Customer Question

Replaced fuel pump and filter. Truck ran... I drove it home. This morning it won't start.
JA: Have you ever replaced the fuel pump, or is this the original?
Customer: Checked in line valve..appears to have no fuel to the injectors
JA: What is the model/year of your Nissan?
Customer: 1999 pathfinder
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I have replaced the pump. Replaced the filter. Drove 30 miles home. Truck ran awesome on the way home, now won't start. Tried to bleed any air out.
JA: Anything else you think the mechanic should know?
Customer: One of the fuel lines to the pump in the fuel tank isn't the correct hose. I replaced the lighter weight accordion style hose with regular 5/16 fuel line.

The accordion hose you replaced is installed using heat to shrink the line so it gets a tighter fit. If you replaced this hose with a regular rubber fuel hose, it is possible that the hose has come off of the nipple and the fuel is returning back in to the tank instead through the line and to the injectors. Can you hear the pump activate when you first turn the key to the run position?
