Got in the car one day turned the key and got nothing. It was almost like the battery was dead but I had full power to all my lights and radio. I got out of the car really pissed off and was pacing back and forth trying to figure out what it could be. I left the car where it was and came back a day later. I figured what the heck and put the key in the ignition and low and behold it started.

So I got on my tablet and Googled 2000 Chevy Impala not starting. It came back with a ignition switch failure. That made sense so I ordered one and took the whole dashboard apart to put the damn thing in (It really wasn't that hard, just a pain in the ass). I started the car several times to see if everything worked. It seemed fine so I drove home.

The following day I went to the store. Came out and turned the key to guess what? NOTHING!!!! I sat in the parking lot and cried. I called my brother and told him the car wasn't fixed. He happened to mention it to a friend of his that used to have a 2001 Impala. He said that it was the Multi-Function switch. I didn't believe him but I ordered one anyway. Turns out he was right.

So if your Impala has any of the following issues it's more than likely the Multi-Function switch which I found on Amazon for $37.50 plus 7.99 expedited shipping. (if you can wait shipping is free). Intermittent problems: headlights go out, turn signals don't work, fuel gauge bounces everywhere and car doesn't start. The longer you wait to replace it the more frequently it won't start.

This car has been nothing but problems. Multiple times where the car would stall or not start. I started with changing the mass airflow sensor and cured the problem. Then two months later same thing happened so I changed the coolant temperature sensor and wires which then again cured the problem and the car was wonderful. Now its back at it. It starts up sometimes but idles at 1200 rpm. Not even a rough idle but a smooth clean idle. But slowly lowers rpm and once it hits 900 it jumps and shuts down. So I changed the idle air cleaned the egr valve and changed the crankshaft position sensor but still hasn't solved the problem. The fuel pump is brand new and sometimes it clicks when I turn the key and sometimes don't...idk what the hell is going on. There are no codes and after three mechanics I cannot find out the problem...I'm a college student that has enough trouble paying school loans. I baby this car and keep it clean and up to date but I need a specialist that knows 3800 series 2 motor like the back of their hand. Please any help I need my car.

Well..... I thought I would join the crowd of people that have the same problem as I! My scenario was... one morning it was cold and I went to start my car to warm it up. Later I started loading my car with things I needed for the day and later as I went to my car to head out and it stalled! (owned car for 12yrs. never has happened) tried to start and nothing. At first I thought because of the cold weather maybe I possibly may have gotten some water in gas....walked up town and got a couple bottles of dry gas put it in and waited for an hour. Went out to start it and it started right up! Went out the drive and it stalled again. Changed MAF sensor started right up! Next day coming home from work and it stalled again (60mph) very dangerous! Called for new part and replaced it.... started right up again, drove for a day and a half. stalled again. Now I am changing PVC valve and Crank Shaft Sensor.... will see!

Update from Dec 30, 2011: Since my last post we still haven't found the problem but one temporary fix is that we found that if we would reset the codes it would start everytime. So I bought a code reader and when it stalls while driving I reset codes and starts right up! Now.... my senario is that that it only stalls when I drive at a constant speed (say on the highway) going around town up to store and back say... it never stalls....drives great matter of fact and it always has 12yrs. So were still searching for problem but it's been a good temporay fix so I don't get stranded!!!

My car won't turn on sometimes. It will start at the grocery store but I get stranded at the vet office. The wife complains but she does come and picks me up. This attitude my old chevy has been displaying recently is becoming a real pain in the butt! I have switched keys and that worked for a time, but depending on how it is feeling it may or may not start the next day or the next trip. Who knows. Only the car knows because the mechanics can't figure it out...yet! I have a feeling it is not the ignition switch nor a starter. It is probably a security electrical issue and not for sure where one should spend $$$ attempting to figure it out. I'm thinking about taking it to Carmax and getting my $2,500 for it and going and buying a bicycle since I only live two miles from work!

I have some like I said some good days my car start up with out a problem but other times it takes a while for it to start up. It could take like 5mins to hours before it starts. I tried so many things as opening the car door it starts some times, closing the car door works some times, Lock n unlock with key alarm helps sometimes, putting car in neutral every now n then, Holding the parking break might help Ive tried like everything and its weird how it starts up @ different times doing different things. Why is it doing this.

