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

What causes a 5.9 liter diesel to turn over multiple times before it cranks when it is cold?

A diesel engine uses the heat of compressing air to ignite the fuel instead of a spark plug like a gas engine. When it is cold it takes a bit to get enough heat to get it to fire. Ford diesels use a glow plug to heat the air when cold starting, but on a Cummins they don't use them. A simple block heater should make it easier to start when it is cold.
