525i 1995 Individual doesn't wanna start after engine swap

[Max6000]

The car is 1995 525i Individual from Japan. Had to replace the engine due to blown head gasket and extensive overheat. The new engine came from e36 325.
It seems like everything connected properly, it cranks good but doesn't wanna start. I noticed that there's no spark at all 6 cylinders and no power on fuel pump. Although power goes from battery all the way to computer. I have doubt that a few sensors are connected right under the intake manifold, because some of them have the same type of plugs. Any ideas where to look?
Thanks in advance.

Is there a CEL when the ignition is turned on?

I want more photos of that interior!

Everything lights up normally, cranks but doesn't start.

Wow.
Could I just connect it wrong?
Thanks.

Perhaps you swapped the crank sensor and cam sensor connectors

^ agreed what ever issue your having is crank sens related, it’s either not plugged in correctly or defective

Thanks everyone for advises, was fighting with this car today all day, nothing helped.
Crank sensor works good, everything connected properly now, car doesn't wanna start.
Is there any way to reed codes? I have also E38 and E39, those cars easy to read with BMW scanner V1.4
What car soft use for E34??
Thanks

Have you got spark / fuel pump running when you crank now? Lots of help around but this article contains a pretty good, methodical approach to fault finding:

Did you use your DME “engine computer” or the e36 dme ? You need to run your computer as it’s ews coded, if you have an issue with your original Dme and need to use the e36 comp I believe cutting pin #7 green/yellow? If I remember correctly ? that will disable ews from the dme giving you the ability to run the e36 dme in your e34. Your car should have a silver label 413, this will not disable ews from the car/key chip just the dme

Ok, here's the last update.
Yesterday car finally started. Most likely that happened after my friend and I yelled, that we gonna burn her down if she will not start! So she did)
If seriously, it was few issues. We accidentally connected fuel lines wrong), crank shaft sensor was plugged to the wrong place and broken positive wire from the battery to computer. Deep under the floor i found a fuse or something, which was giving 2.2-2.5V instead of 12+V
Thanks everyone for help!!!
Happy new year!
