I HAVE AN 03 F-250, 6 LITER DIESEL. IT DOES NOT START, EVEN WHEN IT IS 80 DEGREES OUTSIDE. PLUG THE BLOCK HEATER IN FOR 10 MIN. AND IT STARTS, BUT RUNS ROUGH WITH BLACK SMOKE UNTIL ENGINE WARMS UP. ANY POSSIBLE SOLUTIONS?

Yessir.
In the old days, because of the ambient temperature's effect on the crankcase oil and the diesel fuel, often two batteries were used to state the diesel in cold weather.
You might see if there is room for an additional battery on the opposite side of the vehicle from the one that is installed now.
The additional battery can be wired parallel with the one already there, which will not increase the voltage, only the starting amps.
I have done this before, several times.
Another choice is an engine heater, which either screws into the block or is installed inside a radiator hose that has been modified for this purpose.
The cord then is plugged in to an outside 110 volt source, and that will heat the motor oil to ease starting.
God bless your efforts.

try a block heater. your engine is cold simple as that. you could try keeping inside a garage where its warmer or plug in a heater. they make a couple types of block heaters or it may already have a heater.

Is the vehicle a diesel? If so the diesel fuel may be waxing up - particularly if the outside temperature is below freezing?

Its usually from the center out in the next most opposite bolt (star) sequence. ie. if its a 14 bolt head 1-7 top, 8-14 both from front it would be like 4-11-3-12-5-10-6-9-2-13-6-8-1-14-7. you just want to avoid tightening a bolt outside a non torqued bolt to prevent head or gasket damage. torque specs are done in degrees, ie 44 ft/lbs, then run it 15 min then tighten another 33 degrees, then run it another 10 minutes and final torque another 25 degrees.

SOUNDS LIKE YOU NEED A NEW GLOW PLUG CONTROLER

Gasoline engines work with a spark plug, where an electrode ignites the fuel mixture. Diesel engines operate on the principle of heat and pressure. Compression ratios are very high in diesel engines and when the air is compressed into a very confined space it heats rapidly, then the fuel is injected and combusts. Most diesel engines have a "wait to start" light when you first turn the ignition to on. If the temp is below normal, I might would allow for a few extra seconds for the glow plugs to heat up. The block heater will help though, b/c it raises the temp on the engine and allows for it to build the heat neccesary for combustion.

time to have the injectors replace and calibrated by an accredited diesel specialist shop
indicates squirting and not atomizing

Theresa,

Plug in your car and listen for a "sizzle" sound. If you hear this then your block heater works.... if not..... Call Canadian Tire!

if it is a powerstroke im sure it does if it is a V10 triton look for a 110v male connection somewhere under/inside the front bumper. if purchased in a hard freeze state it probably comes standard .

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.
