I've gotten some long crank time regularly recently. As in more than a second or two. I'm at 299k on original injectors. I'm bone stock other than a Fass 15o. Hot or cold. Batteries are great, and cranking speed is as fast as ever. Where do I start to look. Runs great after she firearm. T
hanks.

 

Fires. Auto correct. Love it.

 

Injector return flow test and rail pessure readings. Good bet it is injector time.

 

Eeek. Truck runs great. Just pulled my 13k fiver to port aransas and back.
