Got problems with my '90 CRX HF with a B18b swap. The swap is completely done. It cranks, has fuel pressure, but no spark. I pulled out an SOHC that worked fine but of course just need more powa! So I think the harness is fine. I see no messed up wires. Anyways, I have power going into the distributor harness (engine side 2 wire connector), power going into the distributor (distributor side 2 wire connector), power and good ground on top of the ignition coil (with the cap off). I thought it might of been problems with the 2 distributors I had, so and friend of mine with the same car and swap come over and I pulled off his distributor and ECU and put it on mine. Same thing happened......NOTHING!!! Anyone had this happen before? Someone said on the big distributor plug that I have to change the two white wires in the middle row of wires. Any other feedback would help as well. Thanks in advance.

 

did you use the integra motor mounts and axles for this swap?

 

I used the Integra axles but I bought a set of mounts. Can anyone help me with this problem?

 

check your main harness ground that bolts to the thermostat housing, if thats not connected it will not start

 

I got both of those hooked up to the housing. Should I try else where on the engine?

 

Do you have all your grounds attached? Especially the one on the thermostat housing. If everything looks good, try switching the two white wires on the distributor plug, they are often mixed up.

Edit: didn't see the previous post about the thermostat ground, so ignore my comments about that. What ecu are you using?

 

I heard about the two wires in the distributor plug, but I have never removed those before. Is it necessary? Tell me more. The grounds are both good on the thermostat. I checked them with a test light and it has good ground. The ECU that I am using is a PR4 OBD-0. I've tried two already, the current one and one from my friend's running car.

 

Does your engine have a crank sensor???
if so you will have to patch it in to your dizzy.

 

It is a B18B engine but the harness is off of a CRX HF. So even if it did have a crank sensor it still wouldn't hook up to the harness.

 

Can you give me more info. about the two white wires in the distributor? Thanks!

 

What distributor are you using? If you are using an OBD0 PR4, you must use an OBD0 distributor. The pulse count from and OBD1 distributor is different and won't start when used with an OBD0 computer.

There are two white wires that are in the distributor connector. They are often mixed up when the distributor gets re-pinned. One of the wires is slightly thicker than the other, but not by much. From the factory, the thicker wire has a red dot on it to help identify it from the other white wire. Over the years though, the dot can fade or wear off. If you can't get it started, try switching the wires around. Also as it was mentioned in the previous post, what distributor is on the motor?

 

It's an Integra distributor b/c it bolts up to the head perfectly. It has both round plugs, and everything plugs in so I would think it's an ODB-0. Anything else? I haven't tried the two white wires swap yet. You spoke about re-pinning the distributor, I never changed any wires on it before. Which ones should of been swapped? I can do it just let me know which ones need to be done.

which injectors or you using obd0 or obd1?
I don't think its the two white wires cause you didn't convert to obd1.

 

OBD-0 injectors. Correct me if I'm wrong, but that has nothing to do with my spark.

 

Working on it some more and tried the two white wire swap with no change. Also, noticed that the tach doesn't move while cranking. With the wires reversed and in their normal position. Any more ideas?

 

Is it possible for you to take some pics of the distributor and post them up here?

 

Yeah I can. Still doesn't explain why it won't start with my friend's distributor though.

 

It has to be some sort of wiring issue before the distributor.

 

Any suggestions besides "start looking for broken wires?" And which wires should I pay attention to?

 

Edit. Nevermind.

 

Ok I worked on it all day and I'm using both the 90 CRX HF Diags. and 91 Integra LS Diags. I found in the Integra that they have a 10v Ign. Output signal. But when looking for it in the CRX, nothing. No output signal. Which one should I be working with? It has a stock HF harness. That's the only thing that's not working. Is this 10v source supplied through the igniter or through the ECU? I have more info. but see if anyone can answer these questions. Thanks in advance!!

 

Update on what's going on. Found out that I had a bad wire coming out of the dist. to the ECU. Fixed that and now I have communication with the ECU. Now the ECU is flashing a code 15. The Igniter is ok b/c I tried the dist. on my friends car and it works fine. Trying to find out what I need to look for or what ideas anyone may have. Thanks!

this is a site that list the reasons for the ecu codes hope that it helps some... code 15 is the ignition output signal... maybe try using the integra ignt.?

 

I'm supposed to have 10v coming out of the white wire from the igniter but I don't have anything. Also on pins b15 and b17 of the ECU. But I have nothing. So what to do? This distributor works in another CRX with a B18a swap but not in mine.
