my 2003 7.3L. is a bear to warm up, and if I don't let it warm up long enough it will die and is a bear to start again. I added Lucas injector cleaner to see if that helps. any suggestions. I read about an IPR o-rings but, I no idea what that is. Yes I need some help.

 

Miles on the truck?

Mods to the truck?

Gauges?

Location?

Outside temps?

 

106,000
no mods
standard gauges
So.Cal
at any temp

 

Once its running its fine?

Sounds like an injector issue, but without having some basic diognostic on it its hard to guess.

Should not need glow plugs down SoCal right now.

Oil level ok?

 

Injectors is what I thought, in another forum I read about an IPR. what is an IPR. oil level is good

 

IPR is the Injector Pressure Regulator...

 

man that is so cool, so can this also cause my issue

 

Its possible... IPR's act up, but normally its all the time, not just when cold.

 

Great thanks I will have to go get it diagnosed. Thanks for the help. Great starting point
