try holding the pedal down slightly. That will bypass the ICV. If it starts then change the ICV. If it won't start check the small lead for voltage coming from the battery, on the 6 cyl cars there is a 50 Amp inline fusible link that can corrode.
Failing that tap on the main relay and the fuel pump relay, pull them out put them back in... etc. And check all fuses.
Good luck, it's most likely one of those things.
Performance one step at a time.
