2002 Other Mercedes Benz Models Won't start

This is a European model car with an 8 cylinder CDI system. Car was running fine but along the way a water hose failed and the car overheated. After replacing the hose the car won't start. We have fuel all the way up to the injector lines but it won,t start. Sprayed some carb cleaner into the intake engine will run for a very short moment and die. Those injectors are electronicly controlled. There is no air in the system, replace the crank sensor, the fuel pump but to no avail.

Thank you
