Question about 2004 Pontiac Grand Prix

Open Question

My 04 Pontiac Grand Prix GTP with supercharger is giving me all types of different codes but the most frequent one is the Charging System Failure light, then it wouldnt start and made a loud clicking noise & I had to get a boost off. Ive taken it to AutoZone & gotten my battery & alternator tested but both were good, but now something was smoking under my hood this morning, but my car started. Can anyone tell me what the problem could be?

SOURCE: Anti-theft code 1995 Pontiac Grand Prix

DO a google search for Radio lock codes with you make model vehicle,, for 7$ you can get it,,here is what I found for a 2000 gp..
1. Press and hold presets 2 and 3 for about 7 seconds until you get 3 digits on your display. This is the first 3 digits you will need, so write them down.

2. Press the AM/FM button to get the last 3 of the 6 numbers you will need. You only have 5 seconds to do this. If you wait too long before pressing the AM/FM button, the display will go back to LOC. If this is the case, just start over at step 1.

3. Call 1-800-537-5140, press 2 for Pontiac, press 620529 and hit the # key. The computerized voice will ask you for your 6 digit code you have written down. Enter that and press the * key. He will then give you your unlock code, and the option to get additional codes. The first one worked for me so do not worry about the additional ones.

4. Set the code into your radio by pressing the hour set button on your radio until it corresponds with the first 2 digits of your code, then press the minute set button until the last 2 digits of your code are entered. Immediately press the AM/FM button once the correct code is entered and the code SEC or "secured" will be displayed. This part of the procedure is outlined in your owners manual.

5. If you want, you can change your code so you will not forget it, or get rid of the theftlock all together. These procedures are outlined in your owners manual, read it if you would like to change these values.

6. turn on the power to your radio and enjoy.


Hints:

- The first 3 and the last 3 digits were the same on my radio. (for example first 3 were 123 and last 3 were 123) First I thought I was doing something wrong when the display wasn't changing, but I wasn't. Just to let you know it is a possibility.

- The dealer code 620529 is an actual dealer. If GM finds out that this code was leaked to the public, they will remove it from their system. If the dealer code does not work when you phone the 1-800 number, you can search for a new dealer code on the internet somewhere. If this does happen, PM me and I will try to find one that works for you.

SOURCE: 04 pontiac grand prix wont start.

first remove the battery and take it to a auto parts place and have them check it. move on from there. if the battery is good the do a starter draw test. take a meter and hook it to your battery. now have someone try and start the car. if the voltage on the battery drops from 12.8 to below 9 volts then the starter is bad. if the voltage doesnt drop much at all then its prolly the solenoid both of which require starter replacement since most solenoids are on starters. if still nothing then check ignition switch. but before anything else ensure vehicle is in park. if it is in part use a meter to test neutral safety switch.

SOURCE: charging system failure

Hello! The problem you are experiencing is most likely due to a fautly or malfunctioning alternator. You can take the car to any major auto parts store, and they can do a FREE charging system test which will tell you if your alternator is operating (and charging the battery) properly, as well as if your battery is accepting the incoming charge from the alternator.

Hope this helps and good luck!

2000 Grand Prix GTP supercharger fluctuates when accelerating


There is no wastegate.

Change the spark plugs and pay special attention to the plug on bank 3. Look for physical damage on the electrode...cracked, bent etc.
Use Autolite 605's copper core gapped to .055" and NEVER run less than 92 octane.

Can I take a super charger out of a Grand Prix GTP and fit it on my Grand Prix GT 3.8L V6?


Well, the short answer is "yes". But - it isn't nearly as simple as just bolting the supercharger onto the intake and VOILA!, now you're supercharged. The procedure that you're inquiring about is commonly referred to as a "top swap", and there are numerous parts you will need for both engine as well as the transmission. Why the transmission? Because the GT and GTP use different gear ratios and the GTP has a 4T65HD as opposed to the 4T65E that is in the SE/GT. You will also need to have the PCM reprogrammed to accomodate all of these changes.

HERE is a great website that has a ton of very useful information, regarding this and many other Grand Prix topics.

Hope this helps and thanks for using FixYa!
