Make sure it's all the way in park turn the key on let all the dash lights go out then turn the key over then if that don't work I will suggest checking spark plugs for other signs of problems

Bad plug or broken wire at the plug, at the alternator. Pull the plug off the alternator. Turn the key on and check for power and ground at the leads. No reading, probe the wires a couple inches back. If a read there fix or replace the plug. If you have a 3 wire plug, best to use an ohm meter. Test each wire separately. At the pin and a couple inches back on the wire. This test may include testing the wire back to the PCM and fuse panel. You'll need wiring schematics for this. The PCM is what fields the alternator to charge and supply power when the engine is running.

On my s1s10, it was a blown fuse under the hood and front wheel hubs needing replaced. The bad wheel hubs were throwing abs and traction systems as well as no cruise. The noise from the hubs confused the abs sensors until they got new ones. Everything is one piece nowadays.
