The ATP is what indicates it is in park. Is the ATP light on? It would prevent the starter from engaging but that doesn't seem like the issue. Let me know.
As far as the injectors, when the key is in the run or start position, the injectors should have power. Go to the fusible link box under the hood and confirm fuses 62 and 63 are both good and have power to and from them. Since you have spark, I assume fuse 62 is good. However, please confirm it for me. Additionally, make sure there is power available to both with the key on.

If they are good, I need you to check the ECCS relay.

Let me know. I need to know that power is where it should be. If it is, then we need to determine where the break is after the supply.
Take care,
Joe
