have a 2000 7.3 with about the same problem....in Georgia....if I plug it in at night or for about 30 min after an overnight...it starts fine...but if not plugged in very hard or won't start....have been told I need to replace the fuel pump...that will be done in the next week...
TEST YOUR GLOW PLUG RELAY. MOST LIKELY ITS BAD. SHOULD BE ONLY LIKE .2-.3 VOLTS DIFFERENCE BETWEEN STUDS. ITS ON THE PASSENGER VALVE COVER IN BEHIND THE POWERSTROKE COVER. BE CAREFUL CAUSE THE AIR INTAKE HEATER IS RIGHT THERE ALSO AND THEY LOOK THE SAME. IF MORE THEN THAT THEN ITS BAD.
take a screwdriver and cross the relay terminals, the relay is located on the passenger side of the motor on top under the powerstroke cover. if you cross it for about 10 seconds and crank it over and it starts, your relay is bad.
I've had the same problem with my 7.3. Changed the GPR and GP's and it still did it. I've been told it's the nature of a 7.3 to not like it in the cold weather. Single digits to 20's for weeks at a time is what I'm dealing with. Since you're in Fla, I'd guess GPR too.
My resolution.... a shot of starting fluid ( always keep a can with you ). Starts every time no matter what the temp. It does need to stay plugged in though when that cold.
SWITCHING TO SYNTHETIC WILL MAKE A HUGE DIFFERENCE IN THE COLD. MINE HATTED STARTING B4 I SWITCHED. I DONT NEED TO PLUG IN AT ALL HERE IN MAINE. DONT USE THE EITHER THOUGH. YOUR ASKING FOR TROUBLE. HOW ARE YOUR BATTERIES? THESE MOTORS TAKE A LOT OF JUICE TO GET FIRED UP IN THE COLD.
