Saturn SC2 Hot Start Problem

I have a "new" Saturn. It's a 1999 SC2, same 1.9 Liter engine as the others. Problem is that it start fine when cold. After driving for 10 minutes or so, I turn the engine off at the store. Walk out after 2-3 minutes and turn key. NO START. the starter doesn't turn over. Doesn't even click the solenoid. I wait another 5-10 minutes and it starts right up. No problem. I changed the temperature sensor on the block with a new one. No help. Any ideas? Car runs great, other than this "Hot Start" problem. By the way. NO check engine light. NO battery low or charge light. Once it sits for a few minutes, turning the ignition off, then on - it starts like normal. Go figure. kim My saturn will not start when it is hot either. I can turn the key and it will click but nothing else. I can let it set for an hour or so and then it will start fine. I took the starter off and had both it and the sylionid tested and found nothing. I can push start it and it will fire right up. I do how ever hear a series of clicks kind of up under the dash when this is happing. I thought once it was the security system, but I cant seem to tell. It finally got to where it wont start at all unless I push statr it, hot or cold. I cant even jump it seems kind of electrical to me.

    I have this exact same problem. We replaced the started and this did not fix the problem. We also had the security system reset and this is still an issue.

My 1997 SC1 would start fully charged after about 5 minutes of cooling off (same as my Busa). If the vehicle draws lots of bettery energy when the ignition switch is turned (the headlights dim as if the battery was week) and all you her is a "tlock" then more than likely the starter solenoid is sticking when the engine gets hot. Age, as well as wear and tear in the vehicle, would cause for the stater, and the starter solenoid, to weaken. When the engine is cool it will start as if the starter was new, but after driving the car for about 10 minutes the problem starts. The engine running hotter than normal (ie.cooling system problems, diferent muffler system, low oil level), no necesary due to overheating, will add to the problem. My solution was a new stater ($115) and a starter heat wrap ($20), and I never had that problem again :-)

It sounds as if the crank position sensor is bad.When the engine heats up,it cases the sensor not to work.After the sensor cools it will work again.

How do i know if my 1999 saturn is a SL OR A SC SC OR S1 SO ON


The SL is the small 4 door
The SC is the 2 door Sport Coupe
The numbers refer to the engine. The all have a 1.9 liter. "1" is a Single Over Head Cam, 8th VIN will be an "8". "2" is the Dual Over Head Cam, 8th VIN will be a "7"

So a Saturn SL2 with be a 4 door with a DOHC 1.9 liter. SL1 will be a 4 door with a SOHC 1.9 liter. SC2 will be a 2 door with a 1.9 liter DOHC. SC1 will be a 2 door with a 1.9 liter SOHC.

SC2 car cranks and starts sometimes.put new plugs and wires and noticed oil on the 3 and 4 plug. Car once started with some starting flluid runs fine. and will restart. weather is getting cooler 20 degrees...


A common problem with the 90's engines was the ECTS (electronic coolant temperature sensor) going bad. Seems when attempting to start the car, the computer in the car will only allow enough gas it thinks is needed to start. When a car is cold, the computer gives more gas initially, until the engine warms up, then gives less gas. When starting a warm engine, less gas is needed.

If the sensor goes bad, it always tells the computer that the engine is hot. The computer give less gas to a cold engine, and sometimes it will start, sometimes not. Its a pretty cheap part, and a do it yourself one, just research it a bit on line...good luck

Interminently Losing Power 97 Saturn SC2


Hmmm, as to on-again, off-again engine power, it may be the electrical connector that runs from the electronic control unit. Read this diagnostic article, as it seems similar to your situation:

You might also want to read up on engine overheating since you say you seem to have that:

97 saturn sc2


I had the same problem with a 97 sc2. The fix for my car was the temp sensor that controls the extra fuel when engine is cold it didn't sense that the engine was warmed up and added extra fuel flooding the engine.
