So, yesterday morning the Pathy would not start. She cranked fine but would not start. She ran fine on Sunday when I made a 400 mile round-trip to visit family in Delaware. I'm don't know how to test for spark and fuel so I didn't mess with that.
Based the discussions here and elsewhere, I figured it was the IPDM. I had the Pathy towed to the local Nissan dealer ($110 ouch!). They diagnosed the problem to be a bad fuel pump and the initial estimate was around $850 -- bigger ouch.
My Pathy has 84,000 miles. I'm not surprised that the pump failed especially since it's been out of the tank for 2 fuel level sending unit replacements. That said, I wanted to see whether others are having fuel pump failures.
Thankfully, my Pathy is subject to the fuel level sending unit recall and I had not taken it in yet. When the second sending unit failed, I ordered the parts and ended up having it installed at a friend's shop. The third unit was working fine so I planned to until/if it failed to go for the recall.
The dealer confirmed my Pathy was subject to the recall. After checking with the service manager, the labor to replace the fuel pump was eliminated which reduced my total cost to $373.78 -- $355.98 for the complete pump and $17.80 for tax. The pump price (Nissan P/N 17040-ZZ00A) is basically Nissan list price. I wasn't charged for diagnostic so I'm OK with paying retail even though I could order the pump of the Internet for 1/3 less.
