    Hey guys. New to the board. Just finished installing all the obd1 conversion stuff ( ecu adapter, dizzy adapter, 94 obd1 ecu, 94 obd1 dizzy, and 94 obd1 intake manifold, and a brand new denso o2 4 wire.) So the install went great. . . But it wont start. I have spark, i have fuel, a checked every connection with a multimeter( dizzy, fuel pump, map sensor. . . Etc.) And everything checks out. . . Yet still no bang.

    Somebody help. Im out of time, patience and money.

    All of this went onto a 90 da integra b18a1. Im pretty dang sure the wiring is right but im flustered.

    Main relay?
    Ignition switch?
    Bad ECU?

    Ok so. We went back to the basics once more and it seems we now have no spark. further investigating shows that the dizzy harness was wired wrong. Two pairs of wires needed to be flipped, so i did that. Then we still had no spark. So we resistance checked the coil and the ignitor. The ignitor checked out fine but the coil had really low numbers, 11.2 resistance when it should be much higher (or so says hanes ). So out with the coil and i will post the results of the new coil in an hour or two. This is lucid.

    Thanks for the reply. The ecu is good, tested it in a buddies obd1 civic. Tested the main relay and that's good too, even tried a spare one. Im also thinking the ignition switch is cool as everything was kosher when it was obd0. Im hopeful that this new coil and the rewired dizzy adapter should be our ressurection. The only thing im concerned about is the distributor itself. It appears to be oem but i've been told that if its a remanufactured one then the wiring could be different for the orange and white harness wires. I guess we will see if it eats another coil. Who knows if it even ate the first coil or if it came that way. Eff all of these variables.

    So i finally realized after much stress and testing that the supposedly good condition distributor i purchased off of ebay had a bad coil and a bad ignitor. You wouldn't believe how insane that distributor made us. The wiring adapter for the dizzy wound up being perfectly fine so i had to go back and resolder and heat shrink that. . And oh yeah, the obd1 map sensor i had was dicked. So a quick replacement was near, luckily presented by my buddy carson. The distributor i got was however confirmed to be oem and not a reman. Good stuff. So tomarrow we get the timing light out and scuff some of the mild rust off of the timing notches so we can hopefully dial in the dizzy. Can't believe its finally running. Will post again after the timing session tomarrow but we got it running and worked all the codes out so woo hoo!!!!!

    Ouch! Distributors are the one thing you should really spend the cash on to buy from a verified source. My builder doesn't even like my buying distributors from AutoZone- but they've always worked fine from there.

    Well she runs like a top. No codes and true happiness. Obd0 is crap. Obd1 is next to godliness. Here comes a 2 bar map and boost.. yeah
