    My 01 pont grand am gt has been cutting out too. It is when I slow down when I come to a stop sign. It dies, but starts back up. This was after getting the head gaskets replaced, so my batter was probably removed during the repars.

For the first problem up top, put a battery chrager on your new battery for about 15 to 30 minutes and leave the car alone. this resets the computer. my car also did this. TRY IT!!

Usually if you replace a battery, you have to re-flash the C.P.U..

The problem is that when you take the battery out and replace it, the stereo, alarm, presets for seats, etc, get deleted. You need to go to a Chevy dealer or a shop that can flash the C.P.U. to fix the problem.

Sorry, but that's the "ONLY" fix for your problem.

How to reset computer on 2007 Chevrolet up-lander after battery change


I am going to take a wild guess and say that the security light was on steady before you decided to change the battery. I am also going to guess that it had been on for a while and you never looked into why it was on because the vehicle was starting an driving just fine.

What likely happened is there was a problem with the ant-theft system. The problem was likely minor and the system went into a limp mode of sorts allowing you to continue to drive and start the vehicle with no issues.

the problem with these limp modes is if the battery is disconnected the system shuts the vehicle down as no longer remembers that the previous problem happened when the vehicle was being operated normally. The system now thinks the vehicle is being stolen and is shutting down the vehicle.

You best bet is to tow it to a reputable shop that has experience with these systems to have the problem diagnosed, repaired and relearn the anti theft system.

I have a 2004 dodge Durango hemi 4wheel drive I'm losing power to the fuel pump I turn the car on three times the third time it will stay running for like ten seconds then the vehicle shuts its self down...


you could have a few problems,check the "auto shut down relay " that is in the pdc ( fuse box) under the hood several of them are the same so substitute the A/C relay and see if that works, Or you might have an issue with the SKIM module that reads the key if it does not read a programed key it will run for a few seconds and shut the fuel off to prevent theft-is there a little red light on in the dash? thats a security light for the theft system

Transponder keys


I would check the circuits at the key switch first. The anti-theft should only affect the starter and engine, not things like power windows.

The car motor just quits all the gages stay normal except the oil gage.


Alot of the time, the Anti theft that came stock on your vehicle can shut the car down. When the system starts to get worn down, the car tends to mis communicate and shut itself off. This is to prevent theft. #1. Is there a light somewhere on the dash when this happens? Should say security or anti theft. If you see this light, then this is 100% your problem. This link explains the situation and offers some proven DO IT YOURSELF solutions. Hope this helps. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Chevy cavalier z24 theft system light on


This is a easy fix. Lucky just follow the procedure and your car will start. This is a theft system shut down.
The procedure is. Disconnect battery for a minimum of 30 seconds. ( one post is OK. )
Reconnect battery and get in the car and start as usual 1 time only. When it starts and stops letthe key just return to run position as if it was running. Do not shut it off and if you do you must stert the procedure all over again. i usually put on the emergency brake before i start and that shuts of the driving lights etc.
Just leave the key in on running position and go have a coffee. it takes 15 to 20 minutes for the car to recycle the system. When you come back to the car the flashing theft light will either be off or solid.
Try to start again. If it doesn't go shut it off and turn back on and start as usual. It will start and run and stay running.
The reason you have this problem is something electronic was disconnected whe the battery was hooked up. always disconnect the battery before you touch anything electronic and you will not have this problem.
