The car does not have a battery or charging issue. In tempertures below 50 degrees the engine will turn over but will not fire. Fuel pressure is good, new fuel filter, etc. In warm weather or after it has been **** off for a few minutes after running it will restart. If it sits for an hour in 50 degrees or below, it will not start. The only thing I can do is to leave the key on for about a minute but sometimes this is not enough. Car runs great when driving and does not act like its starved for fuel. No check engines lights, no codes. NOT a Police Interceptor.

so you are saying it's hard to crank ??? or cranking slow causing a no start issue ??? hows the oil ??? hows all the battery connections, both ends ??? what is the amp draw of the starter ??? these are important things to know
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..
Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.
have a 97 crown vic,
in warm weather it idles fine and run fine
now that its cold I have to hold at high idle to have warm up
for about 10 mins.
if I just start it the engine will die with out me holding on foot on the gas
It is normal for batteries to lose a good deal of their power due to cold temperatures. If you want better starting power, try using a battery charger/maintainer overnight. It should charge at no more than 2 amps. The slow trickle charging overnight will charge and warm up the battery and allow it to develop full power for a cold morning start.
there's a possibility that the battery is run down. If it's the original battery, chances are you need to replace it. I'd have the alternator checked as well, however the most likely problem is a worn out battery. It's not uncommon for batteries that have been maintaining their charge through the warmer months to go bad once a cold weather comes through. As for the stinky exhaust, in your attempts to start the engine with a run down battery, the engine probably loaded up with fuel, thereby causing it to run rough and stink till excess fuel was expelled from the cylinders. Hope this helps.
