What causes hard start when engine is cold?
Cold batteries simply don’t produce the same amount of power as warm batteries, and this effect can lead to starting issues. When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. This means it’s more difficult to pump through the engine block, placing additional strain on the battery.

If it starts up you likely have a fuel system problem, but if it doesn’t start, your ignition module or coil is likely almost finished.
