Hard Startig 03 duramax

[Mr. Rollin Coal]

My dad has an 03 3500 dually and when you drive the truck for like a half hour or so basically when its totally warmed up it sometimes doesn't want to start. It will just turn over and over and about 15 minutes later or more it will start up pretty much after it has cooled down. Does anybody have any info on this please help thanks..

could be the injectors have a high return flow when the engine is warm, causing the CP3 to not be able to create high enough pressure to fire the injectors.

that sounds exacxtly like the problem because we hooked up a diagnose machine and it was showing lower fuel pressure now how do i fix this problem

New injectors. May be covered under warranty...7 years / 200,000 mile warranty.

is it a problem with the tips or the whole injector?
Im trying to decide on aftermarket or factory?
Because mine has the same problem and its a lb7

brand new stock injectors are about 300 a piece i looked into putting aftermarket ones in but when they are covered under warranty i went with the warranty. and its not really a warranty its a service bulletin because if you tell a dealership its warranty they will argue with you about it,
