What to do if my Detroit Diesel 50 Series cranks but will not start?
- A
  Andrew MorrisonJul 28, 2025
  If your Detroit Diesel Engine cranks but doesn't start, several issues could be the cause. First, ensure you have enough fuel by checking and refilling the fuel tank if necessary. Next, check for air in the fuel system and bleed it to remove any air. Inspect all fuel connections and tighten any loose ones, and replace any cracked fuel lines. If these steps don't resolve the issue, the fuel pump may be faulty and require replacement. Also, make sure that there is an adequate supply of fuel. Finally, inspect the DDEC for faults and test and replace any faulty injectors.
