Come on guys. I know you can help me with this,or at least give me a generality,like"run a line from the back of the IM to the MAP,then from the top to the charcoal canister and it should at least run" or something along those lines. Any helpful info at ALL would go a looong way for me.

Ive read alot of in-depth articles here,and i know there are some really knowledgeable guys here,so flex your brain muscles and help me figure this out haha. First off: which intake mani is that? Second of all: what are the basic requirements for that intake manifold and map sensor to play...

And does anybody know what this effing hose connects to? It disappears into the firewall right underneath where the charcoal canister goes.

Alright, so after finally getting it to start, (thanks again guys) I'm plagued by vacuum troubles. Idle was too high(15-1700) so I rearranged a few vac lines and now idle is absurdly weak, nearly dying after gas is applied. Charcoal canister is there, but not hooked up. I have (what I assume) a...

It lives! Replaced the rotor and dist cap, swapped OBD1 PR4 for OBD0 PR4 ecu, turned the key and it started right up.:clapping: Thank you guys for all the help and tips. :thankyousigna2:

So I traced all the wires from the distributor plug to the ECU, and all were connected right, except for B11/12 (CYP sensor input/signal). On the OBD0>1 harness they weren't connected, so I connected them to their corresponding pins. I was excited thinking that I found the problem, but turned...

Thanks man, sounds good. Here's my line of troubleshooting thus far, somebody point out if I've missed a step or asumed something incorrectly; I took off my fuel rail, and was greeted by fuel. (proving engine is getting fuel.from pump) If i try to get sparks from spark plug wire to ground...

Just an fyi, I knew only the very basics of an engine when I joined this forum(read my first post), and tried to figure as much out on my own as possible. I am a newbie to the engine side of things, and I'm trying to learn as much as I can as fast as I can, so if I'm not grasping something, or I...

I started going through all the wiring, trying to tie up loose ends and make sure everything is going where it should, and I noticed my distributor has the round 7 pin plug (for an Si harness,but assuming prev. owner tried to do mpfi conversion), but has 4 injectors,dpfi manifold/tb, and was...

I tried doing as much research as possible before asking, and from what I've read it seemed so, but i just wanted to make sure. On a side note, there's a PR4 OBD1 ECU with an OBD1>OBD0 harness on it hooked up to my engine harness. There's also another PR4, but OBD0. Would it be more beneficial...

1991 honda civic lx sedan.

From what I've read, I would just have to do the dpfi>mpfi conversion, right?

I have the opportunity to pull a 91 LX sedan harness, but it's automatic. Also, it's an LX(mine's a DX). I assume that it being a different trim, auto and not manual, and a sedan versus a hatch mean that it's either incompatible, or a boatload of work to mod it to work for me. Any thoughts...

The O2 sensor right where the exhaust connects is disconnected, as well as the water temp sensor. Would that have any effect?

So pulling the plugs and disabling fuel injectors did nothing, and I looked in the cylinders after removing the spark plugs, and they weren't flooded. Injectors are getting power, but spark plugs aren't sparking now. I tried to get sparks to jump from the boot to ground and they won't. Dizzy? I...
