need obd0 help - 91 crx

anyone have experience with a code 8 condition?

my crx is flashing this and will not clear. it has a brand new
distributor & drives just fine. the check engine light is not on.

code 8 is supposed to be for tdc/crank sensor, but are there any other
conditions known to cause this? [for instance, code 16 is injectors,
but is usually caused by the main relay]

thanks!

agreed. i'll bet 90% of all throttle body/injector sales have been as a
result of code 16 replacements. the helm manual is utterly useless in
diagnosis of this fault because it assumes the main relay's functioning
correctly and sends you in a flow-charted wild goose chase that costs
serious money. the only point at which it /does/ mention the main relay
in the flow chart, in the '89 helm at any rate, it assumes it's a
cabling fault, not a relay fault.

if the motor starts, there's no symptoms. if it doesn't, it lights the
check engine signal & stores code 16. i've never had a motor cut out or
stumble with main relay problems once the motor's running.

I have! Sumbitch left me by the side of the road near Wapela
Saskatchewan. Just quit cold after coming all the way from Calgary.
Had I known then what I know now!
