    What do you mean "will not idle?" Do you mean it shuts down after starting? If it stays on it is idling high? At what RPMS?

I have one, so here you go-check compression, if it's good (should be 190+ all cylinders), clean the throttle body (remove it, not hard to do, 4 bolts) and clean it both sides, and remove the idle air controller and the throttle position sensor and clean them-throw on a set of plug wires, a set of plugs NGK's, copper)-after that change the Engine coolant temperature sensor (8 bucks), and change the oil-for another $100, you'll have a great little car, good on gas, for years but watch the oil level...they do burn oil.

99 saturn loud revving sound in engine

Start the car and use a spray bottle to spray a bunch of water mist around the top back of the engine where the intake meets the head. If it starts to die you have an intake manifold leak. It\'s kind of a pain to change, but not really technical. Also, clean your throttle body and clean the idle air controller (IAC). Alos consider replacing the Throttle position sensor (TPS). Both are located on the back of the throttle body.

I got a 99 saturn i dont know if its the battery or a starter starts up fine drive it when when u trun the key off and then try to start it then there is nothin lights work and radio are fine what do i do?

I think you have a bad starter my 99 SL 2 was doing the same thing.What i did to be sure was one time when the car would not start I put the car on jack stands got under it had someone sit in the car turn the key like you are trying to start the car then you hit the starter with something to jar it if the car starts you know that it was the starter.worked for me.
Good luck.

Fuel pump replacement

it is inside the gas tank, like about everything made since 1991. you have to remove the tank, kind of a messy and complicated task, plus all the mounting hardware is rusted tight and will break off in your hands. get a repair manual on eBay for about 5 bucks, read it and think about it before you start tearing things out.

the car is worth about 500 bucks, a new pump is about half that much. you might want to think about buying a 99 saturn with lower mileage instead of fixing that one. i had 4 of them and in my humble opinion the best saturn ever was a 99 stick wagon. i am sure the sedan was just as good and there are many out there.

Have a 99 Saturn, rough idles, stalls, high RPMs when first started, then idles to rough idle, what is the first thing I check?

Sounds like the EGR is hanging open causing an internal vacuum leak.... Check all vacuum lines first for cracks / splits and then pull the EGR and make sure the pintle is not stuck open with a chunk of carbon.

My car ran fine but all at once it started missing and the ioling would go up and down...then when i went to start it the next day it would turn over but wont start 99 saturn station wagon

It seems like a bad idle Air control Valve or an Idle position sensor. The best way is to get a trouble code for free at most autoparts stores and they will tell you what might be wrong.

Will not start after it stalls untill about 5-10 minutes

spray carb cleaner on the intake manifold near cylinder 1... common problem is the intake manifold gasket leaks vacuum causing a misfire...the not starting could be due to a faulty crank sensor
