Sr20det cranks but won't start..

Okay guys.. so this is my first time everrrrrr posting anything. So please don't murder me. Here's the background story.
I just finished swapping in an s13 blacktop into my 98 s14, it had an apexi power fc, and denso 550cc injectors. I was able to start it and idle at the time but after one of the wires to the maf came loose while I was rerunning a vacuum line, I saw an arc, went into the car and my power fc controller wouldn't light up. Nor would the fuel pump prime after I experienced this.. so I disconnected the battery, threw in the old stock ecu, got a red light, heard the fuel pump prime but wouldn't start. It'd just spin for forever.. I figured I'd change out the injectors for something smaller since I figured I was flooding it. I have spark and new hks plugs, but after changing to these old q45 injectors I had laying around, same thing happens. I'd try and let the fuel pressure build up, but now I'm kind of at a loss considering the car will start with starting fluid but die immediately.

The fuel pump is priming, fuses are good, brand new main and sub harness, but I just don't know if maybe after frying my apexi ecu, maybe it caused something else to happen?.. idk
I'm really sorry if this is a shitty question. It's just my first s chassis and I'm not too familiar with it yet.

Oh and on the stock ecu, all I pulled was a 55 code.. and after searching, it doesn't seem like that has shit to do with anything.. lol

Thanks for anyone who reads this! I really want to finally drive this thing before Christmas :c
