ok i have used the hybrid site to get the diagram from...i wired everything and it still is not getting any spark..i have swaped the the 2 white wires around also..tryed another distr. and diff ecu...as far as i can see everythiung is wired right...can cam timing throw this all off..i figure cam timing has nothing to do with the distr. throwing spark....i really dont have the extra money to take this to a shop and get them to redo things...please tell me any thing that might help..i need the car to run to get a job to pay the bills...thank you for any info....EF RULES!!!

 

please help me out asap...any info will help...i need the car running soon...

 

When doing this conversion (and I have done two), match up the wire colors for the distributer wires all the way from the 1992-1995 ECU plugs to the distributer plugs. In other words, make sure there is continuity between, say, the orange wire on the 1992-1995 plugs and the orange wire on the distributer plugs. And make sure the wire is in the proper place on the distributer plug. In other words, make sure it matches up with the actual orange wire on the distributer itself.

 

The colors on the '89 CRX distributor plug and the '92 LS distributor plugs are the same, but they don't match up. If I remember correctly there are 4 pairs of wires and two of the pairs are swapped. The easiest way to wire it is get a 90-91 teg ECU and 90-91 teg distributor. They should both plug in if you've done the MPFI conversion. If you use a 92+ ECU and distributor, you'll have to rewire the ECU harness, injectors, and distributor to the newer plugs. I tried wiring a 92 teg distributor into a 91 teg ECU and it didn't work. The car would run but it would throw the CYL or CRANK code and go into open loop mode. From what I understand, the crank sensor is different in the 92+ distributors. I think Blown90Hatch (spell?) sells the OBD0-OBD1 conversion harnesses which would greatly simplify your wiring.

 

i am using a 91 teg ecu and a 90-91 teg distr...my car was a dx so i had to add 2 wires to the distr.(direct ecu connection)...the dx distr plug only has 5 wires..the two extra wires blu/grn and blu/yel had to be run to the ecu plugs C1 and C2 i have fucked with the car for 2 weeks now swapping wires and distr..i give up and need the car running so i am taking it to a local shop like a loser...it makes me feel like **** to pay someone to do something so damn easy...it really sucks!!!!!!

 

thanks for all the help though.....this is really a great group to get help from.....

 

Did you ever get this fixed? What happned?

 

make sure you run c1 and c12 to the distributor "c1 blue/green"" c2 blue/white"
then conect c1 and c2 harness end to the pins added at b10 and b12, if all is hooked up right there will be continuity between all the ecu pins and the distributor plug's
c1 blue/green cylinder position sensor
c2 blue/white cylinder position sensor
b10 orange, crank angle
b12 white/ with red on it ,crank angle
c3 orange/blue TDC
c4 white/blue TDC
all these should be checked for contiuity if they have it you got a distributor problem good luck, Jason

Both 1988-1991 MPFI cars and 1992-1995 cars have seven wire plugs on the distributer. Six of the colors are the same - orange, orange/blue, while, white/blue, blue/yellow, and blue/green. The seventh wire is fatter than the rest and is white on 1988-1991 cars and yellow/green on 1992-1995 cars. Put the fatter white wire on the 1988-1991 harness in the same spot that was formerly occupied by the fatter yellow/green wire on the 1992-1995 harness. As for the other colors, put them in the same places that were formerly occupied by the SAME COLORS on the 1992-1995 harness. If you have a DX/STD, you will not have the blue/yellow and blue/green wires. Add two wires in their place (preferably the same color if possible) and run them to the ECU plugs. At the ECU plugs, also match up like colors. Make sure there is continuity between each color wire and the corresponding color wire on the distribuetr plug.

 

One more thing. Although the colors are the same on the distributer plug between 1988-1991 cars and 1992-1995 cars (except for the aforementioned fatter ignitor signal wire), the wires do not serve the same sensors between the two (ie, blue/yellow and blue/green are connected to the CYP sensor on 1988-1991 cars but NOT on 1992-1995 cars). But if you match up colors between the 1992-1995 ECU plugs and 1992-1995 distributer plug, all will be well.

 

well i got it rewired by a local shop and the car is still not getting spark..and the fuel injectors are pumping fuel the whole time the key is on..and the check engine light is staying on..but there is no ecu code..i have tried a diffrent ecu but that was before i got it rewired..the haynes book(i know it sux) says that the ecu might read code zero or no flashes i guess and check a fuse...FUSE ONE????what fuse are they talking about???i really need help getting this thing runnig...someone said something about a relay a starting relay or something under the dash???thank you..brandon any help is greatly appreciated thanks again

 

Here's a link to the distributor wiring diagram from a helm manual (from quickhonda.net)...
http://24.95.142.82:6080/manual/2gem...em-90-24-4.jpg

From the diagram...

ECU |
Pin# | Dist. color
9 => Blue/Yel (CYL sensor)
1 => Blue/Grn
10 => Wht/Blue (TDC sensor)
2 => Orn/Blue
16 => White (Crank sensor)
15 => Orange

8 => White (Ignitor signal)

The pin#8 white wire is the loner on a row by itself when you're looking at the back of the plug.

The colors won't match your stock DPFI harness. On the DPFI harness, the 9 and 1 pins (on the ECU side) go to the crank sensor, NOT the CYL sensor like it should for your LS. This is what I think your setup should look like...

Engine Harness | Distributor
White (ECU #9) => Blu/Yel
Orn (ECU #1) => Blu/Grn
Wht/Blu (ECU #10) => Wht/Blu
Org/Blu (ECU #2) => Org/Blu
New wire (ECU #16) => White
New wire (ECU #15) => Orange

Big scary post. I really hope that helps. My setup was almost the same but with an '89 Si, not DX so I didn't have to run new wires or swap pins. Can anyone verify the pin-outs?

 

well swap the distributor, if you have no check engine lights it is probally hooked up right, not the first time a b series, distributor is DOA, Jason
