What does it mean when your car takes a long time to start?
A: Possible causes: a marginal battery, a poor connection in the starting circuit or starter, a charging-system problem, or the battery is being drained while the car’s parked. If the slow cranking occurs after driving (engine hot), it’s likely a faulty starter or poor charging.
Why does my car not start when it’s hot?
If there’s nothing wrong with your coolant levels, your motor oil, or your battery, and your car still won’t start in hot weather, it could indicate a deeper issue with your engine. Your coolant temperature sensor might be broken, for instance, which means that the engine will “think” it’s hotter than it is.
When to run the fuel pump before cranking the engine?
Some systems will run the fuel pump for a short period when the drivers door is opened or when the key is turned to the ignition stop before being turned to crank. If this isn’t happening for some reason, you may be having to wait until the fuel pump provides enough pressure at the fuel rail to start the vehicle. My vote is for the injectors.
Can you start a car when the engine is warm?
In about 20% of warm engine scenarios it doesn’t need this treatment but it never occurs when the engine is cold. Through research I’ve heard about something called ‘vapor lock’ which appears to describe this – the remedy (drop the accelerator at the same time of killing the engine) seems to resolve the issue for the next startup.
Can a Ford Focus start when the engine is warm?
I have a Ford Focus MKII (British market) with the 1.8 Duratec Engine that is very hesitant starting when warm. The starter cranks powerfully but the car will only come to life when pumping the accelerator, sometimes it’ll start but at very low revs (until I pump the accelerator).
Why does my car not start when it’s Hot?
This could be due to a few things related to the fuel supply line, including: The reason why this happens only for hot starts is because the fuel is more likely to vaporize as temperature increases. In order to avoid vaporization problems the fuel lines are expected to be pressurized during a hot start.
