I have a D6N that I have changed injectors, fuel pump, relief valve, and blown out the fuel lines. Changed the fuel filters. I have 2000 psi cranking but it will not start. Anybody got anything that might help? Please
A serial number would be a good start, is it a heui engine or common rail engine?
Has the dealer looked at it ? Throwing this many parts at it has got to add up $$$$$ wise and I would get a Cat tech there to at least troubleshoot it and give you a direction.
