Sometimes starter clicks, sometimes turns over engine
I have a 1987 Chevrolet Nova. Problem has existed in warm weather, as well as very cold weather. New battery installed about 3 months ago. Sometimes when I turn the key, the starter engages, turns over the engine, and starts the car. Occassionally, however, when I turn the key, the starter does not activate. Instead, I hear a clicking sound by the starter. Usually, if I try it again after a lapse in time, from a minute to about an hour, turning the key activates the starter and starts the engine. I have not check for loose wire connections by the starter, but question if this is the cause, nor do I believe it is starter overheating. Any ideas? Thanks.

Bad pickup, tough to replace if in the distributor. Also, pull out the computer, it may be located behind the glove box or under the seat. Unplug it and open it up. Look at the computer chips for one that looks burnt. If so, the pickup may also be bad.
It's diesel. Diesel engines do not like cold, but that is normal. I am going to assume this engine has a start delay in cold weather to allow for Glow Plugs to warm up the cylinders before actually turning over the engine. I don't know about TDI's specifically, but I think a TDI Mech at your local Volkswagen dealer could confirm my assumption. They may call the parts something different, but the function will be the same. Sounds like normal operation for a diesel engine in cold weather...obviously, this would be why the engine always turns over immediately in warm weather...no need for the Glow Plugs to warm the cylinders. Best of luck resolving this problem.
You may be correct with what you think the problem may be, but another good thing to check is your coolant level. A low coolant level could cause false readings from you coolant temp sensor, which in turn will cause an engine hunting condition that you described.
cold weather kills batteries this time of year...heres why..most batteries are a chemical factory..the acid and water separate as the battery discharges..also the chemical process is lessened when the air temps go below freezing by around 50% or more depending on the age of the battery..in extreme cold areas, external heat sources are required to keep engines warm enough to run..in alaska for example,the batteries are taken out entirely and put inside to keep warm..sometimes a fire pit is used to warm the engine from below (red hot coals no flame)..also in very cold weather, the engine oil will get very thick..in some cases the oil will actually glue the engine semi solid..locking it up..if its a cheaper oil that whathappens..I like 20 miles north of st louis in illinois and when it gets below 30 degrees outside i place a under cabinet 350 watt heater(used for keeping food warm to serve) upside down under my engine overnite..this keeps the block warm and the oil thinned out..and works very well for me..my car will start whe no one elses will in my neighborhood..hope tyhis helps you..
Timing belt being off one tooth will not cause this problem but rather loss of power and hard starting all the time,
in the cold it will not start, the engine will spin but wont fire is this correct?
There are many things that can cause this, a little testing will be needed, the first thing that comes to mind with the ford and cold weather is the coolant temp sensor, it give computer a false reading and can cause hard starting or even no start, a scan tool would be helpful to see what temp it is give computer. The best way to narrow this down to to check for spark when it wont start, a weak coil in cold weather will cause this problem or bad coil wire to cap, but if you can see if it has spark and let me know, another test is to check fuel pressure, to see if it is getting fuel, and the fuelpump relay,
Let me know if it has spark or fuel when is does not start, good day
more then likely the battery is going bad. in cold weather it takes a good (cca) cold cranking amps, battery to turn engine over. but in warm weather the engine is not as cold and therefore needs less cranking amps. thats why you hear clicking when trying to start car in cold. it is the solinoid clicking and not enough power for starter to turn it over.
The first things to check should be the operation of the choke or cold start.It could be not working properly or out of adjustment.When cold and the key is turned on,you should see the linkages work on the intake of the motor.2nd.Check all fuel filters and lines are all good.3rd.Check the sparkplugs are all in good order.It sometimes only takes one to playup when its very cold and you wont get it going..Try these first and I hope it helps
Hello, the reason the choke improves performance in the colder weather is, because an engine needs more fuel in the cold temp. It doesn't burn as easily as it does when the temperature is warm or after engine is warm.Please rate this answer. Thank you
