Its probably a short some place in the wiring on your turn signal switch ie the ground is shorting out your positive making it pulling to much to blow a fuse.----- If the fuse directly blows as soon as you turn the ignition then , ignition switch wiring's also need to be inspected.-------- But if the fuse is blowing when you operate the turn signal lights, then turn signal switch and its wiring needs to be inspected, there is definite short.--------- Getting this checked will help.Thanks.Helpmech.

start the engine and connect a tester to measure voltage between the terminals of the battery you should read more than 13.5 volts. If it's under that (ex. 12v) then the alternator doesn't work no matter if it's new if it's under 13.5 volts it's ruined. Assuming that the alternator regulator it's incorporated in the alternator cause if it has an external regulator, that's where the problem is.

This is a very common problem on GM vehicles. The car's key, ignition, and TDM (theft deterrent module) are not communicating properly. This can be a very expensive fix, but is rather easy and inexpensive to bypass. Look at this link for info on how to fix this. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Attached to fuel sending unit in gas tank.

Fuel pressure should be between 41 and 47 psi.

check your fuel pressure regulator its location should be on the fuel rail.Pull vacuum hose off regulator if fuel drains out of it then the diaphram is bad. Hope this helps!!

Your symptons sound very similar to a security failure. The year vehicle is also notorious for this system failing. Do you notice a light on the dash that says SECURITY when this happens? If so, check out this link. http://vatspasslockpasskeysecurityhelp.yolasite.com/

CAN YOU HEAR THE FUEL PUMP RUN WHEN YOU TURN THE KEY?? if so then install a pressure guage and see if the pressure drops when you try to start the car, your problem is fuel , either a pump or no voltage getting to pump

On the end tank of the radiator,pass side,there is a sensor for that.It's not a float or anything ,it's
electronic,SOMTIMES you can just tap on them and they come to life ,for awhile.
If not the sensor is easy to change,seemed like they are like 30 bucks tho.

LOOK INSIDE THE TRUNK AREA.

Cars should be service regularly and will reward you with good MPG and long life.
Filters / plugs / oil etc should be changed at least per manufacturers mileage or time.

are you talking about a milky look to your oil? unless there is standing water around the pcv then no. there is a coolant leak

No there should be no free play in the balancer. There is a rubber ring in the middle of two steel sections on that balancer that will rot out and cause a knockign issue and free play as you describe.

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car

1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shuting down while running, im sorry i have no quick fix...

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page......... They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks.

----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

Check fuel pressure,spark.If no spark possible crank sensor or ignition module.If no fuel pressure tap the bottom of the fuel tank with a mallet while someone is cranking the vehicle if it starts then you will need a fuel pump.Also if you have spark and fuel but the engine feels like it bucking while turning over,take a hair dryer and heat the coils up.you may have a bad coil pack.After they get warmed it night then start as the coil resistance changes.

Contact your local GM - Buick dealership give service dept vin # located on title ,registration,or lower drivers side under windshield front dash area.If it's possible they should be able to give procedure or retrieve original code.Also if you have original manual & paper work sometimes code is printed or hand written
Good Luck
