No crank/Temp gauge reading hot

So my frind got a 2003 bmw m3 SMG , after parking it for over a night the car wouldnt start , the fuel pump died. He sent the car to a shop and the car came with a fuel pump done and its being wired directly from fuse box (original wires cut( power wires). The shop changed DME, EWS ignition cylinder because after a fuel pump change the car wouldnt crank and temp gauge goes all the way to red like the ecu is in boot mode or something. Both new and old DME do this ( even If i replace everything back to original I get same as everything with new )
So I tried to read the codes and INPA and my Autel scanner cant see DME. After figgling for a while I got original ECU to read but not the new one.
Still car dont crank it doesnt even make a click when you turn the key because as soon as you put key in and turn it Temp gauge goes to red.
After further talking to my friend he said everything started with fuel pump. So he had his original pump in the trunk and I put 12 volts to it and nothing the fuel pump is cooked. I tracked the issue to EKP module or the relay in the right of the trunk black relay when I told my friend to turn the key for me that relay doesnt click. Could this relay cause temp on cluster to go to red and prevent it from cranking completely? Im hitting a dead end everything I tried , ive read like 16 threads on people having similar symptoms but every one of those threads winds up in dead end as well. If anybody could point out what else I could try Ill gladly appreciate you're help and the time you spent to read this. Please help

When it instantly jumps to red, it means there's no communication with the DME as you saw. I'd guess during the fuel pump change something was shorted out. I'd start checking the fuses in the DME box.
