I just got my mini me started tonight... it has been in the garage for a month

It is an 88 crx automatic with the dpfi system

I installed a 94 d16z6 head
I bought a new td02u dizzy
I used stock harneddes wehre i could like the dizzy plug and the fuel injector harness... I followed the directions as to what wires to cut and add and so forth... I am 99 percent sure all is correct...
new plugs and oil

I amusing an 88 ecu and have tried another known good 88 ecu ( pm6 )

It cranked for a minute and then roared to life... let it warm up for awhile and was adding coolant to top it off I am going to be using an msd switch to control vtec.. but for now it is not hooked up... i modded the dizzy to fit the block and made spacers for it.. seting it right about in the middle for future adjustment..

THE PROBLEM IS.....

when you rev the car up past lets say 3500 to 4500 ( no tach currently in to see... it just bounces the revs up and down exactly like the stock rev limiter would do at say 7000 spins..

also the computer ( and i tried this with both of them... same result)
while running and with key on engine off will blink out 4 flashes and then 20 flashes... im not sure how to take that... my guess is code 4 and code 20... the 4 flashes seem to be longer than the 20 though.. but code 420 does not seem to make sense ( no jokes here please)

on the computer wiring i have the following wires left over from the conversion

a3 yellow with red stripe

a7 red with black stripe ( I may have confuesd the colors on the top 2 in my description)

b11 green with black stripe that was cut and the pin moved to the b12 spot
b2 orange with black stripe was cut and pin was used for b 10 spot...

I am a little confused by the directions that i used as i was under the assumption that i would need to add a few pins.... but i did not have to ..

once agian my car is an auto and the trans kick down cable is not surrently hooked up....
I would apprecitae any help you could provide...

thanks

are you still using the dpfi intake manifold??? if you are then try using a different ecu...if im not mistaken the pm6 ecu is programed for mpfi...i had that problem when i was learning about motors...i decided to put in a spare pm6 ecu in my crx dx, and i had that exact same problem...tell me if that works..

I am Punxsutawney pa....how much do you know about CRX's???? My bf is pretty knowledgable....and he can't figure it out. How ever we did line the timing belt up wrong instead of using the white line we used the red I am hoping that is what is throwing the codes! thanks for the replys! :bh

code4 is crank angle and 20 is eld
a3 is your #2 injector and a7 is your #4 injector
as for b 10 and b12 those are to your crank angle double check make sure you have the correct wires. looking at my manuals pretty sure you dont have the correct wires

Ok I got it figured out lol.....it was the timing..that is what was throwing the code 4. :noo

..but now it doens't seem like the ***** is kicking in. I checked the solenoid....I sent power through the solenoid and there was a clicking sound not real authorative but never the less a clicking sound. I am not sure what is keeping the ***** from engaging. I have the RPM activation seitch to install yet I was just wondering if anyone had any ideas?

If you dont have a switch installed and the ecu is stock then vtec(fyi, correct spelling) wont engage. You probably wont be able to hear vtec engage anyways on the sohc(I cant hear it on mine).
