Ok so from looking around these forums, I found out why my freshly swapped 1991 Civic with a D16Y8 in it does not start. I am running a OBD1 P28 ecu and so forth, the dizzy and alternater from the Y8 will not work with the P28 ecu. Is there ANY WAY WHATSOEVER to rewire the Y8 dizzy and alternator to work with the P28 ecu? please help. It took me 4 months to figure out why my car wouldn't start, now I wanna see if I can rewire them instead of just getting a D15B7 dizzy and alternator. I AM BROKE. HELP!


Basically I need a pinout to be able to use my OBD2 D16Y8 dizzy on my p28

 

what year d16y8 motor? the 96-98 is different than the 99-00.

 

cheap solution for the alternator: use your old one

 

Dizzy from the Y8 will work with the P28.
Why wouldn't it?
OBD1 and OBD2 are compatible... it's OBD0 that isn't.

 

the motor is from a 98. sorry i didn't make that clear. is there any way of repinning or rewiring the dizzy to work with the p28?? any diagrams or anything like that?

 

Lifted this from http://crxcommunity.com/viewtopic.php?t=2558

"First off you want to make the dizzy conversion harness. Go to a junkyard and cut off the harness side plug for the dizzy you are using. In my case this was a D16Y7 dizzy from a 98 Civic CX. It would be ideal to cut the dizzy side plug from an OBD0 car, but I couldn't find one. I decided to solder into the main harness because I didn't have another choice, and it's only 9 wires so it's easy to return to stock. Basically you just need to match colours, here are OBD0, OBD1, and OBD2 dizzy wire colours and functions, these are all verified by me after hours of verifying and checking, don't trust every post you read on Honda Tech! This wiring kept me hung up for a week getting no fuel, but I got straightened out by Ryan (the Ry in Rywire).

OBD0 OBD1 OBD2 Function
Orange Orange Yellow CYP P
Small White White Black CYP M
Orange/Blue Orange/Blue Green TDC P
White/Blue White/Blue Red TDC M
Blue/Green Blue/Green Dark Blue CKP P

Large White Yellow/Green Yellow/Green ICM
Black/Yellow Black/Yellow Black/Yellow IGN

now was you getting fuel all the way to the rail but the injectors wasnt pulsing? thats my prob right now. not meaning to thread jack by the way lol

 

haha i just got done doing this on my 95 z6 block with a y8 head with a p28 all the colors of the dizzy are the same just different plug ends i have diagarms

 

Post or send them PLEEEEASE!!! I am SO CLOSE to getting it started.


Please understand my persistance. I have watched my baby sit for 4 months. I am so close to being able to drive her again. HELP HELP HELP

 

also this is wrong. i looked at all the wiring and the dizzy wire colors are not all the same. i cannot match colors. i am going insane. please help. anyone who has wiring pinout or diagrams for both D16Y8 and D15B7 dizzys. PLEASE HELP. i cant seem to get it. I'm getting pretty stressed and depressed over this

 

c'mon, SOMEONE has to know how to help me in some way.

bump bump bump

 

I am guessing that you are running an aftermarket distributor like a distributor king or something of those sorts?

Format: OBD1 (Dist King) Distributor --> Engine Harness

Tan Blue --> Orange Blue
White Blue --> White Blue
Yellow Green --> Thick White
White --> Orange
Tan --> Thin White
Blue --> Blue Green
Blue Yellow --> Blue Yellow

 

i have a 2000 d16y8 converted to obd1 with a p28 . what dizzy do i need to be compatible with the p28? im sorry im a newb. this is my first honda

 

either obd1 or obd2 will work. just make sure you dont get one from a 99-00 since those only use a single rectangular plug with 7 wires total as were we use 9 wires total. so pretty much anything from 92-98 will work.
