02 sl sudenly won't start

kevsink · 03-03-2008, 05:20 AM

Greetings....
Went out to start my 02 Saturn SL DOHC and it sort of burped and will not start up. Turns over freely and every once in a while, it sounds like it will fire but doesn't. Fuel pump turns on and I pumped the gas pedal a few times and I smell gas. Replaced the timing belt, gears @ 20k miles back. Car has @94 k miles on it. No warning with this issue....has been running great. Please advise if someone has a solution. This is my first time using a forum....looking forward to it!

Sounds like the engine is flooded. Try this. Key on engine off, push the gas pedal all the way to the flood. Then try starting it. It may take a bit to get it going depending on how much gas there is in the cylinders.

Timing Chain

Now to the problem at hand.

Check for spark following this video:
YouTube - Saturn Crankshaft Position Sensor(car not starting)

If there is no spark, the Crankshaft Positon Sensor needs to be replaced.

When the CPS is having issues it is either working or not working. There is no in between. Sometimes wigling of the wires for it may be all it needs, however Im guessing yours went bad.

Also, as Ssicarman stated, make sure you clear the cylinders of raw gas.
