Hi Amedee, yes go ahead

If you jumper the dark green/black wire to the dark green/white wire at the fuel pump relay, the fuel pump should run.

If you want to ohm it out, it should read between 60 to 80 ohms.

I only find a green / black wire , a black wire , a yellow and red wire and two red / blue wires together , at the fuel pump relay

May I get your VIN please?

VIN 1J4GX48S51C634647

Thank you. That's better.

Jumper the violet/white wire to the dark green/black wire and the fuel pump should run.

You are right Amedee, I hear a click when I jump the indicated wires but no fuel comes out of the filter

Have you checked power and ground back at the fuel pump?

If so, does the fuel pump run?

Are you sure there is fuel in the tank?

Maybe the fuel pump is faulty.

I hear a click but dont hear the pump running

If the power and ground are good going to the fuel pump, the fuel pump is faulty and will need to be replaced.
