I am getting a constant buzzing sound coming from the injector connectors, once i disconnect the main 12v power to the fjo injector driver, the sound goes away, can you guys check my fjo wiring connections:


fjo wire from ECU -----aem

white --- ignition power (+12v) --- yellow/blk B9
red --- injector 1 from ECU --- brown B11
orange---injector 2 from ECU --- red B3
yellow ---injector 3 from ECU --- blue B4
green --- injecotr 4 from ECU --- yellow B5
pink --- injector supply from ECU* ---yellow/blk B9

* 1) if ECU switch ground side of injectors, connect the pink wire to 12 volts
2) if ECU switch HOT side of injectors, connect the pink wire to ground

fjo to injectors ---- factory wire
white ---- common for all injectors--- yellow/blk B9
white/red --- to injector 1 ---- brown B11
white/orange ----to injector 2----red B3
white/yellow---- to injector 3 ----blue B4
white/green -----to injector 4 ---- yellow B5

fjo main power is connected directly to the battery.

did i get these right?

thanks.

 

I fixed the buzzing sound, I combined all yellow/black wires from each injector clip into one wire and connect it to the white wire on the fjo box that goes to common for all injector, but the car still won't start

 

are the injectors firing?

 

I think so, I pull the #1 plug and was able to smell gas.
