Sometimes the cylinoid will make a loud whine or humming when engaged if bad but the best way to tell is to remove it and have it tested.
Bad starter, bad starter solenoid, or the problem might not be the starter at all.
If it doesnt turn over it can be
Not quite sure what you are asking, but if you are changing the solenoid, then disconnect the battery first.
the solenoid is broken. sometimes if you strike the starter motor sharply this cures the problem.
I would check the starter solenoid before I investigated the starter - it's likely the cause. Have someone try starting the car hot while you measure the voltage between the starter side of the solenoid and negative - you should get battery voltage. If not, the problem is the solenoid (or somewhere before it, electrically).
There is an electrical problem between the starter switch and the starter solenoid. The most likely cause is a loose connection at the solenoid or the fusable link has melted.
There is about a thousand reasons a car can have problems starting. Best thing you can do is take it to a good shop or buy a book on your car and fix it yourself.
I had a popular AX4N front wheel drive Ford automatic transmission. When the(lock up) solenoid went bad the car would start and idle but stall as soon as it was put in gear. So, it would run but not in gear. There is a code for the problem. After the solenoid was replaced the trans. would still intermittently have a solenoid problem. After a few days of driving it started to work properly all of the time. I have put over 50,000 miles since with no problem. The trans. had about 100k when problem started. I suggest proper service with fresh fluid.to keep things from sticking inside trans.
is it an automatic transmission? if not does it have a engine start button? in both cases mentioned the vehicle will have a solenoid in the gear shift lever or gearbox that prevents the vehicle being started in gear!
I am having this same problem. I will give a definitive answer once I've had my car looked at but I'm confident that the problem lies within either the starter or the solenoid. Strangely enough, if I bang the starter and solenoid with a hammer a few times the car will start right up. I think the gear inside the starter is jamming and the hammer helps to free it up.
I don't know much about engine codes, but my 1997 Toyota Corolla has had trouble starting. I have been told that the sounds it makes suggest the solenoid is at fault.
The word, 'Solenoid' defines a shape, which turns out to be cylinder-shaped. Solenoid is an adjective . . . that means that it modifies a noun. The noun in this case is coil: As in 'solenoid coil' which is cylinder-shaped. In a car, the solenoid coil, or just 'Solenoid' pulls in the electric contactor on a car's starter to turn the starter. After the car starts, the solenoid releases the contactor to where it will be ready for the next engine startup.
