Unhappy M52 no sparks

The car is a 1998 328i

Our car ran well until a heater hose number 64211394293 burst, we drove it for 2 miles back to my shop, rebuilt the head, and put back together by the book with BMW tools, needless to said many $ went into this project. Upon cranking I have cylinder 2 thru 5 dead, any ideas??
BTW, this is a European version, which means we donít have any cat converter, or O2 sensors

Are the injectors firing for those cylinders?
Are they firing in the correct order? (i.e. you haven't muddled these injectors up?)
Do you get a spark at all on those cylinders?

Do you want me to lift the rail and give it a crank?

I dont get it, the cables wont reach the adjecent cylinder, besides the cables were tag before desassembly
Do you get a spark at all on those cylinders? how do I go about to check this?, just remove the coil-plug assembly in crank the engine?

To check if the injectors are firing, get a long handled screw driver and put the tip of it on the injector body and the handle against your ear, crank the engine and you should be able to hear if the injector is firing or not.

Get a spare spark plug (and old one will do) and remove the plug lead from each plug in turn and fit it to the loose one, rest the spark plug against the engine block and see if you get a spark when your crank the engine.

I have a mechanic stethoscope to listen to the injector, no problem there, how about checking duty cycle with my fluke tester.
For the plugs you want to remove the coil leave the installed plug as is and install a spare plug in the coil and crank to see if there is any spark.
BTW the can started missing from the moment the hose exploded, I did not check the misfiring symptom back then because I thought we had a blown head gasket plus the fact that the valve stem seals were toasted so I went ahead to tear down everything.
Is there a possibility that a shut off mode signal from the computer is causing this symptom.

I just got back from the shop, and guess what, the fuel injectors connectors harness were not plug in correctly. I had it fix en ten minutes.

Thanks for your help!!!

All good. Glad it wasn't anything too complicated (or expensive).
