Cyl 1 on Ka 24de does not work. Checked for spark - it’s there. Measured the injector voltage = 12v, replaced the injector. also replaced ecu and the ignition distributor. What’s left?

Spark plugs, distributor and wires switched-same stuff( Compression seems to be ok as well. Wires look new. Could be that I installed bad injector again? Or the alternator does not generate enough power for all 4 inj to work? Or the fuel pump gives not enough press?

Got it done!😃  
, it was the injector again. measured resistance, the injector appeared to not conduct electricity whatsoever, instead of showing 15-20 ohms.
