Question about 2002 Chevrolet Blazer

What's the difference between fuel pump & replacement fuel pump

This past weekend I was driving home from work and my 2002 Blazer began to stall out (felt like someone pushed me real hard from behind then truck slowed down then like being pushed real hard again). Then all of sudden the car shut down on it's own while in motion. Fortunately I was able to pull over, a DOT truck came and he tried jump start the car thinking that was the problem but nothing worked - slowly I lost all power to anything electric (blinkers stopped working and lights dimed until they were completely off). The weird thing was that if I tried to start the truck it would crank but would not turn over. We replaced the battery thinking it was that but nothing happend except for getting all the electrical in the car to come back on. We ended up having the car towed to my home where it sits - a mechanic friend looked at the car and told me it was the fuel pump and have to get it replaced. In searching price points I came across different makes and models (like everything else in the auto part world) My question is what is the difference betweens a fuel pump and a replacement fuel pump? Do you believe the fuel pump the actual problem of my 2002 Blazer? Thank you for any advice you may have!

The fuel pump might have went bad because of the low voltage when the alternator quit check the fuel pressure and make sure your gettin good spark if you do need a fuel pump a replacement pump will be the same thing you have you will just have to tell them your year make and model.

I dont think you have a fuel pump problem, It sounds to me like you have an alternator problem. You see when your alternator quits working the car will run on your battery juice untill it is out of juice and all electrical will go out when you put a new battery on it it will start working again untill the new battery is out of juice or untill the alternator is replaced. If the vehicle wont run then the fuel pump might have went bad too. I hope that helps you out.

You could have gotten bad gas in your tank. Did you try dry gas at all? Also, bad gas can leave alot of sediment at the bottom of your tank, waiting for the right movement to get moving into your system. A new filter would only get quickly clogged again. I had this happen- got gas from a station after a flood- fuel tank had to be dropped and cleaned out.

check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems
