The condenser fan is more likely to run when the car is idling. So if it NEVER comes on when idling you definitely have a problem. If the condenser is not cooled, then your compressor could get overloaded. It may be a problem with a relay that is preventing the fan from running - or some other issue.
The radiator cooling fan is most likely not working.
30 seconds of idling equals one average start, on a normally-functioning start.
Sure it still has gas?
Usually, it is your fan belt slipping due to moister. You can get a spray for it at your local auto store.
i had a fuel leak
I sat in my car in the driveway with the car idling, waiting for the kids to come out.
A radiator fan is designed to operate only when the coolant is very hot, and the motor is in danger of overheating. You do not have a problem unless the motor overheats after sitting still idling for prolonged periods of time.
a longer cam shaft will make a car idle rough
either the thermostat or the fan is no good. You would need to locate the thermostat and see if its stuck open or closed!
That's actually the preferred method. You hook up the jumper cables and attempt to start. If the car does not start immediately, you stop cranking and you start the other car, let the other car charge the first car for a bit, and then retry with the other car idling.
The car will start. If it is malfunctioning, then the car will overheat. If the car overheats, it may not start again for awhile as a safety feature, or it may not start because of heat damage. On newer cars if the car is cold, then the electric fan will turn off. It only turns on when the antifreeze needs cooling. On older belt-driven fans, the fan runs all the time.
