I have 2001 C4S coupe, manual trans. this morning it was 3 degrees cold. I tried to start the car but it was a hard start. It took about 2 minutes of trying till the engine fired. there was black smoke that came out. when the car started and warmed up there was no problem engine was running smooth. I haven't used the car for about 3 days. It has 1/2 full fuel tank. this was the first time it happened but it wasn't this cold as well. Has anyone have this problem on cold weather start? could it be a frozen fuel line? I always use 93 octane ( west Virginia). If this was a fuel line freeze is there anything that you can add to the fuel to prevent freeze?TIA

If the gas did not freeze, could it be there was some water on the fuel line? Today it was 20 deg no problem with starting the car. Has anyone have this problem in the past or this winter? Need help, worried that I might do damage to the engine

Yes, moisture in the fuel can cause gas line freeze. Most good gasoline suppliers add some deicer (methanol) to there fuel shipments in the winter. If that is a concern then buy and use some HEET Gas-Line Antifreeze and Water Remover. It will not hurt anything and it will remove water/moisture from your fuel.

Loren is a wise man. A few months after purchasing a new BMW, I had an episode where it started and sputtered but would not run well enough to leave the driveway on a near zero degree night. One bottle af gas dryer and all was well 5 minutes later.

I worked at a gas station in high school...anyone else here remember water paste? :D
