Code 51 prom error

[mr.La Rue]

Its finally running
I put 200 miles or so hopeing 51 would go away but no luck.
How to determine if it's the PROM OR COMPUTER

Did you try to take the chip out and clean contacts on chip and ecm. Reinstall and give it time to reboot? Don't forget to disconnect ecm power connector near battery or battery first.

If the ECM is burned, throw it in the trash.
A bad chip can not burn an ECM.
What "I" would do, is find someone local and swap ECM's.
