Cadillac Repair: Cadillac Deville 91 4.9L V8 wont start, cadillac deville, control circuits

Question
My car will not start or crank. All the inside lights come on and power windows and locks work. I have had this problem in this past and if you let it sit for a while it would start now it wont. Here are the codes I got via the method of holding down the off and warmer buttons.

8.8.8
..E
E52
. 7.0

What do these mean?

Answer
888 = this just means that you are accessing the computer diagnostics and that all the digits on the display are working.

E = this is where your ECM computer would show fault codes if there were any they would display.

E52 = you disconnected the battery at some time.

70 = a procedure to test the cruise control circuits and to go into further disgnostic within the computer.


Since all you have is E52. You have NO fault codes.
