My diesel put me down on the road today. 2008 chevy 2500 HD. Ran perfect all day. Got back in to crank and would not hit a lick. Did get it to cranj once and it idled just a minute. Nothing more. My son picked us up and brought us home. Checked my oil and water, belts, to be sure they wernt triggering an automatic shutdown. Got any simple things this non mechanic can try before I call in the calvry.
