the temperature sensor often causes symptoms such as this. it incorrectly tells the computer that the engine is cold and needs a rich mixture which results in black smoke and hard starts. another cause for such a condition is fuel injectors that are dribbling rather than atomizing fuel spray.

Will not start after it run for a while

usually after a car runs for a while and you shut it off and it wont start it is the fuel pump getting hot, you can easily check it the next time it doesnt start take off the gas cap and have someone to turn on the igniton key to the on position and listen at the gas nozzle for a humming sound if you hear nothing then your fuel pump is getting hot and shuttind down. hope this helped

Flooding hard to start

If it is flooding you have to open the throttle and it will start easier. check the fuel regulator it may be bad. also you may want to replace the spark plugs as they will get fouled out

I race a 1994 saturn on a dirt track. My car runs

Is it a stock engine?

If so check your ECTS water temperature SENSOR not sender, it's located on the right side of the block towards the bottom drivers side engine compartment.

Change the harness connector to it as well it usually goes bad due to corrosion, the original ects sensor was plastic which cracks, the replacement is 8 bucks at auto zone and is brass.

If this goes bad your engine will run rich, waste a lot of fuel and foul the plugs causing the engine to cut out.

If this is fine then check your ignition system for failures due to vibration.

97 Saturn sl2. Won't start after it gets warm. If you drive it for 15-20 minutes and try to restart it will not engage the starter. Wait a couple hours and it will start fine

It is your engine coolant temp sensor (ECTS). 99.9%. the saturn made them with a plastic tip, so they crack over time. A replacement should be about 15 bucks and not too hard to replace. You'll notice your engine temp gauge not working (always cold).

I don't know much about cars, but here's what happens. When your car is cold, the fuel runs rich. Your broken sensor is always reading that the engine is cold, but when it is warm, it runs too rich and floods your engine, not allowing it to start. When your engine is actually cold, everything is fine.

QUESTION: I have a 97 Saturn SL 2 179,000 miles

You need to change your ECTS and it's connector if it has gunk and corrosion in it. Change the ECTS to the brass tipped one and get rid of the plastic tipped one in the car.

Also change your Thermostat which is located inside the lower radiator hose on the engine block. Sounds like your car is running itself rich because it thinks it is cold and flooding itself (hence the full throttle which is a "clear flood mode" and shuts off the injectors while starting).

1994 saturn sc won't start after driving couple of miles

the common problem on these cars is a bad coolant temp sensor when they start going bad they will read a cooler temperature for the computer than the actual temp some times it is a big difference.and the colder it reads the more gas will be supplied this will flood the car and you will smell gas.the part is cheap.about ten dollars
