Fuel Pump Died - Need Help Please

[4door_Sleeper]

My fuel pump died in the wife’s skyline last night, had to get towed home.

I have taken the pump out and applied power to it (1xpower, 1xearth) and it wont turn over.

Tried the same on a old pump I took out of my car (to upgrade to a better pump) but it refused to turn over either (could have just seized after sitting on the shelf for 12 months)

Should the pump turn over when power is applied (direct from the battery) or is their a safety mechanism that will stop it from turning unless its emersed in fuel?

Thanks

Try this.

- Put back the old fuel pump

- hook it up and screw on the cover

- hook up the electrical connection for the pump

- get a cheap "malet hammer" - the rubber type, and knock quite hard on the top cover of the fuel pump while your wife keep cranking the car.

- If it starts, fuel pump faulty. If it don't start, have it check by a mechanic.

I tried the hit it bit prior to taking it out, it definitely a fuel pump problem.

Another useful test was putting some petrol in the plenum (through a vacuum line attachment) and turned it over. It ran for about 15 seconds then died (thus not a spark problem)

Checked power at the pump (tested OK)

Hit the tank with a mallet – still no luck so I had it towed home and removed the pump.

I think the direct connection of power to the pump (with no result) proves this is the problem.

I’ll get another pump during the week.

replace the fuel pump with a new one, install it the same way as how u took the old one out, to test the new fuel pump to make sure it works undo the fuel hose in the engine bay and put it in an empty bottle, turn the ignition on a few times and listn for the pumps buzzing noise, if fuel comes out the lines to the bottle its working. connect the line again and try start the car, if it still dont start u have other problems
