For the past couple of years, once in a while, say once very couple of
months my Honda CRX won’t start.
-It does not seem to matter whether engine is hot or cold. It has done it
in the morning as well as after lunch at work.
-Starter is OK engine is turning normally but seems to me that none of the
cylinders are firing at all.
-After several failed attempts to start I do not necessarily get any codes
on PCM.
-Sometimes after repeated tries it may start but usually it won’t start no
matter how much I try. Then I’ll try again the next day or a few hours
later and it will start normally.
-I’ve had an occasional code 06 indicating faulty water temperature
sensor. I’ve measured resistance of sensor and seems to be within spec.
When I clear the code many days can go by without the light coming back
on. There seems to be no correlation between the light coming on and the
car not starting. Besides I would think that even a bad temperature sensor
would make the car run poorly but I would not think it would make it not
start at all. Am I wrong?
-Otherwise, on any other day or once the car starts then the engine runs
fine, MPG is up at the usual 40 or so.
-I have had an occasionally unstable idling where sometimes the idle speed
is somewhat higher, say around 1000-1100rpm. Now that I can see how it may
be related to the water temperature sensor.

Any ideas? I’ve even took car to the auto mechanic but he told me that he
could not do anything unless I briught him the car when it was not
starting. I once finally towed it when it was not starting and once we got
there it started normally?!

Thanks
