Was the battery recently disconnected or run dead? Try holding the gas pedal down 1/4". Also try turning the ignition switch to "run", wait a few seconds, turn it off, do that again, wait a few seconds, THEN try cranking it. If that works, suspect fuel pressure bleeding down over time. Do you hear he fuel pump run for one second after turning on the ignition switch?

You're welcome. If the battery was low enough for the Engine Computer to lose its memory, here's a copy / paste description of the relearn procedure: . . . lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
