    I have a F-150, 2001 model, 4.6 engine and it won't start in cold weather now. The battery is new so it's not the battery. If I leave it alone and the weather warms up, it starts without any problem at all. If the temperature goes 40 and below, it won't start again. Sometimes it will start and I have to keep the pedal down to keep it running. The minute I let go the pedal, it quits running. If I keep my foot on the gas pedal for about five minutes or so, then it keeps on running.

    Anybody has any idea what could be the problem?

    I have the same problem, it's not the battery, cause it cranks over and over, it just won't start in the cold. As soon as it warms up, it will start right up. I'm about ready to burn it, I hate sitting in it on cold mornings freezing my a** off trying to get it to start.

I have a 1994 chevy surburban with a 6.5 turbo diesel and it hasnt been plug in for a few month so i was wondering what would b the easiest way to start it and what can i do to make it easier to start for...

By plugging it in I assume you mean the block heater for the engine.
I would plug it in for an hour or two before starting. also give the glow plugs plenty of time to heat up before starting. If you don,t have a garage to put it in try to find a place out of the wind and with direct sun in the day this may help some. laying an old blanket or quilt or even a tarp over the hood and front end could help some. after sitting for a prolonged period of time in cold weather hook a charger up to the battery before starting to top off the battery's charge. Hope this helps.

Won't start in cold weather

Are you saying the starter doesn't spin the engine over? The click it comes from the engine? If so then you have a defective starter solenoid, the design of the starter used in this truck is Japanese, the problem comes from the heavy electrical contact in the starter solenoid get burned away, when it is cold the large metal contacts shrink and make no connection, heat it up and the contacts expand just enough to make the connection and supply battery power to the starter motor itself. Replace the starter and the problem will go away if the answer was yes to my 1st two questions. If you want to replace just the solenoid parts then you can get them most likely from HERE

Stalling when the car start in cold weather

It could be the idle air control valve, this sit right on top of the intake manifold (plenum). It's held in place with 2 bolts and 1 plug with 2 wires going to it. When you first start engine does it rev up a bit then settle down? If so the idle air valve is probably OK. It could also be intake manifold gaskets if they have never been changed and the vehicle has over 100,000 miles on it. That's probably what's going on, in cold weather the gaskets shink up and don't seal causing the engine to stall. It's not too bad of a job to change those gaskets on that vehicle, my son had a 1998 Explorer and it seems to me, it only took me a couple hours.

Maxima does not start easily after sitting in hot sun for a while

Hot and cold? Hmmmmmmmm, interesting,You may want to to have the air temperature sensor replaced. Its a small sensor on the intake duct coming of the air cleaner. You can change it yourself if needed. Good Luck

2004 Sebring.... cold weather...can't get it to turn over and start! Has been in for an oil change a week ago...

My girlfriend just had the same problem. You have to replace the battery. Its located in front the left front tire behind the front bumper. It took about 3 hours to do and is quite labor intensive. You remove the left front tire then remove the screws and rivets attached to the splash guard. Then remove the battery holder and from there switch out the battery...good luck!

Will turn over but not start in cold weather

could just be the oil if you are in a really cold environment (near or below 0), make sure to use 5w-30 versus 10w-30 which is suited for warmer climates..
