It’s coolant related. Water passing through the heater core. May need to consult a bleed procedure on line for that engine. Lots of manufacturers require the cap on and a plug removed on the engine. Of course there can’t be any leaks.
Air in system....park on a slight incline...open radiator cap...start car with heat on.
Check your evaporator drain hose. Could be water in your hvac box. Make sure water hits ground with a.c. running
You have to open the bleed ports . there are several located by the engines thermostate housing and near intake hoses. It will allow the air to escape .

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
SOURCE: Car won't start!!
AmyLynn001, 1st thing, let the car sit for a couple hours (because u smell gas, it's definitely flooded). Turn the key to start (do NOT touch the gas pedal!! Cars are designed now to start w/out touching the gas pedal. If u do, u will flood it, and make it even more difficult to start) When u turn the key, only hold it to turn the engine over for no more than 10 seconds. If after the 10 seconds it doesn't start, turn key off, wait about 10 seconds, repeat. (this is to reduce wear and tear on the starter, and to not run the battery down real quick). It sounds like several problems coming together caused this. U state that the car needs a tune up, it's likely the overheating, need of a tune up (car not performing to optimum efficiency) and pushing on the gas pedal, resulting in flooding, all came together to create this no start condition. Eliminate any one (preferably all!) and u should be able to start the car. So, hopefully just letting it sit and not touching the gas pedal while attempting to start will be enough to get u back on the road, then get that tune up soon. Let me know how u make out.

SOURCE: 2003 Saturn, DOHC V6, burning smell in interior after car warms.
if the smell only comes on when the heater is on try pulling the blower motor mice like to build nests in the blower motor housing.
