Car wont start sr swap

Well i just finished up my s13 sr swap into my s14. So i go to crank it i get nothing at all, found some wires wernt grounded, fixed those still nothing. Take a look at the ecu its not getting power wtf. I took a look under the dash and there was some shitty aftermarket alarm wired into the car i traced all the wires back and took the alarm system out of tge harness. I go to crank it again still nothing. I have no idea what to do at this point i need any kind of advice or tips on diagnosing or troubleshooting this shit cuz im lost.

I was thinking about just jumping the starter but that not really gunna solve anything since my ecu isent getting power, it was just a thought.

Thanks

More than likely a wiring issue. Have you tried a different ecu yet just to make sure?

Yea i hooked up my freinds ecu out of his running car and still nothing, im fairly confident in the wiring but idk with the s14 it has a weird ecu relay. Im not used to that since iv really only swapped s13's.

one thing you can do is get a continuity tester. Its going to be a pain in the ass since the wiring harness is in the car already, but you can use it to see if there are any breaks in the wiring between the plugs in the engine bay and the plug going to the ecu.

Alright well messed with the car some more, i got the ecu the fuel pump and the spark plugs to work. I checked the injectors and i have no power at all going to any them.

Anyone have any ideas why my injectors dont work? Possible bad ecu?
