Honda EU3000is will not start

Starting a new post.

Bought a used 3000is, was told it has been sitting for 1yrs.

Things that I did to it:
*Carb rebuilt
*Fresh new gas
*New spar plug
*Fresh oil (FILL TO MAX & OVERFLOWED)
*Check valves to make sure it open & close

Symptom: Oil Alert will flash/blink when try to electric start or pull start

Every 10-15 pulls, it will back fire one time. When doing testing the spark plug, I will see the spark 1 or 2 time before the oil alert flash/blink and no more spark. If try to restart same thing, will get spark for about 1s, then no more because oil alert flash/blink.

Measure oil switch to ground = open
Measure yellow wire to ground = open

Anyone has a service manual for the EU3000?

At this point, I suspecting the a faulty ICM, but don't know how to test it. Or the Key switch.
