How to start

What is proper throttle setting when starting diesel engine when cold? for example no throttle, half throttle, full throttle.

or does it not matter, whatever works?

I have 1994 Ford 7.3 non turbo

if you have good glow plugs no throtle would be the propper way to start... I used to drive an old 7.3 idi with bad glow plugs and you had to pump the chit out of the throtle to get it to fire over when cold... I guess what ever that old beast like is what she takes.

As long as there are no problems with the engine, it should start with no throttle. Once it drops below freezing I plug in the block heater overnight and that really helps and the engine cranks over much faster. If I forget to plug it in, I give just a little throttle, maybe 10% and hold it there while cranking.

Also, once it starts up I tap the throttle a little and it goes to a high idle. Once the idle drops down to normal on it's own, then I start working with it plowing and hauling.
