I got very lucky (for the repair, not the fact it was damaged), we had put our daughter's 2004 Impala out by the road with a FOR SALE sign on it. A week later I wanted to move it to mow. No start. I FINALLY found the varmints chewed a sub harness from the trunk floor to the fuel tank. There was an access panel in the trunk for replacing the intank fuel pump. I went to the salvage yard, found an Impala someone else had pulled the fuel pump from and left the sub harness. Easy unplug and take it home. I paid $7 for it, plugged it in our Impala and it started right up!
