Re: JTD 2.4......Non Start.....HELP
first off, do you know if your car has an in-tank fuel pump, or do you have to pump manually after you drained the tank? If manual, check if there's no air in the lines by pumping. The pear or pump button, whatever shape it si should be hard. If this is not the case you got air entering the fuel circuit. Check the connections in the low pressure side of the fuel circuit in that case, especially at the filter.
If ok, it's likely a sensor problem. There are only 2 sensors which would cause a diesel engine to not start. one is the RPM/TDC sensor, the other is the common rail fuel pressure sensor. check the connections though i doubt anyone had to touch these, or anything in the vicinity to do a maintenance.
Get a diagnostic device hooked up, and see if you get 300 bar fuel pressure while cranking... if not go to the next step
the last test you could do is an injector leak test, but ONLY if your injectors are electrohydraulic. this CANNOT be done with Piezo-injectors for it will lead to the destruction of your engine. unhook the return lines on the injectors and plug the lead going away from the injectors. put a hose on the injectors and a bottle to each hose, and start cranking. if there are injectors leaking more than others, these will be the cause for the low fuel pressure, replace them (dealer job, i'm affraid, there's some programming to do)
