I had a similar issue when changing my alternator, turned out that the ground wire going to the bottom of the motor didn’t have a nut on it and it wasn’t making a good ground connection. Just a thought on something to check
With the same MAF and injectors it should still idle. As mentioned go over your work and make sure everything is sealed. You might need to check and adjust the TPS voltage while you're in there.
I checked ground wires they are good I have a predator programmer that was used to program the car years ago with the Eaton and factory stuff don't know anything else aout that and I don't know how to manually check tps voltage
Looks like a fuel problem it had fuel pressure till now I didn't have a way to measure how much but I'm guessing it wasn't enough I put new fuel pumps on it something must have went wrong fuse is good but each time I try it gets less and less fuel pressure
