Checked voltages today.
5v at map sensor (boost)
0.83v at both coolant temp sensor and fuel temp sensor
Decided to swap the engine sensor harness and I'm getting the same readings. Idk what the coolant temp sensor should read for voltage honestly. Hopefully the harness did something, otherwise I'm sure it's be a bad ecm.
