Have you checked base fuel pressure with a gauge ? Does it have a pump in the tank and also on the frame ?

Have you figured out if you are lacking fuel or spark when it fails to start back up ? Lack of fuel could be a pump relay, lack of spark could be the ignition module or the EEC relay.

White smoke is actually steam, get the cooling system pressure tested. There is an outside chance that the steam is gasoline vapor so get this checked right away

You'll need to figure out if it is lacking fuel or spark to proceed with testing. I carry a can of starting fluid and a spark plug tester to use when the engine fails to start.

In a word, YES.

Did you jump the car to rule out a drain battery? Otherwise check the main fuse and electrical side of the ignition switch

If you look at the label on the fan shroud both the A/C equipped and non AC equipped applications are printed on the same label. Just look closely and I believe one is shown with a dotted line. The change of path occurs around the belt tensioner. Not entirely sure that a shorter belt was needed, the routing of the belt on the passengers side of the motor takes up some of the slack.

starter worn out.. battery with shorted cells..check these.. test the battery for load bearing capability.. it may need replaced..

so you want more heat in extreme cold? block part of the radiator off with a cardbpoard sheet..not more than half of it.. old truckers trick.. some school busses use a snap-on grille cover..it stops the very cold air from cooling the radiator too much and not warming the motor enough to be of any good..

heater core air pocket, or the valve are the first places to look.see if valve is opening & you have a good 50/50 mix of coolant

have a coolant pressure test done on the system and find the leaks. If it is an old radiator with plastic tanks then the tanks may be split (common) -check radiator hoses for splits and radiator cores for leaks. If the hose is enlarged past the clamp replace it as it is about to burst anyway check water pump and check all points where hoses are clamped onto aluminium housings as they corrode under the hoses.

They probably need cleaned as grease gets hard over time. Disassemble the locks, clean them, put back with new grease. I suggest replacing the crappy ford locks with locks made by warn, they are bulletproof. check out this video, its great! http://www.youtube.com/watch?v=JrHONN8mIEY

clean your battery contacts .and check the power in your battery . and check the earth from your battery .

Cat. converter in your exhaust may be clogged, building up backpressure as the engine runs. Pressure slowly releases over time, allowing your engine to start after sitting. A clogged catalytic converter has been known to get so hot it will glow red, espically in the dark.
