    CAR WON'T START:

    Starts on page 4

    OR MAYBE THEJLEVIE CAN HELP YOU!!:

    The DME, engine harness, coil, and CPS are all that is required to run the engine. The car provides power to the coil and the START input of the DME via C101 and the fuel pump relay output is routed via C101. Since the ICV doesn't buzz with the key in RUN, my first suspicion would be that the DME has no power or isn't getting a START signal. A trouble shooting guide is:

    For the engine to run the following conditions must be met:

    Power on DME pins:
    27 Start Input
    18 Un-switched Power input
    37 Power Input from Main Relay

    Ground on DME pins 2, 14, 19, 24

    Timing data from the CPS on DME pins 47 & 48 from a rotating engine

    To have spark power must be present at the coil positive and ground pulses
    from the DME's pin 1 must reach the coil negative. Power to the coil is
    controlled by the ignition switch via C101.
    When checking for spark, use the output lead from the coil to eliminate the distributor, rotor and plug wires.

    To have injector firing power must be present at each injector and ground
    pulses from the DME's pin 16 (Bank1) and pin 17 (Bank2) must reach the
    respective injector bank. Note that the injectors are wired as two banks of
    three. With cylinder 1,3,5 being bank 1 and 2,4,6 being bank 2. Power to the
    injectors is controlled by the main relay.

    The fuel pump relay must have power on pin 86 (relay coil) from the main relay
    output (pin 87) and power on pin 30. The DME will ground pin 85 to turn on the
    relay and power the pump(s) via pin 87. Of the above, only the fuel pump power
    is fused. So if the there's power at pin 87, but not at the pump, check fuse
    11.

    The main relay and DME pin 18 receive power from the smaller of the to wires
    that connect to the battery's positive terminal. That wire incorporates an
    in-line fuse. When the DME is presented with a start signal, it grounds the
    main relay pin 85 and furnishes power to the fuel pump relay, injectors, and
    DME.

    Troubleshooting:

    Disconnect the battery and the DME.
    Then:

    1) Disconnect the coil negative and check continuity from that connector to
    DME pin 1. Also verify that from DME pin 1 to ground is an open circuit.

    2) Check the resistance across DME 47 & 48, which should be 500-560
    ohms. If the CPS is dismounted, the resistance can be seen to change
    from about 500 to 540-540 when a ferrous object is brought to the face of the
    sensor. Neither pin should be grounded.

    3) Check for continuity from DME 36 to main relay 85 and from DME 3 to fuel
    pump relay 85.

    Reconnect the coil, remount the CPS (air gap should be 0.040"), plug the
    relays back in, reconnect the DME, and connect the battery. Then do the
    following checks:

    1) With the key off, verify that power is present at DME pin 18 and main relay
    86 & 30.

    2) With the key on, verify that power is present at DME pin 27 and pin
    18. Power to pin 18 is from the main relay and there should be power to the
    injectors and fuel pump relay.

    3) With the key on, verify that no voltage is present at the DME grounds (2,
    14, 19, 24).

    4) Verify that power is present at the coil positive and at fuel pump relay
    pin 30. Those get switched power from the ignition switch via C101.

    The engine will start and run (if poorly) with only those connections to the
    DME in place. The other signals from Cylinder ID, AFM, temp sensor, etc., are
    necessary for proper operation. But they won't prevent the engine from firing.

    IMPORTANT:

    A power check means seeing a voltage within about a tenth of a volt of what
    you measure across the batter terminals, which should be at least 12.6v on a
    charged battery.

    A continuity check means seeing less that 1 ohm of resistance.

    An open circuit means seeing a resistance of at least 100k ohms.

    A good quality auto-ranging Digital Multimeter will make these tests much
    easier.

    After so many times people asking what bulb goes where, I decided to create a comprehensive list of lamps and where they are used in the car. This should be fairly accurate. Please post any corrections in this thread and I'll update the chart.

    If a bulb is not listed here and it's one of the tiny lamps, it's most likely
    a 2721 or 2721MF. Some switches have replaceable bulbs that are not listed.
    In a number of places, the 2721 lamp is fitted into a socket with wire leads. For example the rear ashtray and the auto shifter. If yours breaks, the repair part is PN 64111366170. (Thanks H.J. 1981)

    The OBC panel backlight light bar is expensive. If you're handy with a soldering iron, you can try replacing the lamps yourself. From what I have been able to gather, the lamp specs are bi-pin mount, T-1 3/4 base size, 6.0V/.02A. The catalog number I see associated with those specs is 7328.

    BMW EBA document (9750880) for an is style spoiler. I don't know for sure if the same drill pattern is used for the M-tech spoiler, but it's likely it is. Sorry, but it is slightly over the size limit to upload directly here.
