My musso 602tdi 2.9 turbo intercooler: all the dash lights are dead including the speedo and rev counter does not work. suddenly i battling to start the car as no diesel gets to the injectors

i am desperate. have checked all the fuses and they are ok. there is diesel at the disel pump baut i need to bleed the system and disconnect the vacuum pipe that shuts the engine off and then eventuaaly it will start with a few more diesel bleeding and accelerator pumping. i am desperate. have checked all the fuses and they are ok. there is diesel at the disel pump baut i need to bleed the system and disconnect the vacuum pipe that shuts the engine off and then eventuaaly it will start with a few more diesel bleeding and accelerator pumping.
