Bad fuel pump?

At the moment my car will not start. Im getting spark im just not getting any fuel. My question is how do you know for sure a fuel pump is shot?? Is there some relay or fuse that would shut the fuel pump down?

yes there is a relay I would check before getting a pump. It by your left foot on the drivers side. Remove the trim piece that runs along the door and it should be near the hood release. Its there on T/A's so it should be there on your Z. I hope this helps.

Jus checked it and i can hear the realy but i cant hear the fuel pump. When i turn the key the relay goes off about 2 seconds later,but no sound from the pump itself. Any other ideas before I drop 200 for a new pump?

If you can feel the relay energizing then go to the plug that is behind the back seats. I dont remember what pins but you can check for power there. You can see this plug from under the car also. That is where the harness goes from inside the car to the tank.

Sometimes a pump will up and die, other times it dies slowly and just loses more and more pressure over time.

There is a "fuel pump prime connector" near the PCM that allows you to energize the fuel pump for testing, circuit checking. Go to Shoebox's website... he has a picture showing the connector location.
