Have you tested for spark?

I know it sounds dumb but make sure your battery is strong enough. I went through 2 weeks off stripping s#!+ because of a busted fuse that looked good. Eventually clogged up my idle control valve(dont ask). Even had my ecu in pieces....tested relays, lumes, alles.......battery was showing 12v with the car off.... I also thought I had no spark. Got a good strong battery on her and she fired right up.

Have u tested dme and fuel pump relay?

Hi, had a similar problem on my 325i e36. Check the dme relay and the dme before going for the ecu. First bet, run a diagnostic.

Phewww it's been a two weeks without my Beemer. So I replaced the dme relay and found there was no power going to the fuel pump fuse. So I ran a cable to another 15amps fuse slot and now there's power to the fuse. But...wait for it my battery is now fucked(drained) and I can't test if the car will start now.

Will give you guys feed back aS soon as I've tried it again.
By the way I tested for spark and it does spark.

im not sure if im on the mark here, i got a m52 motor and when i was short on oil the car didnt want to start, kept turning over but no starting.
 
Check fuel - I usually remove the fuel rail to see injectors if they spit or not.

Spark - I plug a spare coil with spare spark plug and crank to see spark (N.B: High voltage, do not touch :RedNo: the coil nor spark plug during testing), check the CPS plug mine was torn (remove the rubber cover at the plug) over the weekend and reconnected it all was well.

This is what I do on my M50, all the best
