Common symptoms of electric fuel pump failure include a car that simply dies on the road, and a car that may stop and start back up intermittently. Find out how to diagnose a failed fuel pump with help from an ASE-certified technician in this free video on electric fuel pump failure.
Hello, my name is Chuck Orlandi with Miami Shores Auto Repair here in Miami Shores, Florida. The symptoms that you would have if you had an electric fuel pump failure, normally, you'd lose power. The car would be driving along and it'll just quit. Sometimes, you'll have intermittent problems where the fuel pump will stop pumping. You may shut the car off, start it back up, it might start. That's something that's...you know, it's harder...hard to know which way it's going to fail, but nevertheless, either way, it's going to have to be something that's taken care of. When we get those cars in here, usually, they come on a tow truck. The first thing we do is check to see if we have fuel or...and/or spark at the spark plugs. That's when a car cranks and doesn't start, that's what we'll do. Then they...most cars now have a fuel line adapter where you can hook up a fuel pressure gauge, put it on there and crank it. If nothing happens, we know we've got a problem in the fuel pump. Typically, most fuel pumps today are inside the gas tank. You'll have to drop the fuel tank out of the car, drain... First, you drain all the fuel, drop the tank, pull the fuel pump out, and then we replace the fuel pump and the filter. Those jobs can get quite expensive, depending on the parts, but most of the times, they can get over 500 dollars real easy. Most of the times, up in the 800 dollar range to change a fuel pump. Then, again, it's not an easy job to do, and it is quite a common problem. The main way to stop the fuel pump failure, if you want to try to prevent it is to replace the inline fuel filter on a regular basis.
