Nissan Repair: 1995 nissan quest minivan, fuse panel, nissan quest

Question
There is no power going to the fuel pump. Replaced fuel relay under hood and checked fuses inside in the fuse panel. The van ran great. then after parked failed to start.


Answer
Jeanie,

The fuel pump circuit is pretty basic on a Nissan and if the pump is good and the relay is new and the fuse is good then you have a bad connection at the fuel pump as in corroded or loose.  Or, the ECM could be intermittently loosing contact and not grounding the relay for the pump when you turn the key on.  Or there is a break in the wiring between the ECM and the relay or between the relay and the pump.  Someone is going to need to get a test light and probe the circuit to see which of the above is happening.
