If you're using the correct oil viscosity, have a good battery and good spark plugs, you shouldn't need an engine heater.

Circuit Description
Moving the ignition switch to the START position sends a 12 volt signal to the powertrain control module (PCM) Ignition Crank Sense. The PCM verifies that the transmission is in the PARK or NEUTRAL position. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows battery positive voltage to the starter solenoid S terminal.

Bad battery cables or loose cables could do thatI could not even boost my car so I towed it to a garage. They put new set of cables on and works good now.

I have a 1997 buick la sabre and i need to locate and replace the throttle sensor and i do not know where it is located and how to change it...can anyone help?

The throttle position sensor is on the throttle body, exactly opposite the throttle cable. Locate the throttle cable, and look on the opposite side of that aluminum housing that the big black air intake tube attaches to.

My Electic Front Drivers set Will not go Back and Forth It ia a 1991 Buick La Sabre

First you'll need to determine if the fuse and / or relay is good. If so, then check the seat switch by ' hotwiring ' ( running a positive wire from the battery to the positive side of the switch ) . if the hotwire worked, your switch is bad - if not then you may have a bad seat motor or corroded connection. You may need to remove the seat from the vehicle to further test connections and / or run your hotwire to the positive side of the motor, which may be difficult at best. I'd check the fuses first, then relay, the call your local shop since everything else can get complicated.
Good luck!

I have a 94 buick la sabre stalls when warm has spark no fuel pressure also loses power to power windows and locks,when car sits it will start and windows and locks will also work.runs a little while and...

Sounds like you a loose 12V connection at the relay box.Locate the relay box and when the engine is running wriggle the wiring harness or shake the relay bow and see if that's when the engine stalls. You may even have a bad / loose ground to the relays.
