2004 525i no start
I have a 2004 525i got it no start, cranks, has new fuel pump, 50 psi fuel pressure to rail, starts on starting fluid, getting low injector codes for all 6 cylinders. Could it be a faulty dme? Checked all fuses in the trunk and in the engine bay. Replaced fuel relay in the glove compartment. Any advice is appreciated

No physical damages on the board that I see, btw when the key is in the on position, should there be voltage to the injectors or only when cranking?

I was asking more for water damage as these really don't go bad unless the cooling fan dies but definitely a possibility. Yes you're supposed to get voltage on acc

Cooling fan? Also I’m not getting ground or any voltage to the injectors when cranking it, checked for corrosion on the I think 5 plugs going to the dme, no signs of water damage that I know of.
Also I would like to add that when turning the key to the on position one of the errors is, ignition malfunction it still cranks it just tells me to have the brake pedal depressed, lastly on very rare occasions it will sputter couple times when you first try to crank it but die and just crank.

If you have that error then that's why it's not cranking. Need to be looking at your transmission and the connector to the EGS. There's a cooling fan at the bottom of the DME area that keeps it cool. You'll have an error for that I believe. There will be no ground if you're having that error
