1997 328is won't start

Hey guys, looking for some help here..
A few weeks ago, I replaced the clucth on my car and for some strange reason after I was done, the car won't start. ..
Did some research and found some useful info,but still no luck getting the car started. ..
I'm some what new to bmw, but have some knowledge on a variety of different vehicles.... with that being said here are some of the things I changed. ..
Battery
Starter
Crank sensor
Cam sensor
Coils
Ecu with the ews
Spark plugs
Fuel pump and relay and yes,it still doesn't start...lol
Does anyone have any ideas? This weekend I plan on doing a compression test...
I saw a post where someone was saying that
They had no compression, because they had washed out the cylinders and they added a little oil and replaced the plugs and got the car started .... Don't know if that's going to work for me, but right now I don't know what else to do. .. if anyone has any other idea, I'm willing to try it. ...I really like my e36 and don't want to part with it... my girlfriends tells me to get rid of it and find another one, but that's not going to happen. ...lol
I'm like a little kid at heart and you don't tell your kids to get rid of their favorite toy...lol
Thanks

Did you mean an ECU with an EWS delete? Because if you simply replaced the ECU, it has to be coded to the system/car or the car will never start.

Yes, I understand. ... the ecu, keys and ews were all replaced as one unit. All came from a good running car.... I removed it and install it into my car and it didn't work. ..put it back on the car it came from and it started....

Everything I replaced on my car, works. ... the reason I know this, because I installed on a friend's car with no issues at all. that's why I'm lost...

Are you sure you got all the engine-to-chassis grounds connected? You wouldn't believe how finicky these things are about having ALL the grounds hooked up, even when it looks like it would make no difference.

It seems like it want to at first, but after a few minutes, it's seems like the battery is dying out... if that makes any sense.... and yes, the battery and starter are both new...

1. Check for spark. Yes, go to 2. No, check ignition system, especially wiring and grounds - anything you removed to do the clutch.
2. Check for fuel. Are spark plugs wet? No? Check fuel pump/filter. Gas in tank?

It ran before you replaced clutch, so FOCUS on anything you may have disconnected (even by accident) when you did that job.

Pull the intake boot off, open the throttle butterfly and spray some starting fluid into the intake, then see if it fires and tries to run briefly. If it does you've got a no fuel issue.

No Start

I know that you don't want to hear this, but Horn most likely got it right. I went through this same hell for two month and in the very end it was a ground wire in the wiring harness that goes to the ECU. There are two different groups of brown ground wires in the harness that goes to the ECU. I installed a new ground wire from the frame to both sets of brown ground wires and it started up perfect. It cost nothing to do, it is just taking the time to do it.

Example.....not an E36, but identical result: the 85 E30 that I did the engine swap into last year had a random miss. Turned out it was a bad AFM, but in the process of chasing the miss I'd changed injectors. I had removed a bundle of ground wires from the harness to the back of the valve cover. Reassembling, I missed one. The car refused to fire up. I leaned over the fender, looking over the fuel lines and wiring to the injectors. I looked down in dejection....and there that single brown wire was, hanging in front of the firewall. Reconnected it, and it started. I've heard of a single thin ground being left loose, not disconnected but just loose on a screw, and the engine wouldn't start until the screw was cinched down.

Just for record, as I've seen some serious shut in my BMW time. Did you buy the proper obdll crank sensor and alike? I had a customer try to use and obdll crank sensor on a m52 once.. It took me 2 weeks to convince him why he shouldn't work on his own cars anymore.

Yes sir,oem.... all the part I replaced are oem. I learned my lesson with my e39 and i wasn't going thru that again, trust me. ...
I have a new harness and ecu... it seems that the owner before me did some shady **** with the wiring. .. I have a new harness, I'll start there..... and with some luck, I'll square everything out....
Once again, thank you for all the help and support. ..
I keep you guys posted. ...
