2002 Saturn SL1 engine turns just fine but won't start

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.

Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

A quick check, is turn your headlights on, try to start, if lights dim almost to off, bad battery, if they don't dim, it's a bad starter assembly.

you most likely have a plugged catalytic converter and a stuck open egr valve. Your car has two one is a digital electric and the other is mechanical, this is a common problem for that car. The digital is hard to find on the engine and hard to get at but if you want the procedure I can tell you how to fix it by removing and cleaning.

replace it before you end up spending more than you want to $$$$,regee

You headlight switch could be at fault.

it is possible that its set to do that,its called a afterblow option,so it turns off and on byitself as a way of keeping the evap core dry,,may be normal

Have the alternator and battery checked. The battery may not be holding a charge. The alternator may not be charging the battery,it should put out between 14 and 15 volts,any less the alternator is bad.

What Model is it they didn't make an SL1 in 2003?? S-Series only till 2002.Update your year & model & I will try to help!!
