problems with icu/ecu??

Hardcore integra fan right here…I’ve only owned one integra, I drove it for three days and thats all it took, I was in love. On the thrid day I owned it I abused her and and she was taken away…I crashed her due to my stupid chioce to speed arround and test my limits with what inexperience I had driving a 5 speed. I’ll never forgive myself for that stupid chioce I made to speed arround that corner.

I was so desperate for another shot.
I searched high and low and finnaly found one…well… just a shell…
a 1992 Rs sitting in someones front lawn.
got it for practically nothing.(traded my bmx bike)
but when I popped hood, to my suprise, I found a B18a1 hanging on one mount!!(driverside) what a mess it was.
i got her home and cranked her over by hand…the engine seems good.
Its been almost a year now and I still cant seem to get it running…
found a 5 speed ysk-1 trans. for 150$
ebay clutch and lightened flywheel.
engine must have been pulled from an older vehicle because the injectors used a resistor box.
so I installed new injectors from venom
I had to change the distributor aswell…
the other day i bought a battery for it to see what i had as far a fuel and spark. my starter isnt connected so no spark(cant track down the right bolts)
checked for fuel at the plugs…nothing
fuel pump isn’t kicking on…
when i first got inside the car i was listening for the fuel pump
turned the key…nothing… only my belt warning and a burn from the automatic seatbelts(forgot about them)when it almost strangled me
and dust in my face from the every vent when the blower motor kicked on
so the ecu WAS good(the belt warning confirmed it)…
but i wanted to make sure it was the fuel pump…
so i pulled apart the dash looking for the m.f.r …
found it thanks to g2ic…
attempted to check it according to my haynes manual…
after getting frustrated trying to figure out HOW to test for continuity…
drank a few beers and reconnected my battery after realizing i hooked it up ass backwards. i quickly disconnected/connected the battery the right way…i didnt try cycling the key while the battery was backwards so i dont think it messed anything up(or did it)… i plugged the m.f.r back in…
still nothing…
now its quiet… too quiet.
Thats when i noticed my seat belts stopped working… (both sides)
no belt warning…
no c.e.l for the couple of seconds while the key is in II … wtf ? ?
all the other lights in the dash cluster still work…
everything but the c.e.l …
now it gets even wierder…
my oil pressure light that should come on while the key is in the II position dosn’t turn on…but when i shut the door it turns on…i opened the door…it shuts off…i close the door and it turns back on… what the heck???
now im tugging my hair out saying omg omg wtf did i do!!!
i killed my baby!!!
freaking out pulled every fuse(one at a time)checking every one of them. not one of them was blown. could it be the wiring?
did i fry my ecu?
checked the underhood fuse box …nothing was blown!!
could it be the battery?
i accidently left it on all night the day before
while i was checking my resorces to diagnose the fuel pump issue.
headlights still kick on strong both high and low beams. i olny have one ground connected from the valve cover to the frame and thats it.
there is no sterio in the car just loose wiring that i noticed sparking off of the cig ligher. could that have fried the ecu when i hooked up the battery before putting the relay in??
I noticed that the ecu has the same connections as the m.f.r
leading my to believe that the m.f.r and the ecu are directly connected.
and when i pulled the ecu apart to check for burns or any indication of a fried ecu i noticed that it has 4 relays. probably to protect it. there was nothing to indicate it burning out.

Just when I think its gonna work , something else goes wrong.
I’m begenning to see why the previous owner gave up.
I’m ready to give up, sell it and, buy a new one.
idk. mabe someone out there can help me??

i can post pics if needed
