2001 s10 4door 4wd fuel system

Have you listened by putting your ear to fuel filler if you can hear the fuel pump whirring as someone turns the ignition to accesory , if you can not hear the fuel pump motor for about 3-4 seconds whirring your fuel pumps stuffed

Can either be fuel filter is dirty or fuel pump is going and there may be a short or burnt wire on the fuel relay. they should all be located in the same area.

You have a fuse / relay box under your hood. My 2002 L100 special edition, 4 cylinder, is located near the battery. You have a relay and a fuse in series. A fuel pump operations check, section 4-3 of the Haynes Saturn L-series 2000 to 2004 manual, you can hear a soft whirring sound for 1 to 2 seconds when you turn the ignition to the ON position. I can confirm mine makes this sound when I do this. Good luck with the fix.

Note, I had a crack in my fuel pump, but I took it to an ex-Saturn dealer 4 or 5 years ago because I did not want to mess with it at the time. They had the part and fixed it in 4 hours, but it also cost me $1000 to replace the fuel pump and install a new fuel filter.

It may take 3-4 times cranking for a few seconds,
with a 5 second pause between to get fuel up to the engine. Also may have sucked up
some dirt/debris into the fuel pump after running it dry. May want to change fuel filter.
you can try to have someone bang on the bottom of the tank while someone else
cranks engine. Sometimes this will free up a stuck fuel pump. good-day!!

When you turn the ignition to on you should here the fuel pump run. If you aren't hearing it then it sure sounds like the pump. Assuming nothing has happened to the car to affect electrical connections. I don't think there is a fuse for the pump but worth checking also.

When you turn the key to the ON position, you should hear the whirring of the fuel pump working. If you don't hear anything it may be your fuel pump. It only lasts a few seconds but that sound is evidence that your fuel pump is delivering fuel. If it is good, then check your fuel filter.

does it get spark? you can purchase a fuel pressure gage and check the pressure yourself. Also turn on the ignition and then get back by the fuel pump and listen for it. if you can't hear it run then it needs to be replace.

vehicle needs serviced fuel filter blocked hope this helps?

if its petrol engine bang bottom of fuel tank while some one else cranks vehicle over if it starts good just pump jammed if it dont buzz to life and you cant hear fuel pump buzzing ceck for power to it if thats there replace pump. running out of fuel kills electric fuel pumps internally in petrol tanks.

if its diesel you must bleed fuel system taking extreme care if you un do lines some very high pressure

The cam or crank position sensors are notorious for failing, after they age and get heat in them the signal is no longer generated. Also make sure fuel lift pump is working properly, check all of the fuel filters and for fuel leaks of any kind including sucking air on the suction side of the lift pump. Good Luck!!
