i did a swap, its a 97 civic cx with a 97 spec itr used everything that came with the complete swap from hmotors and my stock harness, wired iacv vtec and swapped out one other intake plu it turns over but wont start.

to see if my ecu was the problem could i try strarting it with my y7 ecu since its obd2a or will wreck something or not work???? any suggestions would be appreciated.

yes you can start it up with that ecu

but it sounds like the crank sensor is not hooked up

check the coil and icm in the dizzy

CKF BYPASS TRICK CLICK HERE

 

i didnt think i had to do that since im not using a US ecu but im getting desperate so i'll try it

 

my motor should still run without the ckf trick shouldn't it

 

i dont think so

 

and jdm ecu's dont look for vtec pressure switch

 

yes it will.

 

is there any wiring i could have done to wreck the ecu, i did accidently cut a fuel injector wire but i saudered it back together?

 

did you see if its getting spark

 

the injector wires are grounds so that wont do nothing

and what other wires did you cut besides the injector wires

 

just the ones to wire the iacv i cut a orange one and left it out and repined a black and blue wire, and i have spark

 

put a drop of gas(just a little like a 1/8 of an oz) in the intake manifold and try to start it up

and are the spark plugs getting wet

i think its ckf sensor

tryed that and it started until it bunt the gas, so does that mean its a sensor. The first thing i thought of was the ckf but im almost positve i dont need to do the ckf, i dont think it apllies to my setup and it will run without it

 

did you change the injector plug?

if so check the yellow/black wire on the injector plugs to see if it have 12v when the key is on

did you try bypass trick yet? it wont hurt nothing to do it

 

checked all my injectors already and they're getting power havent done the ckf yet cause i took my car to a shop but its been 3 weeks and its still sitting there so im trying to figure it out myself

 

another thing is the injectors could be locked up

 

how do i check that, take them out an see if the squirt fuel when i turn it over? and what could i have done to short out my ecu when doing my wiring. did i need to ground any of my wires cause thats what hmotors said i did

 

try the other ecu first then if that dont work then switch injectors from the old motor and see if it starts up then when it starts up swap the ecu back in and have fun
