• 94 Acura Integra flooding

    From The Real Bev@21:1/5 to All on Tue Jul 6 21:24:47 2021
    Problem started a few months ago.

    Starts fine when it's cold. When it's warm, turned off for ~15 to 39
    minutes and is still warm, it cranks for a long time as if it's flooded
    and there's a strong smell of gas -- but no leakage to the ground. When
    it finally catches, it runs really slow and you have to be really
    careful about feeding in more gas for perhaps half a minute.

    Tapping the distributor while cranking resulted in an immediate start
    once. So did leaving the gas cap loose a few times. Sometimes it
    starts OK when warm, but mostly not. Replaced the fuel pump, but no
    change.

    Now he carries a spare battery and jumper cables just in case. This is
    maddening. Any ideas?

    Everyone crashes. Some get back on. Some don't. Some can't.

    When it happens, is there spark?

    Doesn't seem to be.

    When it happens, is there any voltage on coil primary?

    He hasn't found the coil yet :-(

    SOMETIMES it starts when hot with no problem at all :-(

    I've never heard an engine sound like it does when it catches but is
    running really slow and trying to REALLY start.

    Measure it! Make sure!

    While he's looking, have him locate the TDC sensor and/or crankshaft position sensors. Those also need measuring.

    Maybe there's no spark, maybe there is poor spark, maybe there is plenty of spark but the timing is way off.

    Check ground connections.

    It runs fine once it starts. Tonight it started hot with no problem.
    Drove home, turned it off, tried to start it again immediately. CURSES!

    He says this is a Honda trait -- intermittent failure. If there was a
    complete failure you'd have a shot at diagnosing the problem!

    Glad I bough a Toyota.

    Sounds like a cam or crank sensor going bad.
    Pointed out by Scott, too.

    I've been looking at failure symptoms at various sites. Poor running of
    one sort or another seems to be indicative, with intermittent starting
    down near the bottom. Of the two, the crank sensor seems to be closer
    to reality.

    Further tests -- Fine spark on all plugs. Starting fluid does nothing
    except ONCE it made the engine race when squirted directly into the
    intake tube rather than at the air cleaner. Except for that, no
    reaction. Tapping various things under the dashboard sometimes allows starting, as does tapping various things under the hood. No
    repeatability. Sensors are too expensive to buy on spec :-(

    I wish I trusted even the GOOD mechanic, who was unable to make my 88
    Caddy stop trying to kill me with its auto-throttle. He said the only
    thing left to try was a throttle/computer part that wasn't even
    obtainable from junkyards. Only solution was crushing, for which the
    State of Kalifornia paid me $1K.
