Well I am new n lost here but still have same issue with my girlfriends  ( 2010 FORD EDGE LIMITED EDITION 3.5 , V6 ) as it STILL Won't Start  I purchased a small code reader for her EDGE and the code it showed was ( 1633 ) where Ford dealer service says is  Insufficient voltage for the Keep Alive circuit  Ford associate said possible voltage regulator ( ? )  Tried to get the alternator out through passenger side wheel well but could Not manage  So I will have to try top side removal  however the AC line's look to be an issue ... ???? Could Anyone comment  L.F.

My girlfriends Ford edge limited edition front wheel drive V6  Wont start.  Have replaced spark plugs, ignition coils, fuel pump assembly.  Purchesd a OBD 2 Code reader which said Fault  1633  Ford says its the " Keep Alive circuit " says insufficient voltage "  makes no sense  checked Many fuses  still vehicle cranks but Won't start  Any help would be Very Much appreciated  Thanks  Larry F
