So, my Pathfinder killed another fuel pump -- third fuel pump in 5 weeks. Pathy wouldn't start Monday evening. Checked obvious and added two gallons of gas just in case the 1/8 tank reading on fuel gauge was off due to pump replacements. Still no joy. Hoping pump will "reset itself" if I let it sit a while.
Rode into town with kids to have dinner with wife and kids. Picked up a can of started fluid after dinner and headed home. She still wouldn't start (only 3-4 hours later). She did start with brief sprays of starter fluid so it's definitely fuel supply problem. She still would not start the next morning so I had her towed back to the Nissan dealer that did the other two pumps. I also call 800-NISSAN-1 to get a case opened.
Initially, there was good power and ground at the pump but apparently that changed the next morning. Further investigation found a bad ground connection on the "terminal side of the fuel pump power connector." I understood that to be where the wire attaches to the connector assembly and not where the connector mates to the pump. The terminal and/or wire were discolored. The bad ground was causing voltage variances which caused the motor to burn up.
They repaired the connector and replaced the fuel pump. There was no cost to me to diagnose and the connector problem. Unfortunately, I did have to pay to have the Pathfinder towed to the dealer since she is well out of warranty.
