MIL's truck had a clogged DPF, so the local shop deleted it and installed a tune.
Fast forward one year, truck has a no crank problem
Local Cummins Service center replaced the TIPM; now truck cranks but will not start.
They then did a thorough diagnostic and are saying no communication with ECM.
So they want to replace ECM and re-flash it to stock.
Will it need a DPF also? Is it a problem to return these trucks to stock after a tune?
