My car will start but dies immediately unless I keep my foot on the gas pedal. The lights, radio, and battery sounds fine and all turn on and I just replaced the battery so it's not that. I got a diagnosis for it and they said the throttle needed to be replaced and the fuel system needs cleaned. Is this accurate? How much should that cost? The estimate was $400, which seemed like a lot
Get the fault codes read somewhere else
first have the ecm reset using a scan tool as replacing the battery can corrupt the program

MY 2002 SATURN VUE 3.0 6CYL KEEP ON STALLING ON ME I DON'T KNOW WHAT TO DO IF YOU HAD THIS PROBLEM PLEASE LET ME KNOW WHAT THE PROBLEM WAS PLEASE
SOURCE: When I start the car, it dies when I press the accelerator
this sounds like a mass air flow sensor problem. they make a cleaner for the m.a.f. try that first and see if your problem goes away. if not you might have to replace the m.a.f.
SOURCE: 99 saturn will carnk but won't start
try cranking engine while holding gas pedal to the floor, this turns off the fuel injectors to clear excess fuel from cyls. eng my just be flooded. may need to crank for a long time. if engine starts do not let off gas until you are sure eng will run on its own.
SOURCE: 98 saturn sl1 won't start
I have a 98 Saturn SL1 from time to time it would not start, it wouldn't even try. I knew the battery was good. It turned out to be the cranshaft position sensor.

Sounds like you are pretty knowledgeable with the maintenance. With that said do you know if the Engine Coolant Temperature Sensor (ECTS) has been replaced? I'd put that at the TOP of the list of parts to replace next. If it hasn't been replaced it is the cause of a lot of problems.
The factory one is plastic and cracks. When it cracks it sends the PCM a signal that the engine is -40F below zero. The PCM will compensate by dumping A LOT of fuel into the engine to try and warm it up. It will cause all kinds of starting and idling problems.
Autozone or the dealer sells the better brass tipped one. The ECTS is located just under and behind the upper radiator hose. You'll need to remove the air intake tubing to see it or get to it. It has two wires going to it and goes into a connector. Squeeze the connector at the "ears" and it will come off. A 10MM DEEP well socket will take it out. Swap it quickly because some coolant will come out (a couple of ounces). Hand tighten it and snug it with the socket (not too much because it will strip out). Connector back on (either direction it's non polar). Put the intake back on and enjoy better starting and idling.
Testimonial: "thank you very much. youve been most helpful and i will let you know how it works out for me as soon as i replace the ects"
