#24 of 49 slow drain maybe
Sep 12, 2009 (7:32 pm)
I have been experincing a problem with my impala not starting about once a week. everything seems fine but go to turn it over and nothing. have to jump to start it. took it in the mechanic said every thing checked out from the new battery to starter and alt. drains were all in acceptable range even after the 20 min. sleep mode. keyless entry dosnt work and havent been playing the radio out of fear that might cause it.

Hi,I bought a 2005 impala,3.4, a few months ago and I am sorry I did.I had the intermediate shaft replaced(common problem)felt like the steering wheel was coming apart at times.Then the service engine light came on..took it back to dealer and they couldnt find the problem.Had fuel injection cleaned.Then security alert came on message centre at times,while driving.Then my car just wouldnt start at times.Maybe a few hours later it would start..maybe not.Took it back to the dealer and they couldnt find a problem.see,the car would start there.no messages either.
I paid for a scan that turned up nothing.Someone suggested i remove the car starter.that was in it when i bought the car,(not factory).I had the dealer remove it.
2 weeks later..all fine...THEN,..security light came back on,service engine light,and
as i was in a parking lot waiting for it to decide to start ,someone suggested that i turn the key to acc and leave it on for 10 mins ,then start the car.IT WORKED.
The next day I took it to the dealer ,put it on scan,they said wires in bcm came up.
I am also having ignition switch replaced.Sure am seeing alot of this problem.Should be a recall for sure.Will update if it works..or not.
#26 of 49 Olds, Pontiac, Chevy passlok starting problem
Oct 13, 2009 (3:56 pm)
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 49 steering not locked, can't start
Oct 16, 2009 (9:15 am)
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?
#28 of 49 stalling isssue with 2003 impala
Nov 21, 2009 (12:14 pm)
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.

#31 of 49 emission code 420

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.
#33 of 49 Engine misfires - 2003 Impala
Mar 29, 2011 (7:55 am)
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.
