i had a code 27 a couple yrs back. it was the injector wires. For some reason they became very hot and the plastic wire housing began melting the wires together. You will have to inspect the wires along the rail for any melted plastic. separate if necessary and 're-house' each individual wire. i used electrical tape. never had the prob since. Then again can just be a cut wire. Atart looking at the wires in the black 'box along the fuel rail
