What makes a 24 valve cummins hard to start?

A 24-valve Cummins engine may be hard to start due to several factors, including fuel delivery issues, such as clogged fuel filters or a failing fuel pump. Additionally, problems with the fuel injectors or the injection pump can lead to inadequate fuel atomization. Other potential causes include electrical issues, like weak batteries or faulty glow plugs, and low compression due to wear or damage in the engine. Diagnosing the specific issue often requires checking these components systematically.
