No. You unplug the block heater BEFORE you start the truck.
People leave their diesel trucks running because they think it is better. It is a truck with no spark plugs.
Weak fuel pump? Bad fuel pump? Plugged fuel filter? Plugged air filter? Bad ignition coil? plugged catalytic converter?
I've got a 2006 F-350 KR and I do it all the time ! I don't believe it is connected to the truck circuit ! I wouldn't leave it on there after the truck has started ! ! ! !
I usually leave it plugged in if I can, because why not keep your battery charged?
It really is not safe to leave a AC adapter plugged in. If not using I would unplug it.
No - you do not need to have the truck running.
Plugged fuel/air filter? Plugged catalytic converter? Sloppy timing chain?
Could be a plugged catalytic converter or a plugged fuel filter.
If the truck is equipped with a cabin filter, the filter may be plugged up with debris.
no it will not
Of course you can. Most people leave their refrigerators plugged in for years. It's actually quite rare for someone to unplug their refrigerator.
