My 2000 Isuzu Npr is a 4cyl diesel, recently its been harder to start in the morning. Its normally starts on the first crank, So I checked it and it smelled like diesel, so it was leaking on both fuel filters so I changed them and also the air filter. Know the truck cranks but doenst start? What could it be.

When fuel lines leaks, air would get trapped in system and this would result in difficult starting. After replacing the filters and rectifying leaks, the system has to be bled to enable starting.
