Doesn't seem to be.
Measure it! Make sure!
When it happens, is there any voltage on coil primary?
He hasn't found the coil yet :-(
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.
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.
Ultimately (10 for 10 at least) the solution was replacing the coolant temperature sensor. The computer didn't see it while it was failing,
but ultimately it showed up. Replaced it ($25 or so mail order) and so
far so good.
I'm sure there's a rational explanation, but I don't want to think about
this any more :-(
Life was easier with thermostats and heat risers. Plus you could throw
one pretty far when you discovered the problem out in the middle of nowhere!
