Question about Cars & Trucks
The engine computer powers the pump relay to turn it on, and then it gets power from a 20amp fuse marked ECM B in the box near the battery.
Are you getting power to the relay ?

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

Injectors or Carb? is there fuel presurt to the line near the engine and what is the presure.
The mechanoc was it a shop or buddy at home? Can you hear the fuel pump run when the key is turned on?

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump
