago I decided to clean the grooves on my ignition key with a squirt of 3 in 1 oil. THE CAR STARTED RIGHT UP. I did it again for the next 3 days to gain little confidence in the procedure. THE ALERO CONTINUES TO START EVERY TIME
  
Now once a month I oil the key, push it in and out of the switch slowly a couple times. When starting the car, do not jam the key in quickly and turn. Take your time. It seems to be a very sensitive switch, and needs a little TLC to prevent dirt build up. Try it. A little 3 in 1 oil squirt might save you a $500 repair bill. I told my GM dealer mechanic about this solution. He said "Yeah, it might work"
 
Other Olds owners have tried this easy solution with favorable results. Try it and see if it works. I would appreciate hearing your results-good or bad. Don't use any special ignition key lubrication from an auto parts store. Just plain old 3 in one oil. Ja

#27 of 45 steering not locked, can't start by gary_william

I cannot turn the ignition to start the car. the steering wheel is not locked, either (it turns freely in either direction). Is this a transmission lockout module problem, an ignition module problem, or a steering lockout module problem?

Hi I have an 2003 impala, it started stalling a year back, at that point of time it used to be once in a couple of months, but of late ie, for the last 3 months, it happens weekly once....it stalls while driving and doesn't start immediately, may be after 45 minutes it would, took to the mechanic ther was no code. It would give check engine light when ever I had this problem. Finally got the transmission , powersteering fluids changed and spark plug system changed costing $800, now after changing al these and spending so much , it is again giving the same problem , yesterday didn't start from the parking lot and today stalled while driving and again didn't start from the parking lot. I f any oone can help

I had a very similar problem. but in my case, no check engine light. I researched the problem and it looked like a high probability of the problem being the crankshaft sensor. Replaced that and problem went away.

Does anyone know what emission code 420 controls, and how can it be repaired?

P0420 is Catalyst system efficiency below threshold. I assume there maybe a problem with your catalytic converter. There was a recall for converters on these cars especially from 2000-2002 you will notice a drop in power and poor fuel economy when it fails.

My 2003 Chevy Impala LS engine misfires when accelerating or in cruise with drop in RPM, flashing check engine light, and lurch. No computer readouts except misfires all cylinders. Changed coil, harness, spark plugs, alternator, and catalytic converter twice - no help. Condition is intermittent.

I was having the same intermittent trouble as you my car finally threw a code when I was a few miles from autozone, it turned out to be a crank shaft sensor was bad and the part was only $25 to replace but the labor is what cost you because it is buried behind the pulley. but since i got mine replaced i havent had any problems.

i had this problem one day while i was at work.....it turned out to be a corroded battery terminal that caused this.....we only found this out because we tried to jump it and nothing would work out for it so i went to take the battery out and the terminal ( metal disc the cables screw into) was so corroded inside they fell out.....i went and got a new battery and it worked like a charm.....my suggestion is check your terminals for your battery
