On 1/19, we had snow on the ground, the car was hard to start, like it had a weak battery, figured it was the cold.Same thing on 1/20. Then after it warmed up, no issues.
Starting 1/31 the Tribeca got worse.Now, without warning or reason, the car will not start in the morning.Only in the morning, not in the afternoon or evening.Once we get it started, it will start the rest of the day with no issues, first time every time.
Each time we have tried to start it; my wife gives it 10-15 seconds to catch.
It makes three noises, one sounds like the starter is spinning but not engaging.Then we can make our 2nd attempt and it sounds like the motor is being spun over with the starter, but no fuel.
Our 3rd attempt my wife will feather the gas pedal (like you would do with old carbureted cars) and the Tribeca, after a couple pops that sound like detonation in the exhaust manifolds, will eventually start.Once started it will run rough for 5-10 seconds and then even out and run fine the rest of the day.
This only happens in the morning, but not every morning.She has left it at the dealership for three different mornings now and they cannot duplicate it.This happens whether we use the key or the remote start.
I have the same problem with my 08 subaru legacy 3.0r. Its only in the mornings that it wont start. I have had brought it back to the place where i go in installed twice, first time to up the voltage on the battery receiver and then second to find tach and hard wire it in to the tach wire. still nothing. very frustrating

This could be alot of things. You could have a weak battery and the cells are freezing up when cold. You could have a coil problem. Do you have spark and fuel? You may have a plugged fuel filter, water in your gas, bad module, poor grounds. It could be a lot of things. A loose cable will cause this also. Do you have a service engine soon light when it runs in warm weather?
The problem with car starting is not only related with the plug, it also have to do with the battery sometimes, when the battery does not hold a charge, then the car will take long to start. While trying over time the battery is trying to pick a little charge to be able to come on.
If your engine has a carburetor, the hard starting
problem is most likely choke related. If the engine cranks normally
and the spark plugs are not worn or dirty, the choke probably
needs to be repaired or adjusted.
The choke may be set too rich or too lean. Either way can
cause hard starting. Inside the choke housing is a bimetal spring
that regulates the tension on the choke according to temperature.
If this spring is broken, the choke will not operate. If the
choke linkage is rusty or jammed with varnish deposits or dirt,
it may stick or not operate smoothly. Cleaning with carburetor
spray or solvent may help alleviate a sticking problem.
On older fuel injected engines, a separate "cold start"
injector is used to spray additional fuel into the intake manifold
when a cold engine is first started. If this injector is not
working, the engine can be hard to start. The injector is controlled
by a timer and relay, so if either of these components is defective
it can prevent the cold start injector from doing its job, too.
If your engine cranks slowly, your cold starting problem is
not fuel related, but may be due to a weak battery, loose or corroded
battery cables, or a weak starter.
Check for obvious problems first. Remove, clean and inspect
the battery cables (both ends). Then check battery charge and
condition. (More information on the condition of your battery and battery recharging is available.) If the battery
charge is low, recharging the battery may temporarily solve your
problem. But there's a reason why your battery is low. You probably
have a charging system problem that requires further diagnosis.
(More information on alternator is also available.) If your battery is more than four or five
years old, it is probably near the end of its service life and
needs to be replaced. A "load test" will tell you if
it still has sufficient cranking capacity to provide reliable
Slow cranking during cold weather (below freezing) can also
be caused by oil that is too thick. A high viscosity oil such
as straight 30 or 40 weight oil in the crankcase can make an engine
very difficult to crank when the temperature drops. Switching
to a lighter multiviscosity oil such as 10W-30 or 10W-40 should
solve this problem.
check battery i had hard time starting when cold and took battery in and when i bought it used they had a smaller battery in the car and was not turning the car over. it happened when the battery was weak when it got cold
cold does strange things.. check battery health with load test... check cables especially grounds... test for parasitic leak of electrical by inserting a test light between battery ground post and cable .. only faint light for radio and comuter should exist ..a bright light means a draw and should be discovered by removing fuses one at a time til located ...good luck
Car Batteries last 3-6 years possisble longer/Shorter - Depends on alot of things, 2005 Vehicle the battery is 4 years old. I would clean the battery termals and have a local shop load test the battery for you. If the battery is weak it is best to change the battery now than have you charging system working hard to charge a weak battery adding more cost to a repair later or a no start on a cold morning.
