SOURCE: 1999 Saturn SL2 DOHC Engine - Fuel pump not pumping fuel.

The Saturn Fuel pump relay and fuse is located undar the panes on the passenger side of the center console near the passengers left foot there are two relays there that look identical one is fuel pump relay. Just switch them around they are bot the same and see if the fuel pump runs now also the fuel pump fuse is in there i can't send diaagrams on fixya because their program will not let them go through if you need one email me at [email protected] Please give me a fixya rating if this information is helpful to you

Does your "security" light flash? If so that's your Body Control Module.

SOURCE: 2001 SATURN L-300 no fuel pressure, change fuel pump

if you have no fuel pressure check the fuse n the underhood fuse block even if its good its still most likely the fuel pump is bad the fuse rarely blows even when the pump is bad,,the 6 cylinder only produces fuel pressure when cranking the enigne

You can check in the trunk and remove the felt cover see if there is a round panel cover that you can remove to get to the tank. If your unlucky and have to remove the tank you will have to remove the tank. The cover may be under the spare tire so pull it out. It is not to difficult to do, if you drive it till the gas is almost out you can remove the two bolts that hold the tank in place. Use wd-40 to spray on the bolts and also spray the hinges on the oppitse side of the straps. once the nuts are off drop the tank down. You will need to pull the screws off the tank filling tube so it will come down as well. drop the tank down far enough for you to get to the fuel tank sending unit. it will have philips screws holding it in place. Mark two spots with a felt tip pin, (Sharpe) white is better and mark two holes so you can line the it back up for the holes and the hoses. disconnect the fuel line and return line disconnect the battery of the car for safety then pull the wires off it can be a plug or it may have nuts on them. When you remove the nuts or screws out pull the pump out and you will have to angle the pump to get the float out. I recommend that you replace the pump and the sock on the end of the pump. Do not buy after market buy factory replacement only you only want to do this once. mark the new pump holes on the pump using the old pump as an example, will save a lot of time to get it to fit in and match and the lines will line up, tighten all screws up put the lines back on and the clamps and reinstall the tank in place. yo can use your knees to hold it in place till you get the clamps lined up and started. Screw the nuts down till tight and your set to go just hook up the battery again and your set to go.
SIde Note, Never let your car get below 1/4 of tank of fuel, the reason is gas is the coolant for the pump if it goes lower than that the pump will heat up and will burn out. Many people don't know this so I thought I would add this to your knowledge

Mine was doing same, but also revving up weird. I replaced the Crankshaft position sensor and it didnt work. Today I changed the Engine coolant temp sensor and it fixed my problem. Hope this helps!!
