Ok, first off either replace or properly check the "ECM B" fuse with a meter. A visual inspection is not good enough. This fuse powers the fuel pump relay and the oil pressure bypass switch. Let me know the results of testing/replacing the fuse and we can continue from there.
Do you have a meter to check voltages?
Sure thing! Lower left of the fuse block as shown in the picture below.
