Hello so i purchased this 1999 honda civic ex that someone started a b series swap. The block says b18b1,under the valve cover says. 00 04 7. And the computer is from a 92 93 integra what setup do i have what do i need it will not run i dont have spark it did now it doesn't. Injectors fire .im prepared to tear apart and start over. Never done this swap what do i need!!!!! Please!!!!!

Check whether voltage reaches the coil and ICM inside the distributor. If not, check dash fuse 9.

Did it ever run with this setup?

Turn key on but don't crank, check that the fuel pump primes and the check engine light comes on then goes out. Put test jumper in and see if there are any codes.

Cranking or running the engine with a spark wire disconnected is likely to blow the coil. For compression tests (which you really need to do on this unknown engine) etc. always unplug the low-voltage wires to the distributor.

ecu needs to be from a 94-98 integra with the correct jumper harness. obd2b to obd1 for 94-95 96-98 is obd2a 99-00 will plug directly. you can buy those off of ebay start with the correct ecu first then move from there. check for spark and fuel

Im trying to figure out what i need like correct ecu wiring harness ect..my block says b18b1 the date under the vall cover saya 00 /04 /07 going in a 99 civic i have bo idea if it has ever ran i on this setup. The only way I have ever made this car run is by taking my Power Probe connected to the positive side of the battery and on the ground side of the injector pigtail trying to check for pulse it just started the car car ran like s*** very lost

I dont think just spark is the issue right now my motor says its from 2000 my computer is 92 93
from what i read i have a obd11 motor

muellersfan

Regardless, no voltage to the distributor would cause no spark. You're overwhelmed and have zero focus in this thread. Troubleshoot one obvious symptom that could explain the no-start. It could be the breakthrough you desperately need.

Rogers3232

Yes i totally understand that i will do so im wondering if i did blow the coil like whay was said when i did a compression test and didnt unhook the distributor. But whats weird is when i try checking for injector pulse i put my logjt test end on the postive post of the battery and then prob the ground wire on the injector 3 it will start the car run just rough and really rich. Anyone else seen that before?

muellersfan

It's possible, but test the voltage first. If voltage is found, you can then Ohm test the coil.

This^ does not fit with no spark. Redo the spark test. You need to provide accurate information to get help from others.

Rogers3232

Yes ik very lost im using my mac tools spark tester ik it works goimg to check voltage in a.m but i am ordering the correct computer for the motor from what i have ready 1992 93 are obd1 like most cars and i have a 2000 b18b1 obd11

Rogers3232

This is accurate info. i bought someones attempt at a swap and am trying to find info at this piont im not worried about spark. Im trying to confirm with others who have more knowledge of these motors as i am a chevy guy. All i want to know is what is all needed for this swap. B18b1 under valve cover says 00 04 07. What computer i need what needs to happen to the wiring harnesses ect..

OP, you are really attacking this the wrong way. It makes ABSOLUTELY NO DIFFERENCE what year engine you have and what '92-99 LS ECU. Notice I didn't include the '00-01 LS ECU... they will require an immobilizer system at the key to allow the engine to crank... and your civic doesn't have this, so please forget the idea of getting an ECU that is the same year as the engine. The difficulty here is this car didn't begin as a STOCK unmolested car, so we cannot assume anything that you have as gospel... making suggestions to you as to "what you need" is literally impossible at this point.

Please answer the following:

1) What state do you live in ???
2) What are the annual inspection/emissions tests required to register the car ???
3) What is your capacity to take photographs and post them on this thread to show those of us here that want to help you identify your current components and formulate solutions for you.

Rogers3232

Okay that is somethimg i wanted to know is that the computer i have is compatible. No need to get upset im not going about this the wrong way im just trying to figure out what i have before i do anything else. I was simply just stating the things i have found so far.Yes i can get pictures today. And check for voltage at coil. Thanks for all the help.

Rogers3232

And i live in iowa so emissions do not matter

JRCivic1

OP, I am not mad at all... the bold print was for emphasis. The fact that you are not bound by any emissions requirements makes this project much more open to different solutions... ideally, the best choice would be to use the '99 Civic EX engine harness, an OBD-2B -> OBD-1 ECU conversion harness and a '92-95 LS ECU. Many home DIY Swap people incorrectly use different engine harness combinations within the '96-00 Civic chassis and create all kinds of wiring problems for themselves that are super challenging for us here to assist you with without seeing the car up close. Since this is nearly impossible, good close up photos is the next best thing.

Assuming that you do have the original '99 Civic EX engine harness, it should be essentially plug and play all across the engine except for the distributor and CKF sensor near the alternator. However, if you follow the plan of parts that I suggested above, the CKF will not be needed, so we can focus on changing the dizzy plug and lengthening/shortening any sensor plugs needed. If the Civic was originally automatic, then we may have to deal with an IACV plug and type change, but we can work through that as well.

So first up... pics of all plugs at the ECU... include those that come in from the engine harness side (there should be two on a manual harness), the green "crossover" plug and the last ECU plug that is part of the under-dash/chassis harness. IF you have more or less than what I have just described, we need to solve this first before we conclude that any parts in the engine bay are bad.

I think you mean 94-95 LS ecu

92-93 are still a b18 and are obd1. PR4.
What he needs is a 99 P75 ls ecu and to provide pictures and better information.

tony_2018

obd1 better tuning options. who doesn't want that.

People who can't figure out how to get a stock engine to run.

Rogers3232

I can most definitely figure out how to get a stock engine running I have a couple job hear from someone swap that is unfinished and I'm trying to figure out I've never done this swap for and this is not a stock Honda set up clearly now that that's a side to answer a previous question I have voltage at the coil 12.11

Rogers3232

The only thing I have been trying to figure out is what things I need for this swap what ECU for this motor I have and if anything needs to be changed for the wiring harness or if I can just buy a different wiring harness that is all I'm trying to upload pictures right now they're all on my profile if they won't upload to this thread

JRCivic1

This would be ideal as far as I am concerned, but the '92-93 PR4 ECU would work "pretty well" also.

The '99 P75 still has OBD-2A plugs, so the OP would still need an adapter harness for it to work. But remember that there may be other potential issues that the OP hasn't mentioned like custom exhaust without a cat, converting the CKF wiring, and emissions related stuff at the charcoal canister. All I am saying is IF you are going to buy an ECU conversion harness, why not make it easy on yourself ???

Rogers3232

I have been trying to upload photos to this thread bit it will but i dont see them the are uploaded to my profile. The car has a 2000 b18b1 in a 1999 civic with a 1992 1993 integra ecu. Motor has has header and full exhaust has 02s installed in it just bot hooked up motor is getting fuel coil has power but no spark so im going to replace coil and see of i have spark. But do i need to get a newer ecu for this motor?

There are no pictures in your profile or anywhere so until you figure out your picture issue we can't help you with what we can't see. A 92-93 ecu will not work without a conversion harness. If you need to pass emissions or inspection with an obd2 port then you will need another ecu.
