why did you try to rewire the injectors ?

are you needing to know the order in which they go?
If so,
Injector #1 is yellow & yellow-black
Injector #2 is blue & yellow-black
Injector #3 is red & yellow-black
Injector #4 is brown & yellow-black
Injector/Cylinder #1 is closest to the timing belt, injector/cylinder 4 is closest to the trans.

I bought the swap and they guy gave me a different wire harness. so i had to take an obd1 harness and switch the plugs to obd2

so turns out injector 4 was wired wrong. (i guess thats why you get when you do wiring at 4 in the morning) so i fixed it. and still wont start. i get spark, and the fuel rail gets fuel. but injectors wont fire. my ecu works in my buddys civic so thats not the problem. any ideas on what it could be?

Save yourself the trouble, find a DX engine harness, add VTEC wiring and profit. It'll save you sooo much time and trouble.
Otherwise, check grounds, troubleshoot just like you would any other electrical issue.

I had an EX one that I sold for $75, so I would assume they'd be less than that.
Trust me, its worth it.

yea, it'll be a lot easier to do if you start with a good ahrness
you dont need a DX harness, you can use an EX one as well. DX harnesses may be easier to come by.

what makes this a bad harness? this harness came with the car (shell) while the other one didnt have vtec or anything that came with the swap. so we converted the one that came with the car to fit obd2 plugs.
