Default 97 Bonneville won't start

Got a 97 that when its cold weather it just won't start. warm weather it cranks right up.
It'* not the battery,motor turns over just fine,only thing i have put on the car is a crank sensor back during the summer?could i possibly have bent 1 of the tabs behind the harmonic balancer>???any ideas?

Check for spark, Suspect coils.

If you bent a tooth back, you car would not start at all(Personal experience).

I also think checking the coils should be at the top of the list. Here'* a how-to article.

How old are the plugs & wires?

plugs are new..wires look ok?will be putting new 1'* on,also note that when it finally does crank,after turning the motor over and over many times,it finally starts but at a rough idle,then all of a sudden it just clears right up....if it was the coil why only when its cold./

You need a hotter spark to fire the richer mixture. My 89 was doing the same thing.

What kind of gas are you using? Are you using a winter blend fuel?
