A friend of mine has a 2002 saturn t100. It was driving fine one day, he parked after coming home but when he went to get into it later it only turns over and wont start. I noticed there was no fuel reaching the rail and his fuel pump doesnt make that humming noise it usually does but all the fuses and relays are good ( i switched them around). do fuel pumps just go out like that on those cars. Vehicle has 100k plus miles.

The electric fuel pump can go out at any time without warning. I have had several go bad. The vehicle was running fine when parked, and then would not start. One instance was within 5 minutes (I had just stopped for a cup of coffee)
It is either the fuel pump (98%) or a problem witht he wiring to the fuel pump (2%) If there is power at the pump, and no fuel pressure, it is replacement pump time!

that is exactly how the engine acts when the Fuel pump is bad don't know why you changed the freeze plugs yet but you are describing a fuel related issue. Whats the mileage on the motor ? and year? make and model? fuel injection in front wheel drive has the fuel pump in the gas tank its always at the top and most of its life people never fill up the tank unless traveling to another state. Over time it runs hot for way too many hours because it is designed to be kept cool by being surrounded by fuel. Once you replace it start filling up the tank at halfway. This keeps the pump surrounded by gas more often than not.

No, fuel pumps do not go bad from one day to the next. They do, however, eventually succumb to wear and tear, and stop working. In most cases, the faint humming noise of a healthy fuel pump will grow louder over time. Close to the end of their life, they can develop a quite audible groan or rumble. However, they will keep on working till the end. Occasionally, one might notice a drop off in performance as a failing pump may provide uneven fuel pressure.
When the pump finally fails... well, that, is quite noticeable. The car becomes and instant paperweight.
Fuel pumps are governed by fuses like most other circuits in the car. Good idea to check your fuse panel first. I had a fuel pump/sending unit go bad resulting in endless blown fuses until the unit was replaced.

It seems that they do at the time it happens. also try checking the fuel filter and fuses. My daughter had a car that did that and after she replaced the fuel filter, pump and fuel line it turned out to be a fusible link in the wiring that fires the fuel pump. Good luck with it

OFTEN,IF THE FUEL PUMP IS THE PROBLEM,IF YOU GET UNDER THE CAR AND WACK ON THE TANK AS HARD AS POSSIBLE,THE PIMP WILL TAKE OFF AND START WORKING.
THIS IS NOT A REPAIR,JUST A DIAGNOSTIC PROCEDURE.EVEN IF THE FUEL PUMP STARTS WORKING AGAIN,YOU WILL NOT BE ABLE TO TRUST IT.

I had to replace the pump twice once...brand new one can be faulty.
You did good job in finding the problem.
Good luck!

They indeed can and often do die from one start cycle to the next with no warning whatsoever. Good diagnosis.

No, they go bad from one second to the next.
