In Cold weather my 2001 Chevy Cavalier died frequently?

check the condition of the battery with a load test. batteries are prone to failure in cold weather

If you're saying you may have ice stuck in the hose that goes into your gas tank, yes Heet is fine. Heet is just fuel additive that gets rid of water and keep gas from freezing in the lines. If ice is out of the question, I'd have your tank dropped, might have something that died in there ie. mouse that made a home in there?

A few ,tune up,fuel filter,air filter,

Trace the power source from fuse to relay etc and make sure pump is working. if all checks out then check pump working and for preasue at engine. you may have a dammaged fuel line from the tank which would also cause the same problem

I would say fuel pump but u should try cleaning throttle body 1st its easy takd ya 30min and only like 8$ for cleaner u can watch how to videos on you tube

Try adding gas line antifreeze to your fuel. If you have water in the gas, this will clear it up. Water in the gas line can turn to slush or even ice when the temperature dips below freezing, causing reduced power because of reduced fuel flow.

You may have the same problem my Wifes car has right now- ice in the fuel line.

Dump a can of DryGas (or "Heet") in the tank, and after about an hour, start your truck. Let it run for 15 minutes or so (restart if it stalls) - if it will not run that long try moving your truck into a warm garage, let it sit for about an hour, and try again.

The DryGas does not perform miracles, and takes time, especially in the bitter cold as of late.

Fuel line icing is usually caused by allowing your vehicle to run nearly empty, and then refueling in cold weather. This causes condensation in the gas tank, which freezes in the gas lines.

I have repeated this mantra to my Wife for nearly our entire 27 years of marraige, but she still will run her tank nearly dry before getting gas, even though it has so far cost us two replacement gas tanks, more than a couple gas tank leak patches (the other problem with running low all the time is rotting out your tank!), and uncounted winter car starting problems. Please help me break the trend!

it sounds like a dirty throttle body. Just spray clean with throttle body cleaner. Or it could be a plugged air filter...not getting enough air. Or possible fuel filter needs to be changed.

have you had water undere the hood? splashing thru rain? it sounds like a bad throttle position sensor, possably some water in it. now that it is cold, it freezes up and makes reading the throttle difficult

Could be failed fuel pump. Disconnect fuel line at engine and turn over a couple times having something to catch gas in. If electric pump don't turn over engine, just turn key to run position for a few seconds. Maybe clogged fuel filter or faulty pump if no gas shows. Change fuel filter and try again. If none, change pump.
