6.5 turbo diesel hard starting
My SIL's '93 GMC has a new 6.5 turbo diesel in it. The engine runs perfect once it starts but if it's left sitting over night it often requires a lot of cranking and blowing white smoke before it star...

4x4 you can do what Cummins said or if you don't have a test light you can just take a wire and go from the + on the battery and just scratch the unplugged plug end. If it's good it will spark. If not, it's dead.
If your getting white smoke it's not going to be a fuel deal.
BTW when I changed my GP controller to a Napa brand it won't heat the plugs long enough. :M IOW's the Napa controller is junk. To get around this and not spend another 100 bucks I double glow it in the mornings.
White smoke is raw fuel and is often caused by a leaking injector. Rebuilt injectors are always iffy.
Not to be confused with black smoke which is partially burned.
I would also suspect injectors with white smoke. But with bad injectors, I don't the engine being warm should have any effect on cranking time.
Injectors were all replaced.... made no difference.
