Starting problems 2000 impala

Hey everyone. I have a 2000 Chevy impala LS with a 3.8 engine. about 2 weeks ago my car would not start. i turned the key and all the electrical came on like normal but the engine would not turn over and the starter didnt sound like it was trying to turnover. so i replaced the starter last week and it worked fine for a week until yesterday it started doing the same thing

Any suggestion of tips?

First check the connections on the starter to make sure nothing has come loose.

The ground path for the starter is through the engine block and starter case. If the negative cable attachment or the area the starter mounts is dirty or has paint on it you will not get a good ground. It will cause slow cranking, no cranking and a lot of frustration.

Starter on this car is operated by CRANK relay in underhood fuse block. you need to monitor the ppl wire to the starter and verify power in the crank position. If you have no power, you possibly have a bad crank relay, poor connection at underhood fuse block, or even a faulty PCM. The PCM is what grounds the control side of the relay to put power through the relay to the starter. Also, if the PCM is not receiving the signal from the ignition switch indicating crank request, the PCM will not activate the starter relay. This is assuming you've checked all the basics and you know for sure you don't have any theft deterrent issues. If you know someone with a good scanner, you can monitor all the inputs and commands for this circuit.

As a former computer tech who had to occasionally wear a grounding strap durring the winter weeks in Florida (when a cold front brought in cool dry air to the state and long before these artic blasts that have killed alll vegitation in the state). Has anyone thought that the computer chip in our new ignition keys being fried by static electricity from a spark when we stick the key in the car door (not everyone uses the auto locks). I wonder if a dead key would cause the issues he is having.

I know nothing about OBD computer controlled cars as I only know how to operate a screw driver.

Is there a possibility that my stock security system could be preventing it from starting?

hey guys I am having the same problem with my 00 impala, it has 172k on it, and the 3.4L, having the same issues as the guy above with the car not starting, whenever it feels like it, but I have also actually had the car start a few times, and the guages do not work at all, then when I shut off the car, it will not start again for a while. I have replaced the alt, batt, ignition switch, not the ignition cylinder though, starter and I have even done the "bypass" procedure for the passlock system. The problem is extremely weird, I have had it hooked up to scanners, but none of them show anything, I have been told that the scanner would have to be hooked up to it when the problem is actually happening (which is impossible, how am I supposed to get a scanner to hook up to it when its not running without buying one of my own????) anyways this is a huge problem with GM and I would really just like to find a cheap, or free fix that would end this B.S. Please anyone that has any ideas let me know, I have tried everything it seems like. and the dealer wants to charge me $600 for a POSSIBLE solution, might work, might not.

tmbrockett, from what I have read up and been researching for myself it seems to be something most likely with the passlock sensor. Their is really no solution to these problems without bringing it into GM, which realy sucks. anyone out there that knows help us!!!!!

hey I found out how to fix it, replace your ignition cylinder, the inside where the key slides into the ignition, not the back plastic ignition switch, GM wants 225 for the part, but I found the exact same thing on ebay brand new for $89 and you actually put the tumblers in yourself so you can keep the same key. I called around to a bunch of GM dealers and their was one guy that told me how to fix it and give me a price quote. 225 for the part and 115 per hour to put it in, but I will put it in myself. I am not quite sure if it needs to be coded in afterwards, but I don't care i am certain it will fix my problems. I will let you guys know in a few days when I get it all back together if it worked. Here's the link for the ebay auction. its a great company, they have phone support and it comes with instructions, so if you have any questions they can walk you through it over the phone. It comes with everything shown in the picture and instructions.

in my opinion its better to fix the problem for under 90 bucks, than to try and jimmy rig it around the problem. I did the bypass passlock system procedures, but that still never worked for me, it worked for like a month then went back into it and if you bypass the passlock your security light will always be on, not a good thing if your trying to sell your car, or dont want to get it stolen, then people know your security system is screwed up.

damn, worked for a few days, now its doing it again, so that must not have been the problem, im not sure, maybe I have to have it "relearn the key", since its a new passlock and ignition cylinder. tmbrockett do you have a stock radio or aftermakret? I am trying to figure out what links all these problems together.... what else do you have thats not original equipment?? if anything

ok because I also have an aftermarket stereo and I am trying to figure out what is actually causing these problems because it never did this when I had the stock stereo installed.

Yeah I unplugged my subs too but it still didnt start a few times so I know its not the subs, but the deck is what im thinking it could be, because the passlock system actaully runs through your stock head unit. But I am not sure.... I ordered a BCM, but I don't think its really even worth trying and paying the dealer 100 bucks to get them to code it in.... no one says that replacing the BCM has worked permanently for them.....

Dear GOD! Thanks for this post, I can tell you with all assurance, i'll never be trading my '63 up for one of THESE horrors!

I've lived the "GM Experience" already with a 1994 Cadillac that never wanted to start ... I almost landed in jail after throttling my salesman within an inch of his life!

Hope you guys find a solution.

This works until the next time

In the year I bought my Impala 2000 I came across this very issue, turn key... nothing, so I figured like all problems with computers, reboot them. So I unplugeg positive termial from battery and reattached it and my car started, plain, simple and no cost.
