Cold weather starting problems with battery

When its under 40(F)degrees the car will not start. I warm the glow plugs a few times, and then the battery dies when i crank the engine. Dashboard goes haywire, the clock resets to 1200. I end up jump starting the car. any ideas?

    i also have the same problem with a 1.8t, replaced the ignition switch, still have the problem...if i hit the base of the steering wheel colum it will connect and recieve electrical power...it is not a battery problem, possibly a wiring harness problem? any help would be nice...thanks

    I have the same issue - my dashboard goes nuts, etc. I haven't "checked the battery" yet, but it certainly seems to be electrically-related. From what I can gather, the thickened cold oil makes the engine much more difficult to turn over, and this puts a strain on the battery that it isn't accustomed to. Add to that the cold weather hurting a chemical battery in general, and you've got a car that won't start.

    once the weather gets nicer(40 degrees or higher) my car will die and sometimes won't even restartas well as shifting very hard.

Have you had the battery checked..Cold weather is the worst enemy on a battery. They work fine in summer but cold will get em.

Ford 2008 F-350 remote starts great in warm weather will not start in cold. all lights glow plugs ect working just wont start truck and only if 35 degrees and below.


Since batteries lose almost half their cranking power at freezing, and since diesels require much higher fuel temps to start than gasoline engines, many recommend using a block heater whenever the temperature is under 35-40 degrees if starting becomes a problem.

My truck is very hard to start when it is a cold motor. Once I start it it cranks right back up but I almost run the battery down trying to start it in the morning.


Question
When was the last time you changed or cleaned the spark plugs. I had an older car and just would not fire up when it was real cold outside. We ran down two batteries so at zero degrees Fahrenheit I changed the spark plugs. No problem after that
also is your carburetor set up so the choke is working properly?

1994 dodge b150 van 3.9 liter will just about start when 30 degrees outside. Sometimes it won't. 40 degrees starts every time


What is the weight of the oil? Heavier oil will cause a sluggish start/spin in cold weather. 15W40 is heavy. This can kill a battery in no time. Other problems are related to hot/overheated problems.

Toyota lucida hard to start most times. occasionaly ok. 2.2 diesel. everything seems to work as should


in cold weather diesel gels up and sometimes causes a no start issue..a cetane fuel additive helps with this issue. if temps go below 20 degrees, add a quart per tankful of cetane to the fuel to help start on cold mornings. also diesels require more amperage to crank than gas engines do..thus a stronger battery is needed..

Won't start below 40 degrees, wait to start light does not even come on


Your glow plug controller is out, or there is an interruption in its power source, etc. Diesels are coldblooded by nature, and most need glow plugs to heat them up before starting in cold weather. The controller supplies the power to the glow plugs, but if it goes bad, or its supply of power isn't there, it won't start in cold weather, and that wait to start light which is also controlled by it won't come on.

93 ford f250 7.3 ltr diesal hard to start in cool or cold weather often run battery down have to recharge battery to start. new glow plugs installed 3 years ago. once started good for the day. warm weather...


This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

THE GLOW PLUG TURNS ON WENT ENGINE IS COLD


Yes it does. Let the glow plugs warm up for 7-10 seconds (the light on the panel should go off) and then crank the engine. If the weather is cold, half an hour of running does not warm up the engine completely so you need to use the plugs for the first few startups during a cold day.

1999 F250 SD 7.3L cold starting problem


Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.

1992 F-350 Dsl - very hard to start when cool


are you using cold temperature engine oil!
if not, try changing oil for cold temperature!

hard starting happens due to the cold temperature, air pressure is low during this season so compression inside the engine is low resulting to hard starting!

make sure that all your glow plugs are working.
