check for burned out glow plugs

What year model do you have? Does it start if you plug in the block heater? There is a computer update from Ford that can be installed to improve cold starting problems.

Most likely your truck has a block heater and you have to turn the ignition on to start the heater up. its that hissing- buzzing sound you hear whe you first turn the ignition on when its cold, that's why the motor emblem on the dashboard is red
glow plugs, glow plug relay, poor compression on engine are some things that will give problems
Make sure you wait long enough for the glow plugs to charge. Check your fuel and power systems. Add a bottle of 70% alcohol to the tank to break up old or cold fuel.
The 2006 Ford F2 50 diesel engine might have a bad fuel injector. The injector can cause the engine to not run properly, until the engine warms up.
Most diesel engines have a block heater that heats the engine coolant so that the whole engine is warm to make it easier to start on cold mornings because a diesel uses compression heat to ignite the diesel fuel.
Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.

pickup speedometer does not register from a cold start. Shifting lurches and then all evens out after about 30 mph
get yourself a GOOD battery with lots of cold cranking amps and keep your terminals CLEAN. Have that same problem with ford f250 supercab turbo diesel - have to use starter fluid to get it started once it sits. someone told me that the glowplugs aren't doing their job, is this true?
most likely it's a bad thermostat, or your vents not working properly.
To find the code numbers for troubleshooting a 1990 F250 with cold start issues, it's best to take the vehicle to a mechanic who has a diagnostic machine. The machine will provide the codes which can then be used to refer to the vehicle instruction manual.
The battery cold cranking amps is 650 to 850 ( optional ) according to the Owner Guide and fordparts.com
