Car: 98 Accord Ex 2-Dr V-Tech 3.0, 160k,
Problem: Intermittant re-Starting problem, only after after driving
Occurs maybe 5-10% of the time when tried restarting
Starter Cranks fine, turns engine fast, no warning lights, full tanks to 1/4
Background:
Owned for 1.5 years and started noticing problem last summaer (9 months ago)
Starts 1st Time after Over-night sitting
Now and then will not re-start after driving.
Let the car sit >30 min and fire's up in 1-2 sec
Noticed mainly during 'Hot / High Sun Exposure',
But today after morning drive for 12 min would not re-start (temp 30F) until it sat for > 30 min. Then restarted fine and within 1-2 sec of cranking. And re-started, restarted, ... atleast 10 trys no further problems

To-Do:
Have searched the HAF and will double check Fuel Cap, Fuel Pump & Relays
Also will check Plugs, Coil, Dist caps, .. the simple basic stuff
Take to Parts House for Fault Code Check

But did notice 1 thing from under-hood check
the IAT Sensor is 'Wet' fairly clean looking oil, will spend some time to check the threads / seal or sensor cracked.

Any other focus Debugging Steps would be appreciated

tks
