I have a 1992 Honda Civic DX with Auto trans. From time to time when
it sits for about 8 hours in a sunny spot when its about 70-75F
outside it will not start. The starter will just crank. If I proceed
to remove a spark plug it will start and run on 3 cylinders. I shut
it off, put the plug back, and it starts and run perfectly on all 4
cylinders. This has happened 3 times now and I don't have a clue
why. Any suggestions would be appreciated.

Thanks Paul.

have you replaced/resoldered the main relay? It has a history of temp
related intermittents.It probably cools down while you are messing with
your plugs. see www.tegger.com (the relay runs the fuel pump;without enough
fuel pressure,the fuel injection doesn't work,motor doesn't run)

Why are you pulling a plug and trying to start it on 3 plugs,anyways?
What's that supposed to show?

It really is the main relay. Just fixed mine after dealing
with it for a long time.

I was pulling a plug because the first time it wouldn't start I
thought maybe I wasn't getting spark, so I pulled the plug and hooked
it up to the wire to see if the plug would fire, and to my surprise
the car started. But now that I know what the problem is I wont
continue to do that.

Good idea, Paul.

Meantime, until you get it resoldered, you can put the ignition switch
in position II and smack the dash on the left side of the steering wheel
(if you're in North America). You'll hear the fuel pump run for two
seconds and then you can start the engine. Filling the car with party
ice will accomplish the same thing, but takes longer.

Resoldering is fine, and will probably outlive the vehicle.
