What causes hot start issues?
This is due to one or more of the following factors: Bad cell/internal connection inside the battery. Bad connection to a battery terminal, the starter solenoid (either side) or the starter. Starter internally shorted when hot.
What causes a car to overheat in the winter?
Overheating occurs in winter due to a fault that occurs in a vehicle’s cooling system. Most common faults are coolant leaks or a blocked thermostat. Coolant passes through the engine’s coolant passages, as it does the heat that is produced by friction and combustion, in the engine and is transferred into the coolant.
Why does my Car start slow in the winter?
Slow Battery Cold start car problems are the most common when starting automotive in winter. Extreme cold can affect the battery performance too. It produces electrons through chemical reactions, but the process slows down in low temperature. As a result, it generates fewer electrons and supplies less than sufficient energy to the starter.
What causes a hard start when the engine is warm?
Leaking fuel injectors cause fuel to leak into the combustion chamber. That often doesn’t cause problems on a cold start because most of that fuel has evaporated between the last shut down and the cold start. But leaking fuel can cause an extended crank and hard start when hot and then a rough idle for a while when the engine is warm.

What causes a truck to not start when cold?
Truck will not start when cold unless given a shot of starting fluid. Replaced fuel pump in tank. Still have the same problem. Truck runs fine, plenty of power, no symptoms, then it becomes harder to start. Each successive start requires more turns of the engine, then finally it won’ start after twenty or so revolutions.
