If it is running ragged and eventually stops, it is because the engine idle is too high. It has an idle solonoid that controls the idle speed and sometimes you need to take it out of the throtle body and clean it, If it just idles smoothly as if you didn't turn the key off, it is probably the ignition switch which is on the steering column under the dash. Not where you insert the key. that is simply the lock mechanism.
The alternator is bad. The engine is running off of the battery and when you take the cable off it has no electrical power. If the alternator was working, the car would keep running. Be advised, doing this can damage a healthy alternator. This is not a good way to test the system.
Fuel filter may be clogging up enough to not provide enough gasoline to keep the engine running, but will accumulate enough gasoline in it to re-start the vehicle.
No. The air conditioner is driven by the engine crankshaft, so it will not turn if the engine is not running. Just so you know, you are wasting a lot of gas by driving around with your A/C engaged all the time.
Make sure the pump keeps running when you start the engine. The pump will shut off after a few seconds if you just turn on the key then don't start the engine. That's normal. But the computer is designed to detect that the engine is running and if so, keep the fuel pump running as well. If the computer somehow isn't detecting that the engine is running, you probably have a faulty sensor, connector or wire. Make certain that you check the wire! Sometimes the wire can be damaged and the fuel pump will not run. Good luck.
Most of the time rough running and stalling is due to vacuum leaks. There is more of a load on the engine when it is in gear, so that lends itself to stalling out. When I look for vacuum leaks, I have the engine idling (maybe you need a friend to keep it from stalling) and then spray carburetor cleaner around the various hoses & gaskets that could be leaking. Any increase in the idle speed would be an indicator that you have a leak in that area.
look at your belt with the engine running (keep your fingers out) the pully on a little arm that bounces is your tensioner.
It could keep the engine from running, but not the valves from moving.
I am not sure how much it would cost to rebuild the engine, but I just did an engine swap on my saturn. The engine cost $325 and it had 102,000 miles on it. Keep in mind that this price doesn't include the price for the oil/filter, coolant, sparkplugs/wires. All said and done my car was up and running like a new car for under $400.00. The hardest part of the whole thing was actually finding an engine for it.
It will keep running until the engine is destroyed if that is what you are asking.It will keep running until the engine is destroyed if that is what you are asking.
No. It will keep running until the engine is completely destroyed.No. It will keep running until the engine is completely destroyed.
Air conditioner or defroster on - normal should be running Vehicle low on coolant? Trying to keep engine in normal range Defective coolant sensor?
It is important to use the correct type of oil in a car to keep the engine running properly. For this particular car, it is recommended to use a 5w-30 oil.
Its not your engine. Its the fan running to cool the engine down. They all do it and nothing is wrong with your car.
( NO ) with the engine cool
more likely to be a faulty coolant sensor or the thermostat is faulty and staying open
Three things can keep an engine from running, a faulty ignition source, lack of fuel or insufficient compression. If all three are present in the proper percentage, an engine MUST operate. Your problem is to find out which of the three is missing, then you can solve the problem of how to repair the engine.
How well do you maintain it? The Saturn engine is well engineered and is capable of running several hundred thousand miles if you keep the fluids full and change the lubricant at the proper intervals using a high quality oil. Most machine shops will recommend full synthetic if you want an engine to last. But it's up to the owner.
