This 2012 Isuzu with a 4JJ1 Diesel was long cranking to start and would run rough intermittently.
The customer replaced the crankshaft position sensor and the ECM. Still had the same issue…
what I found was a super easy fix, could have saved thousands…

Hello friend, I have a problem with a 4JJ1 engine, could you help me?
Good fault finding!
Had same problem on my old mazda 1st gen bt50 from new.
Local mazda dealership could not solve it underwarranty so took it upon myself to sort out.
Helps when you technically minded!
