Why engine hard to start when cold?

When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. In the rare event that there’s moisture in the fuel lines, this can freeze and cause a fuel blockage, meaning the engine won’t start. This is particularly common in the fuel lines, which are thin and easily blocked by ice.

Can a cold engine start a Harley Davidson?

After waiting say 15 or 20 minutes, it starts fine. It doesnt do this all the time and never when I first start with a cold engine. Only after I have been riding awhile sometimes it will start right away but seems after the 4th or 5th stop nothing, it just cranks like it not getting any gas or not firing.

Why does my car starter not crank when it’s Hot?

If your starter easily cranks a cold engine, but “drags” or cranks very slowly when hot, there may be a “heat soak” problem. Before you condemn the starter as bad, you should perform a system diagnosis of the battery, cables and starter.
