My GF owns a 94 mustang 3.8 and the engine will turn over but won't fire. She turned the engine off and left it off for 3 hours. When she came back the engine wouldn't start. We thought the problem was a fuel pump since the pump wasn't making noise when we turned the key. We replaced the fuel pump and the new fuel pump didn't help. I assume there's no spark because the pump still isn't pumping fuel through the filter. Anybody have any idea? I haven't checked the spark plugs, but i took off the wires and there weren't any burns.

First check fuel pressure and see what it is. If you are turning on the key wanting to hear the fuel pump listen close because it will only run for a few seconds to prime and shut off. Also check for spark and make sure you dont have any. After these are known then we can help you better.
