ecm looks like a remanfactured one still code 51
 

Just look at ecm looks brand new think last owner got a remanifactured one and I took the ground out of battery to erase trouble code still code 51

Re: ecm looks like a remanfactured one still code 51
 

right from alldata:

CODE 51 - FAULTY MEM-CAL OR PROM PROBLEM

CHECK THAT ALL PINS ARE FULLY INSERTED IN THE SOCKET. IF OK, REPLACE PROM, CLEAR MEMORY, AND RECHECK. IF CODE 51 REAPPEARS, REPLACE ECM.

disconnecting a battery cable,pulling the ecm fuse, or unplugging the ecm will all clear the codes.
