So it seems to me, that the problem i am having is that 88-89 si distributor plugs are different than 90-91 si distributor plugs.. can anyone verify that? When putting a obd0 b18 into a 90-91 si the distributor plugs up and all of the wires match up on both sides of the connectors.. BUT on this 89 si the wires on both sides of the distributor connectors DONT match up.. One difference off the bat is that the small plug with two wires on the 89 si harness is black/yellow and blue.. The harness on the distributor is also black/yellow and blue, BUT when plugged together the wires are on both sides of the connectors DONT match up.. Before we switched these wires, the engine had no spark on any 4 cylinders, and once we switched them we had spark on all four.. BUT it still wont start.. The engine acts like the sparkplug wire firing order is wrong but we checked it a few times and i know it is correct.. it seems like this 90-91 integra b18a1 distributor works perfect on a 90-91 si harness but does not on an 88-89 si harness.. Does this mean the big plus with multiple wires is going to be wrong.. If these wires for the big plug dont match up perfect will that mess up the firing order? Any ideas? Any solutions?

Its a 89 si hatch.. And a obd0 b18a1 distributor.. I figure that since the engine came in a 90-91 integra is the reason the wires on the distributor match up perfect with a 90-91 si.. But since its a 89 si, the wires from the distributor dont match up..

 

Your logic is incorrect.

Oh well, did you happen to remove the distributor when you did the swap?

 

Check your ignition timing :-D

 

no i didnt, but the a..hole that got the engine from me tried to advance and retard the distributor if that helps..

 

Put the distrbutor in the "middle of the top ear". That should get it close to starting, if t does not keep advancing it; if it won't start then you are going to have to look into it deeper. Also check your grounds, especially the one by the thermostat housing.

 

people tell me an 88-89 td-02u dizzy will interchange with a 90-91 td-18u dizzy.. well why are the part numbers different? To make the small (two wire) plug on the td-24u b18a1 dizzy match up to the 88-89 si plug on the harness, we had to de-pin the connector and switch the two wires.. Does anybody remember doing this to there 91 si when they dropped a b in? i dont? on my buddys 91 crx si, the goshdang plugs on his b16 matched up and the mother started right up..

 

check all the wires on both ends of both plugs to see if they are correct?

this means getting a pinout of both harnesses. one for the 89 SI.. .and one for whatever car the motor came from...

 

I need a distributor pin-out for a 89 si and one for a 90 integra!

 

in looking at the diagrams of all three cars.... the wires should be a dead match coming out of the distributor for both the single cam and the B... now... where they are on the plug is a mystery as i dont have that diagram. if you match all the wires on both ends of the plugs exactly... then it should start.

double check that the wire colors match on both ends.... meaning when they come out of the distributor.. and go into a plug... that they come out the other side the same color they went in... if not.. you need to do some switching.

if this checks out... and no other wiring has been messed with... you need to look into your timing.. or other issues..

 

you might have broke somthing. but i know for sure the dizzy should work. do like i do buy new stuff when you do a engine swap old obd0 ls dizzy go out alot so its best to buy a new one. i got a new ls dizzy for $150 online and works. good luck with you car

 

so what youre saying is it should be plug and play? well its not.. we had to switch the rpm wire and the coil wire on the small plugs.. coil wire was going to the rpm wire on the other side and visa versa..
Now as for colors.. on each side of the connector theres 7 wires.. the problem is you cant match them up color for color.. the distributor has a yellow/ green or green/ yellow wire, either way theres no green/yellow or yellow/green on the engine harness.. Another example, theres 2 solid white wires on the engine harness but only 1 solid white wire on the distributor harness..

BTW for some dumb a*s reason the guy decided to depin the connector off his engine harness to try and match them up, when i told him not to.. and they dont match up so now he's like dur duh dur?!

 

why dont you match your harness to the one on the 91SI?

 

the cars are 20 miles apart lol literally

 

did u try da 88-89 si dizzy? wires should nt b changed? wat engine harness r u using? chx ur tranny grd? good luck

 

lol.. no i didnt try the 89 si distributor.. because is a b18! lolz its an 89 si engine harness and the tranny ground wont keep it from running, itll keep the atrter from turning over.. but it the engine turns over fine, it has fuel, it has spark.. but wont fire and go..

 

Does it have compression then?

 

we didnt do a compression check but im damn sure it does cuz it ran fine in my 91 si, just wont run in this frickin dudes 89 si..

 

Always check these
Compression
Timing
Ignition
Fuel.
I always triple check timing.

 

Why wouldn't you do it right the first time? Set it and forget it!!!

 

man to say that it doesnt have compression is a long shot.. unless something her did made it lose compression which i highly doubt.. any way, it has spark, it has fule at the fuel rail.. im pretty sure the injectors are firing because it tries. but it pops and backfires and even shot flames out of the down pipe at one point, which indicates a ignition timing issue.. but now we have to go and pe-pin the distributor connector cuz d1ckh3ad cut the **** off.. once we do ill check the ignition timing..
