Have u tried cleaning the inside of the of the sensor with CRC brand MAF cleaner?, many times the problem is a tiny piece of dirt on the sensors little wire heated element that causes the signal to be confused and results in stalling and loss of power

I have found three other components, The blower motor resistor which is directly below the windshield and is held in by three 7mm bolts and the 4 wire connector that plugs into it; the relay which is a black box to the passenger side of the car; and the switch on the dash. They are al $6 to $20 parts. and I would start in the same order

It's the fan connector.

Open drivers door. Look at the side of dash by the headlight switch for two black round thing and turn them to release the face plate around the headlight switch and you will find what you are looking for.

sounds like a fuse. two places to look. In the car. Under the hood.

check the ground wire blk/brown

Get a spray can of either (starting fluid) While someone cranks the engine spray SMALL amounts of the fluid into the air intake. I stress small amounts a little at a time so you don't blow the engine. If the engine does start I would check to see if you have water in the fuel system first and if not I would check the fuel pump pressure.

The heater conrol has to be removed first but not all the way just out far enought to get ot the back of it with the control pulled out the 1/4 in headed screws can be removed and the switch after the knob has been removed can be taken off the back of the panel. he switches that have failed most of the time the plug that pluggs into the switch also fails and it'll need to be replaced also. this pig tail is a common replace ment part and your parts store shoul have it to. and but it when you buy the switch so you can check it and see that it fits. Now also but the heater blower motor as it's drawing too much power and it'll burn out the new switch too and if it wren't bad the switch would'of never failed.

There is a u-joint inside the steering column if you have tilt wheel. Which I don't think that I have ever seen a steering column get loose if there is not tilt wheel. If there is not tilt wheel then there are two bolts that hold the steering column up against the bottom side of the dash. You will just need to tighten these two bolts. If you do have tilt wheel, then it is going to require taking the steering column out and replacing the u-joint in the steering column.

dead battery or bad battery cable connections clean the connections and jump the battery should start.

disconnect the battery wait five minutes reconnect the battery let the computer reset this should put that check engine light out.

YOU HAVE A BAD HUB BEARING

There should only be 2 bolts and to wires going to the starter.

If you can't get it of it may be jammed inside the motor.

Hope this helped. Please rate if it did.
Good Luck

Please see my tip at http://www.fixya.com/cars/r5925550-dead_battery_troubleshooting . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

I worked on Buick's for 18 years and this was a bad design. unfortunately the magnet snaps in from the back side of the cam gear their is no cheating this one. My experiences with these was that by the time the plastic retainer on the magnet got brittle enough to cause problems with the magnet the timing chain was worn out any way, so if is worth fixing just replace the timing chain and gears and your magnet Good Luck
