Hello, long time lurker, first question.

I was trying to trace why i had no power at the IAC valve connector.
things i did: removed IAC, unplugged connection block near driver side strut tower, unplugged a single connector next to connection block, turned key to ON position for several minutes while i probed the ECM pins for information on the engine temp. sensor (readings ok).
I put everything back together - went to start the car but all it would do is crank. sprayed starter fluid and it hit for a few seconds. I can hear the relay click when key is moved to ON position, BUT i no longer hear the humm for a second or two like it did before. Fuse #1 and #11 are good.

Finally the question (s)
Is there another fuse or relay to look at?
Would the fuel pump itself get fried just because i had the key in ON position for less than 10 minutes?

Is there a way to test/power up the pump without pulling it out?
It is a new pump with less than 2k on it and its a bit of a bear to r&r that thing.

Thanks for any suggestions
