84 Toyota pickup that had a carburated motor in it you put a 86 22re EFI motor in changed the wiring not getting any injector pulse where does the ECU get power from and why is there no injector pulse?

did u install all components like resister,igniter,etc from the 86? the ground 4 inj.goes 2 the intake.distributor from 86 also needed .4 more info email me.

My take is that the MAF sensor enables the fuel pump and the igniter send a signal to prove rpm enabling injection pulse which is then controled by TPS and air flow along with rpm to adjust pulse width, giving the engine more or less fuel on demand.
