Asked by Jan 09, 2014 at 10:17 AM about the 1987 Nissan 300ZX 2 Dr GS

Question type: Maintenance & Repair

My 1987 300zx non-turbo will not
start. I put a brand new fuel pump on
it along with a fuel filter and fuel
pump relay. It will turn over fine but
will not start.

Are you sure it is fuel and not fire?


Yes. It will turn over fine but when you turn the key on the fuel pump doesn't kick on.

This may have a fuse too. It also probably has an inertia switch which is usually located in the trunk or at the right kick panel on passenger side at your foot. This trips if you are in an accident to shut off fuel. Also look under the rear seat at the harness for the pump.Sometimes the wires will corrode for the fuel pump at the harness plug in.

The inertia switch can trip itself if bad.Doesn't have to be in an accident.


I can't seem to find an inertia switch. And mine doesn't have a backseat. But I don't see any corroded wires.


Did you check fuses?


Yes all the fuses are fine.


You either have a broken wire/unplugged at fuel pump or the pump you installed was bad in the box new.


I did the same thing I put new fuel pump and did not work after too much work looking at fusses andchacking everything it did not work ..I was about to quit after all that I found the problem it was the green relay by the battery the my fuel pump start working awesome hope it helps
