New motor not starting

    After putting the new motor and gearbox into my car the motor cranks but just wont start. I've put all information I think to be useful to you guru's out there to hopefully be able to help me out. please take the time to read through it, any help or idea's would be much appreciated.

    Recently I purchased a 3S-FE with a 5speed manual with intentions of taking the gearbox off and putting it on my existing motor. When I received the motor and gearbox I done just this only to find that when I took the gearbox off that the flywheel's were different (the one I purchased was 6bolt while the other original motor was 8bolt). As it turned out the 3S-FE that I purchased (out of a Corona) was quite different in places to the 3S-FE I previously had.

    I then decided we would just put the complete motor and box that I purchased into the car.

    Once the motor was already in the car we found out that the motor and gearbox had been sitting for 8years being turned over by hand regularly but hasn't been started. This could be related to the problem.

    Things that I had to change:
    Exhaust manifolds (put the one's from original motor on)
    Thermostat (from the original motor as the plugs were different)
    Dizzy (from the original motor)
    The little electronic box that mounts off the throttle body (from original motor)

    Since my car was previously auto we also had to change other things such as gear lever cables etc. We also took out a little silver computer that had a yellow sticker on it saying 3S-FE. We believed this to be the auto gearbox computer.

    We also had to wire up a switch from one of the plugs (Dads an auto sparky so he done this bit) so that the car thought it was in neutral and could start.

    After doing this we could get the motor cranking over. Which was pretty weak. So we then hooked up a huge truck battery to definitely rule out the chance of not having enough power. It tried to start but it only lasted a split second before it shut off again (as if it wasn't getting enough fuel to continue running).

    I then went and grabbed some fuel from the local to insure that it did definitely had enough fuel. Unfortunately results didn't change.

    What I'm thinking is there might be something that needs to replaced or cleaned up because it has been sitting for so long? Like I say it turns over no problem. But has some problem firing.

    Please anybody who has half an idea please share it. I just want her back on the road :sad .

    Thanks in advance, Harding

    has it started for even a second since then? or was that the only time? Have you checked if you have spark?

    :lol....... onya Scotty, it's not the first and won't be the last time someone does it.

    I dragged up an oldie recently about an AFM to ask questions about the inner workings because it had it's top/bottom off as it's not something you see everyday.


    You however, are excused and there's the door :lol

    Actually I think this thread was dealt with before and got deleted in the crash
    No harm in opening coffins afaic - there are always others asking the same questions

    You're talking about my old car?

    Why change the motor? It had been honed and a new headgasket fitted not long before I sold it.
    It was powerfull and light on fuel, all you needed was a 5S-FE flywheel


    The auto has 2 ECU's, the gearbox ecu is near the gearlever, plug it back in and see if it starts.
    Loosen one of the pipes on the fuel filter or cold injector, see if fuel comes out when you try start it
    Hold a spare spark plug against the block to see if there's spark
    Did you swap the injectors? they don't like standing for years

    Note - JDM FE's use MAP, there's no AFM etc

    Not sure what happened to Harding, he hasn't been here in quite a while? - YUP last seen in 2010 so I don't have much hope for this car - fond memories though
