Your first step is to see if the pump is capable of running.
Connect a jumper wire between the green connector and the positive post on the battery. That jumper will bypass all the fuses, relays and computers and supply 12 volts directly to the pump. That should make the pump run as long as the jumper is connected. You might have to remove the gas cap and put your ear up to the filler hole to hear the pump run. It's not very loud. And don't confuse the sound of the brake pump running for the sound of the fuel pump.
If you have a gauge (tester) to check fuel pressure you should have it connected to the fuel rail so you can read how much pressure the pump is putting out.
If the pump doesn't run with the jumper wire connected, try banging on the bottom of the tank with your hand while the jumper is still hooked up. Sometimes that will cause the pump to start running if the car hasn't been started for a long time. I've had that happen before.
If you do all this and the pump runs, we can move on to doing more tests to determine your problem. Don't worry about all that other stuff until you get the engine running.
