Alright to start, names Kevin I just opened an account. I have a 95 accord lx of course obd1. The b2 crapped on me and I was able to get a really good deal on a 96 f22b1. Not realizing it was obd2 I dropped it in harness and all. It fired right up, keep in mind I'm still using my p0b ecu. But its weak and in limp mode with no cel. Sometimes randomly I will get a misfire and code 9 pops up. So my main question really is, should I just get a obd1 to obd2a jumper and a p0h? Will that take care of it.. Or how can I stay obd1. I read I could just throw a obd1 dizzy on and wire my sensors from my oil pump area to it. But haven't found a write up that describes my exact dizzy plug( one plug 5 pins) any help will be greatly appreciated!

Nobody has some insight?

Anyone able to give me some help?!

 

usually you use the new block as a replacement block only swapping over YOUR harness/manifolds/distributor. then if it doesnt work you did something wrong on install and need to go over your work.

for the code 9 you should probably just follow your service manual trouble shooting procedure, and usually when i get another engine at minimum i check that mechanical timing is correct as well.

 

Thats what I should have done. But I wasn't aware this was an obd2 at the time and had already scrapped out my old obd1 engine. That being said I've done a lot of research and what I need to do is wire the ckp and tdc from the oil pump area for the obd1 dizzy instead of using and obd2 without the ckp and tdc. Or the easy option that I don't want to do is get the obd1 to obd2a jumper and the obd2 p0h ecu. I just need the wiring Info for the ckp and tdc on my 5 pin 1 plug dizzy connector.

 

You use your existing distributor and add two wires to your existing harness, vtec solenoid and vtec pressure switch however you need to use the obd1 b1 ecu. You can get a kit from axidworks, just google that. Then run the wires to the ecu connectors, pop open the back of the connector and slide in the pins and close the connector.

My guess is you're trying to use that 96 distributor. You should be able to get by by using your exisiting distributor until you finalize the swap.

You don't need to change anything else.

 

I can't plug an obd1 distributor into my obd2 plug. Also the obd2 vtec selonoid doesn't have a pressure switch. I either have to run my ckp and tdc into my dizzy wiring, by cutting the obd2 plig off and wiring in the obd1 plugs. Just dont know the pinout and what not if i want to remain obd1 or jump my ecu to obd2. someone has to have ran into this before. I can't believe it's so hard to get answers.

 

Your '95 accord is obd1 stock which means your harness has an obd1 plug. There are no "obd2 vtec solenoids". If it doesn't have one, then it was probably a euro model or a model that simply didn't have a pressure switch, which is rare but they are out there. You just need to pick up a vtec pressure switch and swap it on.

It sounds likely you are trying to use the obd2 distributor with your obd1 plug.

It's not hard to get answers, you simply are confused about what you need to do. If you are trying to learn, you need to really listen what I'm telling you.

Also, I can only give information based on what you are telling me. If the information you are supplying is incorrect then the information I'm gonna give you is not going to match up.

 

That's what I'm saying. I pulled the obd1 motor and harness out and replaced both engine and harness with obd2. The info I've gathered is the obd2 f22b1's did not have the oil pressure switch. Sorry if I misinformed or misworded something. But my problem remains that I'm basically running all obd2 except my ecu is still the obd1 non vtec p0b. I didn't really want to convert to obd2 so I was looking for ways to convert my obd2 harness to obd1. But it's probably going to save a headache to just go get another obd1 harness.

 

Replacing your stock harness is almost never necessary. The only difference between the two blocks was the different oil pump on the obd2 block that holds the crank sensor that you don't need when using the obd1 ecu. If you were going from obd1 to obd2 to use an obd2 ecu then yeah you'd want to use the obd2 harness, but all you gotta do is a couple wires/pins to your obd1 harness and you're good to go.

Nothing in your original post indicated you switched out your obd1 harness, if it did it wasnt clear.

 

Your righ, I apologize but let's make this as simple as possible. Car=95 accord lx Came with obd1 f22b2 non vtec, motor=obd2 f22b1 vtec, harness=obd2 f22b1vtec harness, ecu= original obd1 f22b2. Now that that's all clarified. how do I modify my obd2 harness to run obd1 dizzy and are wiring my ckp and tdc around back to the dizzy wiring.
