2001 Kia Sportage won't start. Driving the other day it died like it ran out of gas, like it has a few times. I added gas, it started, then died before I could drive off. I replaced the timing belt a year ago, just had new alternator installed. Points, plugs, coils etc were all just checked/replaced. My first thought was the fuel pump, but how do I know what to check?

I know that it will cost a little bit of money, but personally, I would take it to a shop and have them test the fuel pressure in 2 places if they can. First they should check as close to the fuel pump as possible (without taking out the tank to charge you for that too). If there is low pressure there, it's very likely that it's you fuel pump. If everything checks out there, they should be able to check the pressure at the fuel rail (most of them have a cap, like a valve stem). if there is low pressure there, most likely there is a clog in you fuel line (they are probably formed fit lines, so they may be pricey), but if everything still checks out, I would see if they could flush the rails/injectors, hopefully fixing the problem. If the problem still shows....... I hate to say it....... but it could probably your injectors, and they can be very expensive.
