Re: 99` saturn won`t start. I checked the fuel pump, it...
Have you checked if your getting spark. You can do this by removing a plug and having someone hit the key for you. watch the spark plug don't touch it or you will get zapped. If you see a strong spark you should be good. Do this for all plugs. Alternatively you can try the crank position sensor this should be mounted between the intake manifold and the starter. Follow the wires to the location and unscrew the sensor.
If that is not the problem and your getting spark and gas to the cylinders. Let me know
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

3 things keep a motor from starting.1. NO SPARK, 2. NO FUEL,. 3 ENGINE DAMAGE. I SUSPECT IT IS THE IGN MODULE WHICH IS INSIDE THE DISTRIBUTER. cHECK TO SEE IF IT HAS SPARK.. iF IT DOES THE IGN MODULE IS NOT THE PROBLEM. iF IT DOES HAVE SPARK CHECK TO SEE IF IT IS PUMPING FUEL.. DO THIS BY SQUIRTING A LITTLE FUEL INTO THE INTAKE MANIFOLD THROUGH THE INTAKE AIR HOSE RIGHT BEFORE IT CONNECTS WITH THE INTAKE MANIFOLD. .. iF THE MOTOR FIRES AND TRYS TO RUN YOU KNOW FUEL IS THE PROBLEM. IN WHICH CASE IT COULD BE A CLOGGED FUEL FILTER OR A INOPERTIVE FUEL PUMP. iF IT HAS FUEL AND SPARK LOOK FOR A BROKEN OR STRIPPED CAM TIMING BELT. NOT TURNING THE CAM OR CAMS.
if the timing chain is broken it will sound different like there is no compression also this is an interference engine i think meaning the valves will hit the pistons if the timing is not correct,like in a broken chain or belt.you should check to see if you have spark at the plugs and if the motor is getting fuel.if not then each system will have to be checked out depending which is not working.
Possible you must have the car checked for the basic fuel/ignition system. You will need to check on the fuel, the fuel filter, the fuel pump. Check the calibration of the pump . Also check the spark intensity , check the plugs the HT coils and the trigger voltages. The ignition timing also must be checked to confirm that the firing is correct. Finally the engine must crank well so that there is enough voltage to the ignition system. Hope there are no errors codes that come up when the ignition is turned.
Did you check to see if you have fuel pressure to your fuel injectors??? You probably have spark, just no fuel from your fuel injectors. Check that and go through the trouble shotting your fuel system, common for the fuel pump on saturns to wear out and having weak fuel pressure. Try spraying starter fluid though the air intake and see if the engine will start, if it does. Then you have fuel pressure issues.
Good luck and thank you for using Fixya
If it turns over but won't run, I would check to make sure you're getting fuel and spark. Pull a plug after turning the engine over a few times and if it smells like gas then you're getting fuel, if not then that's your problem. If you're getting fuel, you may not be getting spark. Hold the plug against the engine block and have someone turn the engine over a couple times. You should be able to see spark, but if not then there's your problem. Good luck!
most likely the feul pump. test the feul pressure with a gauge. look of ther little metal feul line on the intale manifold. tst pressure. have freind listen at the rear of the truck for the pump prime. key on only. then start the truck, friend should hear pump running. could also need a timming chain but pump is more tlikely
MAKE SURE FUEL TANK NOT EMPTY.LISTEN FOR FUEL PUMP OPERATION WHEN YOU TURN ON IGNITION KEY.IF NOT CHECK FUSE AND RELAY.IF FUEL PUMP RUNNING CHECK FUEL INJECTORS FUSES IF ALL IS WELL..SCAN IT TO CHECK FOR PCM PROBLEMS OR INJECTORS PROBLEMS.
you have spark and fuel pump primes when u turn the key / the timing chain has proper deflect but did it slip .sounds like the timing is off it may have spark but if timing has gone out it wont start either make sure it's in time next..
