car wont start. it cranks but its not getting fuel. plugs are dry and if i pour a little gas into the intake it starts then dies. its a s5 turbo. i checked my fuel pressure and when its jumpered it is running at 39.5 psi which is normal but as soon as I turn the pump off it immediately drops to zero and will not hold any pressure. I also dont think my injectors are firing i pulled the CAS off and spun it and i heard what sounded like the main relay opening and a splash but i think it was the fuel pump squirting fuel into the fuel rails since its losing so much pressure. the injectors do have 12v but could it be a grounding problem? i checked all my fuel lines and no none of them are leaking. thanks everyone
