Make sure the plug in insecurely. Also, its possible that the engine is flooded if while turning the engine over, you did not hold the pedal at Wide Open Throttle. During next start up, hold the petal at WOT and see if that will get the car started.
Yep.
Capacitor
It actually does a little bit, but not as much as being turned on.
It depends on how the pump was turned off. Was it unplugged? Was the air ride switch turned off? If your air springs are working properly, then all you have to do is make sure the switch is on and the compressor is plugged in. Start the car, close the door, and wait for the system to inflate.
Yes and sometimes it needs to be turned off or unplugged and restarted to solve the problem
Assuming the question was meant to be "Can you safelyleave things plugged into the cigarette lighter of a car if they're turned off?" - the answer is yes.
Yes, a radio will still use a small amount of electricity when plugged in but not turned on. This is because even in standby mode, the radio is still drawing power to maintain the clock or other settings.
No, an electric can opener does not use electricity when it is not in use, provided it is unplugged from the power outlet. If it remains plugged in but is not turned on, it typically does not consume significant energy, as most modern appliances have low standby power consumption. However, to ensure no energy usage at all, it is best to unplug the device when not in use.
A toaster is considered a closed circuit when it is plugged in and turned on, allowing electricity to flow through the heating elements to generate heat. When the toaster is unplugged or the lever is not engaged, the circuit is open, stopping the flow of electricity. Thus, the operational state of the toaster determines whether it functions as a closed or open circuit.
Bulbs are things that are plugged into light sockets, and they light up when the electricity is turned on.
they only use electricity when an appliance is plugged in and switched on
Yes. Not as much but if it is plugged in it will still use some power.
