2012 S550 Short to positive on 6 sensors
 

I have a 2012 Mercedes S550 it sat for a couple weeks. Went to start it and the battery was dead. Jumped it with my jump pack car started but took forever to crank up. Barely runs low rpm. Give it throttle but it does nothing. Checked it with my xtool scanner. Says Fuel rail sensor, barometric preasure sensor,manifold absolute preasure sensor,Turbo boost sensor,Fuel temp sensor, all have short circuit to positive. Sent the ecu in for repair came back installed it and no change. Installed a new fuel preasure sensor same code for the new sensor. Checked ohms for all the wires that goes into the ecu and none of them had continuity between any of them. I am at a loss as to what it could be. Any help would be greatly appreciated. I got this car for my mom but this has been a nightmare. Thank you

Not in front of my diagrams now so I can't look it up but some ignition Coil circuit designs have them grounded by the PCM when to spark. But some have a ground that goes to cylinder head and has a seperate wire for the coil trigger. Now if that ground gets bad it will make all coils not fire right, until the ground finally gives up and then it won't
