Your car does indeed have a computer in it, everything built after 1981 had computer conttrolled emission systems. Test the fuel pressure, should be at least 17 psi at idle. Have you changed the fuel filter? A blocked fuel filter could cause this problem.

Car was running then just quit and won't start. 3/4 tank of gas. will turn over rapidly


Really sounds like a broken timing belt. Such a problem "sounds like" you hooked 2 car batteries to the starter at once and it seems to crank twice as fast as normal.
For sure, remove the cap on the valve cover where you add motor oil.
Take a good flashlight and peer intently inside. You will see the top of a valve and the valve spring just to the right of the opening. Have a helper crank the engine.
If it is a broken timing belt, the starter will turn the craknkshaft, but the valve will stay motionless.

Plastic object falling into gas tank while re-fueling


Yes it was just the top of the gas can so yeah it can be done cheaply basically all they will have to do is drain the gas and fuel injection and get it out of there, take it to your dealer or shop for more.

Car will start but won't stay running


Is the Check Engine Light on/ If yes, go to AUtozne & get codes read and report them here.

Also, try cleaning the MAF sensor and throttle bdy with spray carb cleaner.

Check for 40 psi of fuel pump pressure. Can you hear pump hum for 5 seconds when key is turned to ON? Listen at tank at rea of car, pump is in the tank.

My Saturn has been sitting in my driveway for about a year and a half. We just replaced the battery and the fuel filter and when I try to start the car, the engine turns over, starts for a minute, and then...


If the gas in tank is that old you need to drain it. Once you have good new,clean fuel in tank. Turn key to run position,(do not energize starter just want red lights on dash to come on) listen for fuelpump whine. It will shut off. Turn key off.Turn key to run again, listen for fuelpump again. Turn off key again. Repeat this procedure total 5 times. On last time turn key to engage starter. It should build up enough pressure & fuel & start right up.

Your 1989 cavalier is a 2 liter fuel injected engine so yes you do have a computer to run the engine so check your fuses and start with the simple and replace the fuel filter, air filter and clean the throttle body with throttle body cleaner. Don't use carburetor cleaner, the carburetor cleaner is to corrosive for the gaskets used in the throttle body. Also make sure all the vacuum lines are connected and not damaged, a bad vacuum line to the MAP sensor will cause what your having.
Good luck and keep us posted. Be glad to help you get your car running 100% again without the cost of a garage trying to be like the tax man.
