    ok guys i have a no start thread i did a few days back . problem is no fuel into cylinder. timing is good checked it , i have compression .i have fuel pressure (using ids i get 6.74 mpa cranking) injectors work tested outside they spray. i have spark. i reprogrammed ecu using ids nothing. i have all grounding points that i can find. my question is can any one name the ground locations in total so i can check if i got all of them ?

    so far
    1: hpfp ground (even extended to negative )
    2: one ground on harness on top of trans
    3: two on front of trans ( one fat one and one small one) (also extended to negative terminal)
    4: passenger motor mount
    5: driver fender area that goes to negative terminal aswell

    am i missing any other grounds ?
    my only problem is i am not having fuel spray into cylinders
    i reprogrammed Ecu using ids
    parameter reset for PATS
    new cam and crank sensor
    new maf
    new Fuel rail sensor
