Technican: Could you clarify what you mean by "by pulling it off in reverse the first"? You are on the right track trying to check for available voltage to the pump. One other thing to consider is the pump gets hot when you run out of gas. It may be shutting down. Sometimes a few hits to the fuel tank with a rubber mallet (don't use anything that can create sparks or damage the tank) will get the pump going again. Avoid running low on gas. The fuel in the tank actually cools the pump. When you are low on fuel damage to the pump can occur. Many aftermarket fuel pumps die the first time they are overheated.

Owner: how would we know if the fuel pump has burned up my husband has tried everthing been working on it for 2 days
Technican: First off he needs to verify there is spark to the spark plugs. If there is he needs to check fuel pressure. Or at the very least listen to see if the fuel pump is running (do this while the engine is cranking). If the fuel pump does not run and the car ran out of gas there is a good chance the pump is bad. To determine if the pump is bad check for available voltage to the pump with the engine cranking. If voltage is available to the pump and you don't have fuel pressure (or can't hear it run) the pump is bad. Once again only chase the fuel pump is there IS spark to the spark plugs."
