I need the help from the great @gbalthrop

Help

I need your help so badly on a no crank no start issue with my N54 motor.
Recently my car had a slight fire and was down for a bit. In the meantime I have replaced any parts that were damaged or needed to be replaced. The DME was fine and had no damage.

After putting the car back together I got a no crank no start issue I've been dealing with. Also the fuel pump will prime when I open the doors but when I put the car into igniton on mode right before you crank it up, the fuel pump constantly is running and wont stop. When I try to crank I got just one click, but now I have the car attempting to start. And also I checked spark plugs because I smelled gas and my 3rd cylinder has had gas sitting in the cylinder twice, but this was before I replaced the injector. I have the typical codes with it also.
I have A0B4, U0100, A0B3, CED4.

If you can help me out please let me know! I do have INPA, ISTA and all the other programs but don't have a K/DCAN cable to hook up to my car. Just got my scantool for now, and I forgot to add the car does have JB4 on it but I have tried with it removed and not with the same problems either way. Also I have checked and refreshed any connections that look damaged on DME, CAS, JBE but there are no damages or water in any modules.
