Codes p1895 and p1625 are the main ones I'm worried about, I drove it home and the next day wouldn't start, and it doesn't crank over. Lights and everything come on but it wont start and we need to move it because it's parked 2 blocks away on a cross street. They will tow it. Any advice please help?

Codes p1895 is for a bad TCM and the p1625 code is for a bad throttle pedal sensor but I have seen if you clean the throttle bore this code might go away so you can get the car moved. Also, check all fuses, here are two guides to help us:

Check out the diagrams (below). Please let us know what happens. You can try clearing the codes as well.

Will removing the ECU fuse out for minute or two will that reset the codes or sensors that caused limp mode, possibly?

It sounds like you have an oil pressure issue, I would remove the oil pan and clean the oil pump pickup when can get clogged up with gunk. This is a common problem, please do not start a new question with the same problem, continue with this thread until resolved.
