    Yup, our '88 245 is still very not starting.

    I'm thinking about trying this theory others have had regarding
    cleaning the throttle body on the car.

    Before, when the car ran symptoms that pre-cluded this no-start
    included:
    -very, very poor fuel mileage.
    -hard starts
    -uneven idle (missing). This would even out once car reached operating
    temperature.
    -dark black exhaust, very noticeable (unburned fuel, big time)
    -the engine would stagger, almost stall, after running at high RPM. A
    great example would be if you revved the engine while parked. While
    RPM lowered, it almost stalled before it quit.
    -Adjusting the idle speed screw does nothing.

    Now...
    -injectors are working
    -new spark plugs, cap, rotor
    -plugs are soaked with fuel, nothing is burning.
    -cranks really well, not even close to catching.

    I see alot of mention of trying to clean out the throttle body, I may
    give this a try, any ideas??? Right now I'm so frustrated I'm thinking
    of installing the engine+tranny from my old 1979 in this car, then at
    least I can trouble shoot something I understand (B21A vs B230 in newer
    car...)

    Thanks for the help, I really appreciate it!

  3. Compression test, verify ignition function... Timing chain?

    Disconnect the O2 sensor. If it's shorted to ground it will force the
    fuel computer full rich.

    Pull the vacuum hose off the fuel pressure regulator and be sure that
    the diaphragm is not ruptureg and dumping fuel directly into the intake
    manifold.

    Checked the air filter? If it's badly clogged, it can cause a rich
    condition.

    Also check the catalytic converter; it could be clogged.

    The one thing I'm not seeing mentioned here is the very first thing I
    would have checked, the air mass meter. Try unplugging it and see if the
    engine starts, if it does then that part is bad.
