I have a 08 ds 450. First got it, it started no problem for 3 days. Then it just quit starting. Had to be bump started. Replaced battery, solenoid, relays, coils, plugs n wires, and still would turn over Barely like it had a dead battery. Battery was brand new. Took it to the shop. Intake cam was broke in half. Had it replaced, valves adjusted and timing checked. Still won’t start but will bump start. Once it runs for awhile and gets hot it will start electrically but not when it’s cold. Now I have a engine light on when I bump start it. Stays solid for a minute then starts flashing then goes back to solid. Any ideas why I can’t get it to start electrically and what the engine light means?
