I have tried holding the gas pedal down and cranking for a few seconds. It doesn't fire at all, it just cranks. I smell no gas when I do this either. I haven't tried cranking for more than a few seconds. I will warm the car up and let it cool down and crank with the pedal down.
As far as the IACV, I removed it, wiped it down to remove any deposits (it did not look too bad) and sprayed the shaft and spring with a little WD40 before replacing it. I don't know if the thing needs to be disassembled to clean correctly.
Thanks for the reply.

The same thing happened to my 93 es300 and the problem was the distributor, So it was replaced and the problem was resolved. Hope this helps. ;)
