I changed my fuel pump and my fuel relay and there still wasn't any gas passing to the motor. May you please help me?

Use a gage and check fuel pressure. Use a noid lite and check for injector pulse, engine cranking. Let us know what you find.

Without something to point us in the right direction, it's hard to know which way to go? National brand autostores used to loan out a fuel pressure gage. They also sell noid lites, I don't know if you can borrow one?

I can't help but notice you didn't start by replacing the fuel filter. This is the most overlooked mait. Item there is and can cause your problem. Sounds like you started replacing the expensive stuff first. I would suspect that yours has never been changed, especially if you bought the vehicle used. The recommended interval is 15,000 miles but I've replace factory fuel filters on 100,000 mile plus vehicles. I guess it just depends on how dirty the fuel you happen to get is. Anyway, I would replace this inexpensive little item before going any further. It's on the frame rail under the vehicle I think just at the rear of the driver's door.

Please disregard any posts to this thread prior to this one. My computer browser was left open to this topic and teenagers thought it would be a good idea to give out some advice under my name. I apologize for any inconvenience this may have caused and have taken steps to prevent it in the future.
