Injectors going bad?

I am not really familiar with this subject, so please correct me where I am wrong.

Almost every time I turn the key to glow plug my truck, I can hear an injector sqeak, or at least that is my logical conclusion.

What does this mean?

Need more info on said injector squeak..... Our injectors work off of hydraulic pressure. I.E. if the engine is not turning there is no hydraulic pressure built to "fire" the injectors. Now each injector does have a electric solenoid on top that may be subject to fail, but unless you have a tremendous amount of miles onyour injectors it is highly unlikely.

How many miles? When was the last oil change? Is oil level full, correct grade and weight?
