Nissan Pintara 1986 no fuel pump operation could not find power & earth at fuel pump Could it be fuel pump relay ?

SOURCE: 1986 Accord - fuel pump relay problem - HELP!

Just replace a fuel pump myself and had the same problem. I found that the wires going to the pump inside the tank where grounded out. While setting the pump in the tank I got the wires pinched between ths tank and the cover. Hope this helps.

Personally I wouldnt bother tracing the wire as it is probably not worth your time, and just run a constant 12v from the battery to the relay on like 10ga wire. There is probably a short somewhere in the system which can be a real headache to find.

Also it may sound dumb, but check your fuses, and the fusible links under the hood. Chances are that they are all fine though, especially if you have dash lights.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

I've been bitten by this twice! The culprit both times was the connector plug under the van infront of the fuel tank. the second time the connector pin and socket came loose inside the plug itself,( workes for a while then dosen't). Make sure there is good secure contact made in all sockets in this plug, and the pins are held where they need to be inside the plug itself.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge.
