I tested crank position sensor (cold) and it measures 800 ohms.

While testing, I noticed the small vacuum tube at the EZL had become disconnected. That vacuum connection does the advance/retard of ignition timing. I don't think it can cause the intermittent no-start and stall trouble I'm having though.

So...time to gamble.

Should I buy:

Crank position sensor (even though resistance measure is within spec)
or
OVP (even though looks good, fuses good, no rattling, no CEL, no ABS light)

Or continue looking for something more definitive?
