h23a1-h22a swap no start

Ok, I am new to forum and to hondas..a good friend had his h23a1 pulled and installed a h22a. the guy that did it cant get it to start.
What I do know is this..they swapped oil pump and put a new crank/tdc sensors in front of motor...they got spark, will start and run if spray in throttle body. noid lite test injectors very intermittent flashing. so it seems to me we got spark and timing is ok..
What sensors does ecm need to see for injectors?? 2001 prelude.. very intermittent injector pulse when using a noid lite...original harness, distributor, external coil, oil pump & a new tdc sensor from advance auto...they used injectors and intake from new motor, and motor did not have a ecu with it, so original ecu as well..viper alarm removed, and added 2 additional grounds from battery to engine & 2 more from engine to body
also checked grounds at ecu, and grounded ecu itself as well.. injectors measured 11.2 ohms from what i have read is high impedance injectors which should be used on the original 01 lude??
the ecu for the car...he did not get an ecu with new motor
The ECU that came with the car is a p5p so if i understand correctly, that ecu should also work with new motor??
