Don't know if this will help but I had the same code on my setup on initial trying to start engine.it was the chip not making contact.at key on the check engine light would come on then off then flash quickly. Once the chip made proper contact on all the pins it worked.I also had the same problem after soldering in a chip socket.I checked continuity to each pin with dvm and found one not making contact. U might try wiggling the chip and see if it starts.hth
