When you crank the engine do you see fuel spraying from injectors .if you dont check for power at injector connectors one side should power and the other will be ground controlled from pcm.you can test with a 12 volt test for both. first test with test light grounded for power then test with test lead clip to battery to pos to the other wire from pcm while cranking engine light should flash.if it does turn key off again lean over tbi and have somone turn key on and listen for fuel circulating through tbi unit if you hear it without cranking engine replace fuel pressure regulator.
