2002 Impala LS No Start

[monteheeren]

My Impala LS will not start sometimes. Its only failed twice. Have plenty of battery, just nothing when you turn the switch. Like the Security is preventing me from starting the car. Been reading on this forum trying to figure out what my game plan is. Car is starting again, but I do not trust it.

Car: 2002 Impala LS 3.8 engine, 60,000 miles, new starter, new front wheel bearings. NO Security light is on. Although, the Traction Active light does come on sometimes. Thats why I replaced the front wheel bearings. The battery is good, and all connections are clean. There are no codes set from my hand held scanner. All fuses look good.

Do you think it is the PassLock or BCM or something else?

Does anyone know where I should start?

Try using the spare key!

[monteheeren]

Already tried that.

Need to see if you are getting a spark, during a Non start issue!

Getting code P1626 theft deterrent system.

Make sure the key is fully seated in the ignition switch cylinder, if the chip in the key is sloppy get a new key.

Some local hardware stores can do encryepted keys for half the price.

Sounds to me that you BCM is malfunctioning. Try this easy fast way to try and fix your problem.

Follow these steps completely of your car will not fix itself.

Put the key in the ignition. Try and start the car. If you see the security light and the vehicle will not start you have a BCM thats lost the programming. It also controls the anti-theft light too. Follow below:

Turn the key ON and turn OFF
REMOVE the key from the iginition.
RE-INSERT the key and turn the ignition on.
Leave it on for 30 minutes.
DO NOT use the windows, play the radio, or run anything during this time.
Do not shut the key off before the 30 minute time lapse or you may have to reprogram it again.

Shut the ignition off, REMOVE the key, and reinsert it. This readys the BCM for the start sequence.

START the car normally. Hopefully this fixed your problem. If not trust your car to the local chevy dealer.

I first had the Passlock problem over a year ago. I did the "turn key to ON and wait 10 mins til Security light stops flashing" thing a number of times. Then my key also started getting stuck in the ignition, so I had the tumbler replaced. No Passlock problems after that! Until one day last month, the dreaded Security light came on while driving and, soon enough, was dealing with the won't start issue again.

I looked anew for solutions and came across the following (maybe on this site, but I can't recall) and it has been working so far (six weeks). The light has come on a few times while driving, but using the following steps every time I start the car, I have not had the "won't start" problem. I do not know if this a real solution, or just coincidence that my car has started every time. But I'll continue to do it until it's proven not to work:

Every time you drive:

1. Get in the car and close the door.
2. Put the key in the ignition and turn one click to the right, to “ACC” Wait two or three seconds until the (faint) electronics noises stop
3. Turn the key to the “ON” position (do NOT turn all the way to “START”)
4. Wait 5+ seconds for the bells and other noises to stop
5. Turn the key to Start.
6. (Assuming the engine started), put on your seat belt and off you go...

Like I said, this is working for me so far. I hope it is a solution, not just a coincidence