Okay.. I have a 2000 impala LS... This car has caused me troubles since day 1. First, had to replace the engine with 01 monte carlo ss engine. Here is the problem... I changed my battery with my dad because he needed it back, so I used a different one, battery was in another car of ours " it works fine ".. Left the house did some things, came home for awhile and left again to go about 30 minutes away.. The car seemed like it didnt wanna start at first but it did.. I left, " the whole way thinking to myself my car is gonne break soon " And it did " Left the place that I arrived at earlier, go to my car and it doesnt start, it does NOTHING... radio,lights,noices,dash all come on, but no crank , no nothing ?? Checked the battery for loose cabes since I just changed it, battery is FINE.. So, Jumped the car, still NOTHING....Kinda think its something with the anti- theft bypass thing but my security light does NOT come on ?? Dad got under the car after engaging the key in the igntion to try to start it w/ a screw driver.. Runs for 2 seconds and kills itsself... This is weird, So with no security light we dont think thats the problem... Knocked on the starter a few times and nothing so its not the starter either... Can someone PLEASE help me.. ?!?!

to be honest i think impala model is really not bad, just came out with kind of a lot of factory defects. but they are very comfortable to drive, nice body shape and kind of fast....but like i say if you used it you should treat it with care because if you don't those factory defects will show faster. i know its kind of a pain in the ass when this problems start showing but really the problem and the pain in the ass and BIG HEADACHES of all this is to really find a good truthful honest mechanic............ ohhhhhhhhhh really something i know for sure DEALERS SERVICERS just make your time and money go to the dumpster

My 2000 impala has been having problems with running. It will start and then once you put your foot on the gas the car just shuts off. I was driving to work and the car just shut off in the middle of the road. I called AAA and they towed it to my house then the next day my husband changed the fuel pump, and filter but the problem keeps happening I really don't know what the problem is with this stupid car its driving me crazy. please if someone has any idea what's the matter with it and what I can do to fix the problem please let me know. Thank you.

I bought a 2000 impala from a local auction. While driving the car it started skipping and would not take the gas, then finally cut off. I let it set for a while then it started back up and did the same thing. I took it to a local mechanic and he change my wires, spark plugs, and some sensors, It drove fine for about 2 weeks then stated shutting off while driving, and finally wouldn't start at all. I had it check out again and found out the car is not firing at all when trying to crank it. I read some other complaints and wanted to know if the BCM what cause a car to not fire or would it be the computer on the car. Please someone help i am a student without much money and don't want to put to much more in this if it is a piece of junk.

About every two weeks, and this has been happening since May09 when I bought this car from a Used car lot, my car won't start. I replaced the battery, starter and alternator. I'm now having the ignition lock cylinder replaced for $500. NO ONE has been able to diagnose the problem. They say "unless we have it when it's happening, there's not a lot we can do but guestimate as to what the problem is". I move my gear shift from P to D and back several times, turn the car on and off, several times, and usually within 10 minutes it will start. When it won't start, there is no clicking, no nothing. Everything works within the car, so it's not a battery problem. I just wish someone could say..it is definately this........

Two weeks after I purchased my used 2000 Impala, it wouldn't start. Tow truck came and jump started it fine. Guy said battery was original, suggested replacing it. I did, and a week later, the car won't start again. Took it to a shop, they tested battery, alternator and said 'possibly' is the starter or ignition switch. They replaced the starter and within a few weeks, car won't start again. The thing is, a jump will get it started every time. So, I've purchased a self contained jump starter in case I'm stranded. It's going to the shop again tomorrow for a diagnostic check and we'll see what they say. I've contacted the dealer I bought this from and they said let them know what diagnostic check comes back with, but they made no promises to reimburse me for anything. I've seen several comments about the security key, so maybe I'll go get a key made at Lowes too. This is really annoying as it sounds like no one has truly figured out what the real problem is. Maybe this model is a Lemon?? It's left quite a sour taste in my mouth!

This car stopped running, and was dogging out the day before I got paid, so I had it "fixed" they replaced the "mass flow" sensor, although the code it read out was the osm sensor. It is the sensor to the right hand side of the intake manifold, on the top. This was replaced three times, and my car seems to run fine for any mechanic I take it to, (I think my car is demonic) but will not run at all for me, for the first couple of times, it would run fine for my boyfriend and his friends, and last time it broke down, some guy with a mullet got it started and it ran fine for about 20 miles, then shat out again. My friend thinks it might be the fuel pump, ( I can't afford that) and I say maybe the air filter. Any help at all on what this might be, or if you had it happen too would be great!

I have been having this Security Light problem for some time now and I am hesitant to let anyone fix it because no one knows what the problem is. Or at least I haven't seen a valid solution yet. I would like to get rid of the Passlock or disable it. If someone knows how please let me know. I am tired of waiting 10 minutes or more to get the car to start whenever the security light feels like coming on. Also., all the star and moon alignment methods to get the car to star are worthless. My car has about 167K miles on it now (Im gonna run the thing into the ground) and the issue started at about 134K. Does that passlock bypass I read about work? Is the method the same for a 200) Implala? I don't want to jack up my car's electrical system.
