Hey guys, i got a 2013 XJ 5.0 SC. i bought it from copart.

primary damage was 'undercarriege' secondary 'mechamical'

when the car arrived, it barely light the dash, had missing hoses, bolts, fuses, air ducts, etc.
as for the damage, it had bumper, hood, front reinforcement bar, cracked oil pan, driver side engine mount and brakcet were broken (engine was tilted). it had no oil, coolant and steering fluid. -> ALL THESE are fixed/ replaced (as far as i noticed). from the looks of it, you can see it had a small hit on the lower front-left side (steering airbag was deployed).
no broken suspension arms or anything underneath the car except oil pan which was cracked.

note : engine spins by hand both ways.

main battery i bought brand new yesterday, the smaller one today at Walmart, and it's EverStart ESTX14 AGM, about 95$, as i was reading on this forum that people tried it and works.

with engine fully assembled and fixed i go press the start button, and dash lights with bunch of errors (pictures above), then i press brake to start engine, and i nothing, the dash turns off and starter NOT even clicking.

i put scanner (cheap one is only i have) and i get only one code U0100 lost communication with ECM/ PCM.

i checked all the fuses, realys, grounds, connectors, wires and everything seems good (im still gonna continue check, because im 999% its a connection but i really don't know where it could be)

if anybody experienced something similar, or knows something, please tell me, it's huge help in fixing this car.

 

Look for the inertial cutoff switch that will have been switched at the time of impact. I'm not sure where it is on the X351 cars, but on my previous car, an X350, it is found on the LH side of the car behind a panel in front of the front door.

Considering the state of the car, I wouldn't be surprised if a few electronic modules are missing, like the ECM. Have you checked?

 

so i followed that link, anf it takes to to the airbag control module, it's directly unde the rear seats climate control.

how can i check it? i need to buy another one or needs reset from dealer?

 

You might have ruined the engine by turning it both ways!!!
Read up on this as it will happen.

the engine didn't have any fluids inside so it didn't force anything

 

A dealer can reset it, but so can you merely by pressing a button on the switch once you've found it. AFAIK its nothing to do with the airbag module, and is found inside the panel in front of the driver door, but I may be wrong. The inertia switch cuts off power to the engine, fuel pump, controls when its tripped by sudden deceleration, like in an accident. Of course your car model may not have one, its the model after the one I had.

 

Fluids or not Jaguar very specifically says do NOT rotate the engine backwards.
Suppose to mess up the timing chains and tensioners some how.

first is the airbag control under rear climate control, the others are passenger foot area
