is the chip installed the correct way round?
are there any dry solder joints between the pcb and the eprom socket?
are all the legs of the chip in the socket?
do you have another ecu you can reconnect to the harness to check?

90% of the problems are usually a dry solder joint, which even just one will stuff things up.
