    Hey Guys!
    Recently I;ve been helping a friend do an ls/vtec swap. B18B block and P72 head.
    Anyhow, his car was originally a GS - auto.
    So we converted it to 5 spd using all the mounts, pedals, intermediate shaft bla bla. Thats all fine and dandy.
    Now, today we try to turn her over and we get nothing. The key wont come out of the ignition unless we disconnect the battery.
    The only logical problem is that when we removed the auto shit, we may have left it in drive or reverse so the car still for some reason thinks its in drive or reverse so it wont let the key go.
    Also, the motor wont turn over at all, no click no nothing. We tried a new battery and nothing.
    We figure we have to jump a plug by the console to make it think it's in park.
    Which at the same time makes no sense because we removed the auto control unit from the area where the clutch pedal sits in.
    We're ready to go and this is the only thing holding us back.
    If anyone has any information it would be grealt appreciated.
    Thanks alot.
    Dom

    Oh the car set up is
    Obd1 - obviously
    P72 ECU chipped
    b18B block
    P72 head
    YS1 tranny

    thats all that should matter.

    did you wire up the clutch safety switch or w/e its called?

    it doesnt let you start the car without the clutch engaged, that would cause your no-start problem

    is the ECU the manual or auto version (idk for sure, cuz im somewhat new at hondas, but i know there are 2 different ones and i'd think it'd have something to do with that)

    just some thoughts untill someone more knowledgable chimes in

    Thanks for the suggestions.

    The car does not have a neutral switch for the pedal because it was automatic. The car needs to be in PARK or NEUTRAL to start. I think the switch is by the console and I just have to jump a couple wires and it will work. - I hope.

    As for the ecu, P72 only came 5spd...no GSR ever came auto....

    There must be a shift interlock solenoid in the steering column. I'll take a peek in alldata for you.

    Well when you removed all the auto stuff, did you unplug or cut it? did you ground the wires that you are supposed to? Ive done the auto-manual conversion on my car, Ill try to get some pictures of the wiring.

    I didnt wire the reverse lights or the clutch switch as I did not plan to retain cruise control, if you do however you will need to wire these up.

    Did you shim the mount as you are supposed to? If you didnt/dont you will have a real bad vibration, not to mention the engine will sit cock-eyed.

    FYI - the intermediate shafts are different between autos and manuals, so you will need to use the manual half shaft.

    Thanks for the replys.
    I got the car cranking...but no start :(
    I found the timing was off by one tooth, corrected it and still nothing.
    I have spark, fuel and plenty of air.
    I even tried to pour some oil in the cylinders and nothing.
    After crankng for a while I get a loud POP out of the intake....
    Also, sometimes while the motor is cranking it sounds like its getting harder on one stroke and then cranks normally again...
    Any ideas?

    same thing happend to mine when i had it going
    it was the main relay under the dash for me.. this is EXACTLY what happend..
    i know its a common thing to go out in these hondas.. you can pull the relay out, and check the solders on the board of it (you have to pull of ht elittle cover thing first) and if any of 'em look cracked or 'dry' i'd resolder 'em.. most people suggest that you resolder all of them, but you dont have to.. i did and mines working great now!

    when i did my ls swap in my crx that was the problem i had and i waould say check your plug wires as for making the car think its in park you have to cut and connect a couple of wires in the center console check rywire.com or something like that they have the auto to manual on a crx it might help.

    Another no-start thing you might check is the plug gap. Hondas get cranky when their plugs are off.. Just a simple fix, do it while you are checking your plug wires.

    Still no start:(

    We needed up just getting a ITR and dropping it in.
    Weird thing, friday, after cranking for some time, the motor started.
    Twice.
    Yesterday, we finsihed the rest of the car, the exhuast, shift links, bla bla.
    I extended a few wires for the TB mounted map sensor and tried to figure out the vacum lines.

    Does anyone have a link to the vac lines for a 92 5spd DA?

    The motor wont start, but if you crank, it just barely sputters and wants to start but it just wont.

    We bought a brand new main relay which why we think the car started...
    any ideas?

    Try switching the MAP Sensor plug and Idel Air Control Plug.
    Had these switched once by mistake the car ran but barely and was extremely rich.
    The plugs use the same connectors and could easily just be mixed up.
    The ECU reads nearly the same voltage from those sensors, so the car will run but very rough.
    Just a thought.
