You need fuel, compression, and spark for the engine to run. Initially, I think some of us thought the engine was not turning over at all, hence my comment re being locked up.
Do you know how to do the key dance to obtain codes?
Start with the ignition key at off. Rotate it quickly from off to run (not start) 3x in 5 seconds. You'll end up with it in Run. Observe the odometer display. If there are codes, you'll see them there. At the end, you'll see pdone.
