How to fix a problem with a 1995 Honda del sol, where the fuel pump only works sometimes?

The fuel pump has been replaced but only gets power sometimes. It's not the regulator and not the fuse. They have power going to the fuse but not to the fuel pump.

Check the wiring car shake alot and could shake the wiring.

You don't mention checking the fuel pump relay, known as the "main relay." It is one of the most common (probably *the* most common) Honda failures. See the source for more information and a test.

Hi it is going to need a new fuel pump soon this will be a thousand dollars or more along with the mechanic spending hours diagnosing other issues with a 20 year old car. I would suggest selling the car before it needs this pump.
