ok well im trying to start my hatch with a b18a1 out of a 90 teg. well i know its getting fuel, it has good compression, timing is right, but no spark. im wondering if it was my wiring that i did for the mpfi. well here is a diagram of what my wiring to the dizzy looks like. i think that the ones i said are "tan" might actually be a faded orange or white. any suggestions help

 

anybody?

bump, help needed!

 

come on guys!!! really lost

 

well if u did the swap and has a sohc system, then ur going to have to set it up for dohc system. the 2 wires on the dizzy ur going to have to cut and re wire it to the ecu is a blue with yellow stripe, and a blue with green strip on the dizzy on the bigger plug. now for the ecu u have 2 black plugs that go in the ecu? if so the smaller on of the 2. there numbers on it u have to cut number #2 wire and #29(easyer way to explain it is if u have the thos plugs pluged into the ecu it the frist to next to the bigger plug. iam not sure which wire gose were u will have to play around with it lol but make sure u cut the wire so u have room to play with.

 

Agreed! Good luck

 

so for the mpfi on a b18a its different then for a sohc?

 

yea u got to rewire the injectors give me untill the end of the week and ill have i diagram for u. u have the egine harness for acura or of ur hatch ? idk if there a diffrenets. but every thing lines up harness wise. egine to main?

 

Do you have the right ecu?

 

check rywire.com or just put your plug back to stock if you can remember the wire pattern and get a conversion harness off egay

 

i just found out that the actualy guy ryan from rywire lives around me, weird :D

 

I'm having the same problem with my STD to Si MPFI. Good luck man.

 

cool!

 

ok well i tried switching out the coil pack for a one that guaranteed working condition. still no luck, so im convinced its the wiring. can anyone tell me what wires go to where? cuz im lost and need this running!
