Need help

[weatherfordjacey]

So I tried to replace my oil pressure sensor the other day and the 90 it was in broke on me got the broking piece out went to a junk yard found a new one put it in with new oil pressure sensor hooked everything back up and it won't start sounds like flywheel is missing some teeth did the old paper clip diagnostic came up with ignition control module code and fuel relay low voltage

I'm stumped don't really know what to do right now it's my daily driver
