Default Swap Issues - D to B

Okay, ill try and explain this as best as i can.

We just swapped a B16 from a 2000 SiR into my buddys 98 which had a D16y8 in it. The B harness was all hacked and cut up cause we got it from a wrecker, when they removed it they just cut everything prettymuch.

So we used the D16 harness, everything plugged in all the plugs were the same - except the alternator plug, distributor, and the injectors. So we took the Alt, dizzy, and injector plugs off the cut B harness and saudered them onto the D harness.

We go to start it, it struggles to start just turns over, fires a few times. Then the second time i turn it over it starts up slowly, idles real rough and runs real rough, then starts to rev up a bit like any car does on a cold start. I let it run for about 10 seconds, then i shut it off.

I tried starting it again and it kinda fired maybe 2 or 3 times, but didnt actually start. Now nothing. It wont start or even fire period.

We pulled the plug wires and stuck a plug inside them, no spark anymore.... Not sure why....
We havent plugged in the primary o2 sensor yet cause its gotta be lengthened. Pretty sure its thrown some codes already.

Does ANYONE know wtf is going on here..lol. Please help.

nope i dont think so. The D harness is from a 98 civic, d16y8, which 98 is obd2a. The motor that put in is obd2b. But we got a obd2a to obd2b conversion harness.

well either way then u have wrong parts

either get obd2a dizzy for motor, and inj

or get obd2 harness and put plugs back on like said in my op

either way u need to match all parts to same OBD

I guess that makes sense. Thanks alot for the info.

Or could we try and find an uncut obd2b harness for a b16 and replace the entire harness right down into the firewall to the ECU?

How is that mix-matching? OBD2b motor, buy the OBD2b harness thats supposed to be for it, Running the ECU thats supposed to be running this motor, which is also OBD2b. Shouldnt that not work? lol

lol yeah the 96-98 civics are OBD2a, and the 99-00 are OBD2b. So the motor we put in is OBD2b cause its from a 2000. Were running it with a 98 OBD2a harness.

And...agreed. OBD2 is junk, thats why i converted to OBD1 in my prelude. Hondata s300 babbyyy

in the same post you said "96-98 civics are OBD2a" then "Were running it with a 98 OBD2b harness"... its probably just a typo but maybe something that was overlooked
