If there are problems with the fuel pump there are things that can be done before going out to look at fuel pumps for sale. There are two kinds of tests that can be run on a fuel pump; the fuel pressure test and the electrical test. Here is a look at both.
The Fuel Pressure Test
- Start by checking the filter, this is often the real problem. You definitely do not to go looking at fuel pumps for sale if your problem is with the fuel filters. These can often get clogged with a number of things (debris, sludge).
- Buy a new fuel pressure gauge. These can be found at any auto parts store. They generally range anywhere from $20 to $30 a pop.

If that is the case, you should take the vehicle in to be checked by a professional.
