    Not Starting After Engine Swap

    My car is not starting after the engine swap. I know that it is getting fuel because I can hear the injectors hum if I push on the metering plate. I can also smell gas coming from the exhaust. I don't think that I am getting spark. I broke the connector on the side of the distributor when I put the engine back in, but not badly as the contacts still seem to be intact. I have also tried swapping ignition coils..

    I broke that same connector and my wires are intact too. My car runs fine with those two wires plugged in. Does it get spark if you hold the wires in place?

    Checked your battery voltage?
    You sure you've got all the wires from the ignition distributor on the right cylinders?

    Do you have a good engine ground?

    I think so, I took a picture before and arranged them in the same way.

    I cleaned and degreased the ground strap and where it mounts. The starter cranks fine if that helps.

    I think the order is (clockwise) 4, 3, 1, 2.

    That's a tad confusing.

    It's CCW 1342 on the 1.8 engine.

    Yeah, with the vacuum advance facing the passenger (right) side of the engine bay and starting from the 6-o'clock position, 1342.

    Would the computers from a us spec '82 and a canadian spec '83 be different?

    Far as I know, they are generally just a tad more apologetic.

    Why do you ask?

    The car I swapped the engine into is a 1983 canadian spec 320i. The engine came from a 1982 us spec 320i.

    I gathered that from your previous post
    I guess I should ask if there's a problem your car is experiencing. Is it a 'no-spark' issue?
    Did you test for spark at the plugs?
    *remove the fuel pump fuse while testing for ignition spark.

    *fyi:
    The Lambda control module is only connected to the fuel system.
    The Ignition control module is only connected to the ignition system.
    If ignition spark is the issue, make sure you have the ICM's brown ground wire attached properly to the engine block(not the starter motor!).
    If fuel is the issue, make sure the frequency valve is connected, including it's brown ground wire to the engine block.

    I'm not too up-to-snuff with the later models, but I hope that helps.

    Please refer to the ETM(linked in the DIY/FAQ thread) for your car if needed.

    I swapped the Lambda and ignition modules and it starts now. All I need to do now is switch the diff and driveshaft before I drive it.

    "Lambada" Module:

    If you invest in one aftermarket upgrade, make it the Lambada module.
